Description
Affiliated technical field
The utility model belongs to a kind of material disintegrating apparatus, relates generally to a kind of powerful counterattack fine crusher, is applicable to building materials, water power, highway, nonmetallic ore industry, in hard above material in, processing in small, broken bits.
Background technology
In industries such as building materials, water power, highway, nonmetallic mineral processing, usually need with in the hard above following material of material (as cobble, basalt etc.) feed size 80mm be processed as the aggregate of 25～5mm and less than the artificial sand of 5mm, the finished product particle shape is cube, faller gill shape content is few, once becomes sand coarse aggregate ratio to want high.Main at present employing JB/T3766-2000 hammer mill is finished, the processing in small, broken bits of following material (as lime stone) firmly during hammer mill only is fit to.When in the processing during hard above material, consumable accessory grating, tup service life only is about ten hours, and service life is short, change difficulty, and when processing the big material of water content, clay content, grating easily stops up, and production capacity is little.The hard rock impact breaker of broken use at present when directly processing the following sand of 25～5mm and 5mm, yields poorly, and the cost height must form closed-circuit system with vibratory sieve.
Summary of the invention
The purpose of this utility model provides a kind of powerful counterattack fine crusher, and it is long to make it have a consumable accessory life-span, changes convenient and simple characteristics.
The purpose of this utility model can adopt following technical scheme to realize: it comprises frame, power set, rotor block and back cavity plate, frame is formed by connecting by two bodies up and down, power set and rotor block interlock, the back cavity plate is two, be arcuate structure, the surface is provided with the counterattack liner plate, two back cavity plates are separately positioned on the lower bearing bracket, the upper end and the upper spider of the arc-shaped cavity plate of its middle and upper part are hinged, the lower end is connected with a connecting rod, the other end of connecting rod is arranged on the upper spider, one elastic buffering mechanism is set on the connecting rod, and the upper end and the upper spider of the arc-shaped cavity plate of bottom are hinged, and the bottom is connected with a connecting rod, the other end of connecting rod is positioned on the lower bearing bracket, and an elastic buffering mechanism is set on connecting rod.
Be symmetrically arranged with two access doors in the junction of upper and lower frame both sides.
The frame stationary plane and the ground that are used to install rotor block main shaft two end axles bearing have an angle of inclination.
Be provided with wedge-shaped slot at last arc lower back cavity plate, counterattack liner plate bottom is provided with wedge, and the wedge on the counterattack liner plate is arranged in wedge-shaped slot.
Described counterattack liner plate is a tooth-shape structure.
Bar on the rotor block is " " " shape.
Because the adjustable arc back cavity of two-stage plate wraps up nearly 180 ° with rotor block, and two-stage arc crusher chamber, from top to bottom, diminishes gradually.Owing to be that the fine crusher feed size is little, crusher chamber is also less.Two-stage arc crusher chamber all can be regulated, and can reach desired finished aggregate size.Material is subjected in two-stage arc back cavity repeatedly under the effect of multiple power such as bump, friction, shearing, and the finished product particle shape is good, and faller gill shape content is low.Because the disintegrating machine bottom do not have the grating device, to water content height, material processing that clay content is big, can not produce clogging, production capacity is unaffected.Frame helps the installation of rotor block owing to adopt upper and lower combining form, and two general overhaul doors of symmetry are set at upper and lower frame place.Open this when overhauling on the one hand and can observe gap between counterpunch board, the bar, on the other hand all rapid wear profile of tooth counterpunch boards and bar all can be thus door change, needn't open main frame as hammer mill or hard rock impact breaker, change simple, convenient like this.The counterattack liner plate adopts the assembling form of falling the wedge owing to adopt profile of tooth with the counterattack frame.During the material impacting counterpunch board, littler than flat pattern counterpunch board contact-making surface, there is cavity the centre like this, and material produces breaking force at this, easier fragmentation.Strike back liner plate and back cavity plate on the other hand and adopt the assembling form of falling the wedge, without the bolting form, both can prevent that bolt head wearing and tearing back counterpunch board from coming off, damage main frame, install again, convenient disassembly, need not open complete machine, take out, insert promptly replaceable from an end as long as open two large-scale access doors.Simple and convenient like this.Powerful counterattack fine crusher main bearing seat and lower bearing bracket adopt the tilting mounting means, compare with horizontal installation forms such as hammer mill, hard rock impact breakers, it is little to have shaft strength, bearing designation can be selected small-sized, bearing block takes up space little, increase space that access door is opened, can reduce cost again.
Hard above material in the brute force counterattack fine crusher processing of said structure, the product particle shape is good, and faller gill shape content is few, one-pass finished rate height, production capacity is big, and the consumable accessory life-span is long, change convenient and simplely, marker size is adjustable at any time, and processing water content height, the material that clay content is big are difficult for stopping up.Industries such as water power, urban architecture, highway have been solved, the demand of hard big, the costly building aggregate of above material (as cobble, basalt) process requirements amount of centering, express highway pavement building stones and artificial sand.Processed finished products is cube, and faller gill shape content is few, once become sand coarse aggregate ratio (less than 5mm) can reach more than 40～70%, and production capacity is big, and power consumption is few.Hard above material in the processing, about charging 80mm, time processing finished product 25～5mm reaches 30～40%, and less than the sand 40～70% of 5mm, production capacity is big, and cost is low, the consumable accessory long service life, it is convenient, simple to change.
