Description
Technical field
The present invention relates to disintegrating apparatus technical field, a kind of crushing pair with ultrafine grinding function and the implementation method of ultrafine grinding function thereof.
Background technology
Jaw crusher, also referred to as jaw are broken, are with the longest history, one of most popular disintegrating apparatus.
Jaw is broken is typical " slightly breaking " equipment.
Here thick breaking has two connotations:
One, jaw is broken is not accurate equipment, that is its simple in construction, (machine tool just can be competent at) easy to manufacture, use and keep in repair the most convenient, and operating cost that jaw is broken is the lowest, and (abrasion that such as jaw is broken is the 1/3-1/5 that counterattack is broken, power consumption is the 1/3-1/2 of impact cutting), therefore jaw is broken the most rather well received；
Two, jaw breaks the material being up to very thick (breaking fines to be difficult to, this breaking cavity structure broken with jaw is relevant), and usual jaw breaks to beat to below 30mm and is difficult to.
Imagination breaks fines with broken realization of jaw, and i.e. with the work of dry " carefully " level of the equipment of " slightly " level, the lifting amplitude of its economy is the most considerable！
Prior art jaw crusher lacks ultrafine grinding function, and it is limited in that:
One, crusher chamber is unreasonable.
1, under the prior art, in the lower end of the crusher chamber of " V " type, after each circulation stroke work done, discharge is the material of a pile triangle volume.Because jaw crusher is typical single-particl crushing (not having lamination crushing), so the granular size set of dimensions moderate that triangle volume accommodates is poor, it is high that discharging on-the-sieve material (exceeding the material of size up to specification) after screening returns heavily broken ratio, affects crushing efficiency；
2, it is not only that above-mentioned crusher chamber lower end to meet each broken rhythm (material of discharge is the most tiny) circulating stroke, or even whole crusher chamber (upper, middle and lower) all needs to meet rhythm of each broken circulation stroke, formed " some fraction cavity structures of crusher chamber ", and " level with level match compatibility ", ultrafine grinding function could be realized.
The structure of prior art crusher chamber is designed without considering " broken circulation stroke " this key factor.
Two, " Cracking Mechanism ' unreasonable.
Ultrafine grinding needs the Cracking Mechanism of " lamination crushing ", and prior art jaw breaks and do not possesses.
Jaw to be made breaks type and has ultrafine grinding function it is necessary to break through in the innovative design and its Cracking Mechanism of change of crushing pair.
Summary of the invention
It is an object of the invention to the defect overcoming prior art crusher chamber crushing efficiency the highest, it is provided that a kind of crushing efficiency is high, the province's power consumption that saves time and the crushing pair with ultrafine grinding function for jaw crusher and the implementation method of ultrafine grinding function thereof of fines can be beaten.
In order to reach object above, the present invention is achieved by the following technical solutions: a kind of crushing pair with ultrafine grinding function, forms two jaws of at least two-stage hierarchic structure formula crusher chamber including standing facing each other, it is characterised in that
The hierarchic structure formula crusher chamber that two described jaw work surface face-offs are formed from top to bottom is tapered into by level, angled stepped construction；
Two the jaw work surfaces being positioned at lower end afterbody crusher chamber in described hierarchic structure formula crusher chamber are sleeve configuration structure.
The two of the present invention are big, and notable architectural feature is: 1. crusher chamber is in " stepped construction "；2. crusher chamber lower end is provided with " sleeve configuration breaking chamber structure ".
Meanwhile, above-mentioned two big architectural features are also the two big technological highlights of the present invention simultaneously.
The technical scheme is that
1. routine crusher chamber is divided into some sections (being such as divided into 4 sections)；
2. the every one-level crusher chamber after setting up separately (becomes greatly) structure from the bottom to top step by step in staged；
3. crusher chamber foot one-level crusher chamber is sleeve configuration structure；
4. the design of sewing jaw " big pilled-in selvedge, big stroke " motion feature.
Sleeve configuration crusher chamber is the important component part in the present invention, is also one of core technology bright spot in the present invention.Sleeve configuration crusher chamber has five big features:
1, shape facility, is presented as that in terms of length and width length is the longest, and width is the narrowest；
2, angle character ,-8～+8 degree (with pilled-in selvedge state as standard)；
3, volume characteristic, the volume of sleeve configuration crusher chamber, should be the withdrawal rate of disintegrating machine cycle of operation each time；
4, motion feature, the motion feature of " big pilled-in selvedge, big stroke "；
5, functional character, lamination crushing, discharging ultrafine grinding.
Based on the sleeve configuration crusher chamber of crusher chamber bottom, draw the requirement of the stepped construction of whole crusher chamber.Stepped construction is another core technology bright spot in the present invention.
After above-mentioned sleeve configuration crusher chamber is arranged, solving " carefully " and " uniformly " two large problems of discharges material, this is our final purpose.
But sleeve configuration crusher chamber is in crusher chamber foot, crusher chamber is one entirety of upper and lower continuous print, in order to make sleeve configuration crusher chamber function give full play to, requires that again its upper end must feed fully, i.e. require that sleeve configuration upper level crusher chamber (for sake of convenience, is defined as Q2 chamber；Sleeve configuration crusher chamber is defined as Q1 simultaneously, lower same), Q2 chamber should meet following two conditions: 1, its volume should be equal to or more than the volume of sleeve configuration crusher chamber (for volume, Q2 >=Q1 should be met), 2, the granular size in Q2 chamber should be equal to or less than the size suitable for reading (for particle size, should meet Q2≤Q1) of sleeve configuration crusher chamber.Visible, the above of sleeve configuration crusher chamber needs the supporting of a Q2 chamber, and sleeve configuration crusher chamber could be allowed to give full play to the function of ultrafine grinding.
In like manner, needing also exist for a Q3 chamber to meet Q2 chamber on Q2 chamber, condition remains flow and granular size two key element；The most in like manner, also has Q4 above Q3 chamber ... (i.e. volume meets Q4 >=Q3 >=Q2 >=Q1；Granule meets Q4≤Q3≤Q2≤Q1)
Then, crusher chamber be the formation of by Q2, Q3, Q4 combined in stepped construction.The crusher chamber of stepped construction is not independent design, but the continuation of " sleeve configuration crusher chamber " function extends, and the important component part of disintegrating machine ultrafine grinding function.
To sum up analyze, ultrafine grinding function to be realized, the structure of crusher chamber is not the most random, it must break equipment each broken circulation work done rhythm operating and be associated with jaw, must the structure of each cycling element (every one-level crusher chamber) be staged again, and level and level match compatibility.
The present invention realizes the mechanism of ultrafine grinding function: first, according to jaw architectural feature, design using the crusher chamber bottom afterbody crusher chamber corresponding to the volume of each broken power cycles discharge material as first order crusher chamber, it is designed as sleeve configuration crusher chamber, this sleeve configuration crusher chamber realizes two big functions: 1. " in small, broken bits " function, i.e. chamber is adjustable to any little away from (two jaw spacing), to realize the in small, broken bits of any fineness；2. " uniformly " function, i.e. chamber away from well-balanced (unanimous on the whole along broken direction width).
Then, design using the crusher chamber bottom penultimate stage crusher chamber corresponding to the volume of each broken power cycles discharge material as second level crusher chamber, second level crusher chamber needs to meet two conditions for the purpose of the sufficient charging coordinating first order crusher chamber, 1, its volume should equal to or more than the volume of sleeve configuration crusher chamber, 2, its granular size should be equal to or less than the size suitable for reading of sleeve configuration crusher chamber ... the design of third level crusher chamber, the design of fourth stage crusher chamber ... by that analogy
Breaking, according to jaw, the crushing that each broken power cycles rhythm produces is unit, and the stepped construction crusher chamber designing " staged, and level and level match compatibility " is the core technology of the present invention.
The notable functional character of the present invention is: realize extraordinary, the crushing function of ultrafine grinding.As being aided with the supporting improvement of crusher structure again, the present invention can realize jaw and break the direct aggregate reclaiming of type unit, even crushes powder process.
Jaw is broken is " slightly " equipment, and sand processed, powder process are " carefully " work, and allowing " slightly " equipment do " carefully " work is an energy-saving and cost-reducing Green revolution！Break type with jaw and realize sand processed, powder process, be an important technical revolution in field of cracking machine！
In addition to above-mentioned notable functional character, the beneficial effect simultaneously brought also has:
1. improve yield.As being designed as shaped negative angle structures (referring to the angle that two jaw work surfaces are formed) at crusher chamber stepped construction of the present invention, then during crushing motion, material is had one to quickly propel power (if eccentric shaft turn to be set to consistent with logistics direction) by its jaw.This will increase substantially jaw bankruptcy amount.
Because the broken speed that prior art lower jaw is broken is natural free-fall velocity, is a ultimate value.The present invention breaches this limit velocity.
2. improve broken ratio.Level structure is got over, then the broken ratio of disintegrating machine can be increased substantially as being designed as segmentation in the stepped structure of crusher chamber of the present invention.Improve the crushing performance of disintegrating machine.
3. advantageously reduce abrasion.Cracking Mechanism in the present invention, has lamination crushing mechanism, and i.e. having substantial portion of material is " material dnockout ", thus abrasion are greatly lowered.
As preferably, the tooth-shape structure on two jaw work surfaces of hierarchic structure formula crusher chamber is the most also tapered into by level, and i.e. tooth depth is become narrow gradually by level by level gradually step-down, the facewidth and space width is tapered into by level, in profile of tooth hierarchic structure.
For adapting to material endfeed from crusher chamber, the practical situation that granule tapers into during the discharging of crusher chamber lower end, again crusher chamber is designed to profile of tooth hierarchic structure, i.e. tooth-shape structure size is tapered into by level from top to bottom, formula large granular materials is broken under big tooth-shape structure, small particles material is then broken under little tooth-shape structure, reaches optimum crushing efficiency.
As preferably, in the work surface of two jaws forming sleeve configuration structure, at least one piece is plane polish plate structure.
The design principle of plane polish plate structure: when the rank that granule is sand, powder, tooth-shape structure has lost broken meaning, by slab construction, available flat board instead of, is advantageous in that discharges material is more abundant, because not having tooth pitch to take lumen type space.
Plane polish plate structure is exactly tooth depth, the facewidth and space width limit state when being zero, and it is the structure falling behind, eliminating relative to tooth-shape structure, but here presents great advantage.Because in the afterbody chamber of multistage ladder crusher chamber, its broken object has been tiny material, and broken task is that fines homogenous superfine again is broken, is promoted as " mill " from " breaking ", and mill then can preferably ultrafine grinding (sand processed, powder process).
In sleeve configuration structure chamber, plane polish plate structure jaw has a following superiority:
1. for fines rank, it is no longer necessary to " split broken, roll over broken, squeeze broken " etc. need tooth-shape structure to complete effect, so tooth-shape structure have been out effect, the shortcoming of plane polish plate structure does not exists；
2. crushing fines very sensitive to lumen type precision, planar structure is higher than the contact surface precision of tooth-shape structure；
3. the tooth-shape structure of same stroke and plane polish plate structure, the former granular size differs, and more preferably, fine granules is more uniform for the latter's interlocking pattern.
Design one section of plane polish plate structure in the lower end (in sleeve configuration structure chamber) of crusher chamber, be the another technological highlights in the present invention.
As preferably, form the angular range of two jaw work surface face-off formation of sleeve configuration structure in-5 degree～+5 degree；A length of the 110 of sleeve configuration structure～550mm.
Sleeve configuration crusher chamber is the core technology bright spot of the present invention, has five big features:
1, shape facility.The lateral cross section length of sleeve configuration crusher chamber is longer, width relatively narrower, i.e. openning prolate；Longitudinally (broken direction) degree of depth is deeper；The determination of length L: by freely falling body formula h=1/2*g*t2Calculating, the rotating speed that prior art jaw breaks, at 180～330 revs/min, calculates length L between 110～550 millimeters；
2, angle character.Sleeve configuration crusher chamber is with pilled-in selvedge state as standard, and its angle is-5～+5 degree, is conducive to discharge unobstructed, is conducive to lamination crushing when choosing positive-angle, choose arranged material during zero degree the most uniform when choosing negative angle；
3, volume characteristic.The volume size of sleeve configuration crusher chamber is the withdrawal rate of disintegrating machine cycle of operation each time, and lumen type pilled-in selvedge size takes 1～3 times of discharge particle size.
4, motion feature.Sleeve configuration crusher chamber has the motion feature of " little pilled-in selvedge, big stroke "；
5, functional character.Sleeve configuration crusher chamber has " lamination crushing " mechanism, and discharging is ultra-fine.
The jaw of the present invention breaks the mechanism of lumen type sand powder process and is formed such that
1, being designed to " sleeve configuration crusher chamber " in crusher chamber bottom, the raw meal particle size making each cycle of operation of crusher chamber be given off controls in the range of required size, it is achieved even broken；
2, the upper end of every grade of crusher chamber ensures charging fully (i.e. particle size is more than volume less than charging aperture, flow), and one-level set one-level, angulation hierarchic structure, thus improves sleeve configuration crusher chamber work efficiency；
3, for adapting to the material situation that endfeed tapers into from crusher chamber to granule during the discharging of lower end, crusher chamber is designed to profile of tooth hierarchic structure, i.e. tooth-shape structure size is tapered into by level from top to bottom, make large granular materials broken under big tooth-shape structure, small particles material is broken under little tooth-shape structure, reaches purpose the most in small, broken bits；
4, the crushing motion being aided with " big pilled-in selvedge, big stroke " realizes " lamination crushing ".Jaw crusher is the most single Cracking Mechanism, and when broken coarse fodder, the pilled-in selvedge of substantially lumen type is sized at the particle size of material.Individually do not realize with the thinking ultrafine grinding (sand processed, powder process) of " single Cracking Mechanism ", because if lumen type pilled-in selvedge size is transferred to powder particle sizes, so: 1, the accuracy of manufacture and the installation accuracy of lumen type is difficult to reach, 2, under the trickleest lumen type, yield is the least, almost without practicality.
And the crushing motion of " big pilled-in selvedge, big stroke " realizes " lamination crushing mechanism ", so-called lamination crushing is broken exactly under the high pressure that " big stroke " produces, and has multilayer particle material, realize in small, broken bits by the way of material squeezes material between lumen type.So, lumen type pilled-in selvedge size is not necessarily particle size.It is to say, under " lamination crushing mechanism ", bigger pilled-in selvedge also can break excess of export fines (such as: the lumen type pilled-in selvedge size of 10～20mm, just can break off the powder of below 0.15mm).The origin cause of formation that formation lumen type high pressure crushes is " big stroke ", and under big stroke, inlet amount is big, produces the high high pressure crushed under ratio when big pilled-in selvedge and crushes, shows as lamination crushing mechanism.Under single Cracking Mechanism, " pilled-in selvedge " determines granular size, and " slack list " determines yield；Under lamination crushing mechanism, " big pilled-in selvedge, big stroke " i.e. determines ultra-fine granule, determines higher yield again.
The crushing motion of " big pilled-in selvedge, big stroke " then can realize " lamination crushing " mechanism, and so-called " lamination crushing " is exactly to have multilayer particle material in shattering process between lumen type, realizes in small, broken bits by the way of material pressing materials.So, lumen type pilled-in selvedge size is just not necessarily particle size, and bigger pilled-in selvedge also can break excess of export fines (such as: the lumen type pilled-in selvedge size of 10～20mm, can break off the powder of below 0.15mm).
As preferably, hierarchic structure formula crusher chamber is two-stage, three grades or level Four hierarchic structure；Two jaws of hierarchic structure formula crusher chamber are integral die-cast molding or are split spicing forming type.
Multiple stage crushing chamber is the bright spot of the present invention, and required progression is relevant with type size, and little type progression can lack, and big type progression should be many.
Overall structure is advantageous in that device structure is simplified, and it is convenient to change；Split type structure stock utilization is high, changes each time and only need to change the fritter that may wear to the end.
As preferably, in hierarchic structure formula crusher chamber, in addition to afterbody, every grade of crusher chamber shape is in " symmetrical formula " up-small and down-big trapezium structure, or " left and right asymmetric " up-small and down-big trapezium structure.
Multistage trapezium structure crusher chamber is suitable for broken hardness higher building material, and multistage rectangle meander line structure crusher chamber crushes the material bigger, hardness is relatively low needed for being suitable for crushing.
A kind of implementation method with ultrafine grinding function crushing pair, it is characterised in that include following content:
One, structure design (being positioned at whole crushing chamber of crusher foot) of sleeve configuration crusher chamber；
Jaw is broken is periodic cycle operating characteristic, and i.e. it is a cycle period with eccentric shaft every revolution.The charging rate broken due to jaw is free-fall velocity, so, as long as every disintegrating machine rotating speed determines, then the material drop (distance that i.e. material advances) in each circulation of disintegrating machine is exactly the numerical value determined.At this moment, further according to the lumen type width of required two pieces of jaws of raw meal particle size size adjusting, then each cycle of operation is discharged the volume namely numerical value determined of material.So, length L of sleeve configuration crusher chamber, width B, thickness H and volume V are defined below:
(1) determination of length L: by freely falling body formula h=1/2*g*t2Calculating, the rotating speed that prior art jaw breaks, at 180～330 revs/min, calculates length L between 110～550 millimeters；
(2) determination of thickness H: in practicality, thickness H is a variable, and it, according to required raw meal particle size size, can adjust within the specific limits at any time；
(3) determination of width B: after disintegrating machine type specification determines, whole crushing chamber of crusher width is certain value；
(4) determination of volume: after above length and width determines, the volume in each cycle of operation is exactly volume V=length L* width B* thickness H；
(5) determination of angle: the angle of sleeve configuration pair crusher chamber can select between-8～+8 degree, and has following three kinds of state features:
1. negative angle (reverse with V-arrangement crusher chamber angle, i.e. angle is down, is defined as negative angle, lower same) is conducive to discharges material, but can not be excessive, and excessive material is difficult to compacting；
2. positive-angle (with V-arrangement crusher chamber angle in the same direction, i.e. angle is down, is defined as negative angle, lower same) is conducive to broken fines, but also unsuitable excessive, and excessive being unfavorable for uniformly crushes；
3. zero degree, is advantageous for material in theory and uniformly crushes, but owing to sewing jaw is to make " fan-shaped " motion with eccentric shaft for the center of circle, and jaw is in again among constantly abrasion change, therefore zero degree is only theory analysis point and moment transient state, practical significance is little.
The angle of crusher chamber is a dynamic concept, and we to study and to hold is feature and the function of an angular range, and the applicant is set between-8～+8 degree.
The design of above-mentioned sleeve configuration crusher chamber, solves " carefully " and " uniformly " two large problems of discharges material.
Two, crusher chamber stepped construction design
Drafting whole crushing chamber of crusher foot crusher chamber is Q1, i.e. sleeve configuration crusher chamber, with its upper level crusher chamber as Q2, and Q3, Q4 by that analogy...；
The design of the 1. angle stepped construction of whole crusher chamber and the design of 2. profile of tooth stepped construction are described whereby；
1. the design of angle stepped construction
Above-mentioned sleeve configuration crusher chamber is in crusher chamber foot, and crusher chamber is one entirety of upper and lower continuous print, in order to make sleeve configuration crusher chamber function give full play to, require that again its upper end must feed fully, i.e. require that sleeve configuration crusher chamber has again a corresponding chamber (for sake of convenience, to be defined as Q2 chamber；Sleeve configuration crusher chamber is defined as Q1 simultaneously, lower same), Q2 chamber should meet following two conditions: 1, volume during its pilled-in selvedge should be equal to or more than volume during sleeve configuration crusher chamber slack list (for volume, Q2 >=Q1 should be met), 2, the largest particles during pilled-in selvedge of Q2 chamber, should be equal to or less than the size suitable for reading (for particle size, Q2≤Q1 should be met) during sleeve configuration crusher chamber slack list.Visible, the above of sleeve configuration crusher chamber needs the supporting of a Q2 chamber, and sleeve configuration crusher chamber could be allowed to give full play to the function of ultrafine grinding.
In like manner, needing also exist for a Q3 chamber to meet Q2 chamber on Q2 chamber, condition remains " volume " and " granular size " two key element；The most in like manner, also has Q4 above Q3 chamber ... (i.e. volume meets Q4 >=Q3 >=Q2 >=Q1；Granule meets Q4≤Q3≤Q2≤Q1)
Then, crusher chamber is the formation of " stepped construction " combined by Q2, Q3, Q4.The crusher chamber of stepped construction is not independent design, but the continuation of " sleeve configuration crusher chamber " function extends, and it is the important component part of disintegrating machine ultrafine grinding function equally.
2. the design of profile of tooth stepped construction
The determination of profile of tooth: the tooth-shape structure on two jaw work surfaces of hierarchic structure formula crusher chamber is the most also tapered into by level, i.e. tooth depth become narrow gradually by level by level gradually step-down, the facewidth and space width is tapered into by level, in profile of tooth hierarchic structure；
For adapting to material endfeed from crusher chamber, the situation that granule tapers into during the discharging of crusher chamber lower end, again crusher chamber is designed to " profile of tooth hierarchic structure ", the i.e. size of tooth-shape structure is tapered into by level the most from top to bottom, i.e. large granular materials is broken under big tooth-shape structure, small particles material is then broken under little tooth-shape structure, reaches optimum crushing efficiency；
To sum up analyze, ultrafine grinding function to be realized, the structure of crusher chamber is not the most arbitrarily design, it is governed by its rule, it must break the work done rhythm of each broken circulation during equipment runs and be associated with jaw, make the double stepped construction (angle ladder and profile of tooth ladder) of level and level composition, and level and level match compatibility；In each broken cycling element (every one-level crusher chamber), all can realize optimal crushing effect,
Three, the design of lamination crushing mechanism
Realizing " ultrafine grinding " function, the innovative design of above-mentioned crusher chamber is a basis, but " lamination crushing " mechanism is prior link.Depend alone crusher chamber gap (distances between two jaws) determine stock product granular size be have the most circumscribed.When being especially crushed to the fines of sand, powder rank.Because, crusher chamber gap be adjusted to millimeter, micron rank the most unpractical.And under lamination crushing mechanism, under the conditions of the wide arc gap of crusher chamber, the ultra-fine material of sand, powder rank but (under the biggest pilled-in selvedge), can be realized.
The determination of stroke: lamination crushing mechanism to be realized, it is necessary to the stroke under breaking prior art jaw expands more than 3 times.Design activity jaw " big pilled-in selvedge, big stroke " motion feature；Crushing motion should meet: 1, in each broken circulation, and volume during a upper chamber pilled-in selvedge should be greater than volume during next slack list, chamber；Size suitable for reading during the pilled-in selvedge in 2, a upper chamber should be less than bottom size during next slack list, chamber.
Four, the lifting of disintegrating machine mechanical structure
In using " lamination crushing " mechanism, needs have the jaw motion feature of " big stroke " and have the mechanics mechanism of enough " reinforcement effect ", this is relevant to the overall structure of crusher, prior art jaw is broken does not possess this two conditions, and before the applicant, dual-crank-rocker mechanism disintegrating machine and the compound crank and rocker mechanism disintegrating machine of application meet above-mentioned condition.
Sum it up, jaw breaks type ultrafine grinding to be realized function, by three, " key element " is integrated greatly forms: " lumen type+type+mechanism ".
1. " sleeve configuration structure ", the innovative design of " stepped construction " crusher chamber are bases；
2. " dual-crank-rocker mechanism disintegrating machine " and " compound crank and rocker mechanism disintegrating machine " is necessary and sufficient condition；
3. " lamination crushing mechanism " is core.

A kind of implementation method with ultrafine grinding function crushing pair, it is characterised in that include following content:
One, structure design (being positioned at whole crushing chamber of crusher foot) of sleeve configuration crusher chamber；
Jaw is broken is periodic cycle operating characteristic, and i.e. it is a cycle period with eccentric shaft every revolution.The charging rate broken due to jaw is free-fall velocity, so, as long as every disintegrating machine rotating speed determines, then the material drop (distance that i.e. material advances) in each circulation of disintegrating machine is exactly the numerical value determined.At this moment, further according to the lumen type width of required two pieces of jaws of raw meal particle size size adjusting, then each cycle of operation is discharged the volume namely numerical value determined of material.So, length L of sleeve configuration crusher chamber, width B, thickness H and volume V are defined below:
(1) determination of length L: by freely falling body formula h=1/2*g*t2Calculating, the rotating speed that prior art jaw breaks, at 180～330 revs/min, calculates length L between 110～550 millimeters；
(2) determination of thickness H: in practicality, thickness H is a variable, and it, according to required raw meal particle size size, can adjust within the specific limits at any time；
(3) determination of width B: after disintegrating machine type specification determines, whole crushing chamber of crusher width is certain value；
(4) determination of volume: after above length and width determines, the volume in each cycle of operation is exactly volume V=length L* width B* thickness H；
(5) determination of angle: the angle of sleeve configuration pair crusher chamber can select between-8～+8 degree, and has following three kinds of state features:
1. negative angle (reverse with V-arrangement crusher chamber angle, i.e. angle is down, is defined as negative angle, lower same) is conducive to discharges material, but can not be excessive, and excessive material is difficult to compacting；
2. positive-angle (with V-arrangement crusher chamber angle in the same direction, i.e. angle is down, is defined as negative angle, lower same) is conducive to broken fines, but also unsuitable excessive, and excessive being unfavorable for uniformly crushes；
3. zero degree, is advantageous for material in theory and uniformly crushes, but owing to sewing jaw is to make " fan-shaped " motion with eccentric shaft for the center of circle, and jaw is in again among constantly abrasion change, therefore zero degree is only theory analysis point and moment transient state, practical significance is little.
The angle of crusher chamber is a dynamic concept, and we to study and to hold is feature and the function of an angular range, and the applicant is set between-8～+8 degree.
The design of above-mentioned sleeve configuration crusher chamber, solves " carefully " and " uniformly " two large problems of discharges material.
Two, crusher chamber stepped construction design
Drafting whole crushing chamber of crusher foot crusher chamber is Q1, i.e. sleeve configuration crusher chamber, with its upper level crusher chamber as Q2, and Q3, Q4 by that analogy...；
The design of the 1. angle stepped construction of whole crusher chamber and the design of 2. profile of tooth stepped construction are described whereby；
1. the design of angle stepped construction
Above-mentioned sleeve configuration crusher chamber is in crusher chamber foot, and crusher chamber is one entirety of upper and lower continuous print, in order to make sleeve configuration crusher chamber function give full play to, require that again its upper end must feed fully, i.e. require that sleeve configuration crusher chamber has again a corresponding chamber (for sake of convenience, to be defined as Q2 chamber；Sleeve configuration crusher chamber is defined as Q1 simultaneously, lower same), Q2 chamber should meet following two conditions: 1, volume during its pilled-in selvedge should be equal to or more than volume during sleeve configuration crusher chamber slack list (for volume, Q2 >=Q1 should be met), 2, the largest particles during pilled-in selvedge of Q2 chamber, should be equal to or less than the size suitable for reading (for particle size, Q2≤Q1 should be met) during sleeve configuration crusher chamber slack list.Visible, the above of sleeve configuration crusher chamber needs the supporting of a Q2 chamber, and sleeve configuration crusher chamber could be allowed to give full play to the function of ultrafine grinding.
In like manner, needing also exist for a Q3 chamber to meet Q2 chamber on Q2 chamber, condition remains " volume " and " granular size " two key element；The most in like manner, also has Q4 above Q3 chamber ... (i.e. volume meets Q4 >=Q3 >=Q2 >=Q1；Granule meets Q4≤Q3≤Q2≤Q1)
Then, crusher chamber is the formation of " stepped construction " combined by Q2, Q3, Q4.The crusher chamber of stepped construction is not independent design, but the continuation of " sleeve configuration crusher chamber " function extends, and it is the important component part of disintegrating machine ultrafine grinding function equally.
2. the design of profile of tooth stepped construction
The determination of profile of tooth: the tooth-shape structure on two jaw work surfaces of hierarchic structure formula crusher chamber is the most also tapered into by level, i.e. tooth depth become narrow gradually by level by level gradually step-down, the facewidth and space width is tapered into by level, in profile of tooth hierarchic structure；
For adapting to material endfeed from crusher chamber, the situation that granule tapers into during the discharging of crusher chamber lower end, again crusher chamber is designed to " profile of tooth hierarchic structure ", the i.e. size of tooth-shape structure is tapered into by level the most from top to bottom, i.e. large granular materials is broken under big tooth-shape structure, small particles material is then broken under little tooth-shape structure, reaches optimum crushing efficiency；
To sum up analyze, ultrafine grinding function to be realized, the structure of crusher chamber is not the most arbitrarily design, it is governed by its rule, it must break the work done rhythm of each broken circulation during equipment runs and be associated with jaw, make the double stepped construction (angle ladder and profile of tooth ladder) of level and level composition, and level and level match compatibility；In each broken cycling element (every one-level crusher chamber), all can realize optimal crushing effect,
Three, the design of lamination crushing mechanism
Realizing " ultrafine grinding " function, the innovative design of above-mentioned crusher chamber is a basis, but " lamination crushing " mechanism is prior link.Depend alone crusher chamber gap (distances between two jaws) determine stock product granular size be have the most circumscribed.When being especially crushed to the fines of sand, powder rank.Because, crusher chamber gap be adjusted to millimeter, micron rank the most unpractical.And under lamination crushing mechanism, under the conditions of the wide arc gap of crusher chamber, the ultra-fine material of sand, powder rank but (under the biggest pilled-in selvedge), can be realized.
The determination of stroke: lamination crushing mechanism to be realized, it is necessary to the stroke under breaking prior art jaw expands more than 3 times.Design activity jaw " big pilled-in selvedge, big stroke " motion feature；Crushing motion should meet: 1, in each broken circulation, and volume during a upper chamber pilled-in selvedge should be greater than volume during next slack list, chamber；Size suitable for reading during the pilled-in selvedge in 2, a upper chamber should be less than bottom size during next slack list, chamber.
Four, the lifting of disintegrating machine mechanical structure
In using " lamination crushing " mechanism, needs have the jaw motion feature of " big stroke " and have the mechanics mechanism of enough " reinforcement effect ", this is relevant to the overall structure of crusher, prior art jaw is broken does not possess this two conditions, and before the applicant, dual-crank-rocker mechanism disintegrating machine and the compound crank and rocker mechanism disintegrating machine of application meet above-mentioned condition.
Sum it up, jaw breaks type ultrafine grinding to be realized function, by three, " key element " is integrated greatly forms: " lumen type+type+mechanism ".
1. " sleeve configuration structure ", the innovative design of " stepped construction " crusher chamber are bases；
2. " dual-crank-rocker mechanism disintegrating machine " and " compound crank and rocker mechanism disintegrating machine " is necessary and sufficient condition；
3. " lamination crushing mechanism " is core.
The embodiment of the above is only the preferred embodiments of the invention, not limits the practical range of the present invention with this, therefore the change that all shapes according to the present invention, principle are made, all should contain within the scope of the present invention.
