Description
Technical field
The present invention relates to the improvement of vertical offcenter crusher and method of operation thereof, more particularly, although relate to simple in structure but allow broken raw material once just can obtain repeatedly broken whole grain effect and high vertical offcenter crusher and the method for operation thereof of the productivity ratio of crushed product by rotary body.
Background technology
As by with broken raw material to horizontal direction projection and make its shock surface that collides broken thing layer and, the following describes typical conventional example with the vertical offcenter crusher of broken raw material fragmentation.
The centrifugal whole grain device (hereinafter referred to as vertical offcenter crusher) of conventional example 1,2, utilize the centrifugal force that rotation produced of rotor (rotary body), throw away (projection) material (hereinafter referred to as broken raw material) to enclosure interior, thereby carry out the broken or whole grain of broken raw material around this rotor.That is, this disintegrating machine of conventional example 1,2, the bottom that falls mouth that forms between first housing that constitutes above-mentioned housing and the first rotor also is provided with second rotor.In addition, be provided with second housing, and on the upper surface complete cycle of the said first shell and second housing, be provided with material from material to the first rotor that supply with and supply with the ventilating opening that the middle part of tube is communicated with in the periphery of this second rotor.This disintegrating machine of conventional example 1,2 is intended to improve by the first rotor and this two-stage rotor of second rotor effect (for example, open flat 1-137739 communique and open flat 2-4630 communique in fact with reference to real) of the broken and whole grain of broken raw material.
In addition, in the disintegrating machine of conventional example 3, in the cabinet inside of (being equivalent to the disintegrating machine main body), rotary body (hereinafter referred to as rotor) is rotated axle (rotor main shaft) supporting, and has been provided with end rotating cylinder in above-mentioned centre of rotor portion.There is the side of end rotating cylinder to be provided with the raw material vent gap at this, and is being provided with on the above-mentioned rotor through impact that broken raw material collided of raw material emission quotas in this gap discharging process.That is, son impacts and broken aloft broken raw material (for example, with reference to No. 1175436 communiques of special permission) by impacting.
In addition, the disintegrating machine of conventional example 4 utilizes the frictional resistance of centrifugal force and guide surface and discharges broken raw material with low velocity.And the shock surface that broken raw material is collided on the flight path that is configured in broken raw material also rebounds, and the broken raw material of bounce-back is collided on the shock surface that is arranged at the equipment body side.That is, by twice collision at short notice and effectively with broken raw material fragmentation (for example, opening flat 10-137605 communique) with reference to the spy.
The device of conventional example 1 to 4 has following problem to be solved respectively.At first, in the disintegrating machine of conventional example 1,2, second rotor is supported by rotor main shaft, and the first rotor is supported in second rotor top.Therefore, the center of gravity of the first rotor from the bearing position of rotor main shaft away from, so be easy to produce abnormal vibrations, and strengthen because of partial load makes the burden of bearing, thereby must adopt the big bearing of load capacity, must sub-economic problem in the design of vertical offcenter crusher thereby exist.
In addition, because the first rotor is positioned at eminence, so the above-below direction size of vertical offcenter crusher is big, the position height of raw material input port, result, the problem that exists the relevant device cost of vertical offcenter crusher also to increase.Have again, even under the situation of maintenance operation of wearing and tearing, because the complex structure and the volume of rotor are big, so the required time of maintenance operation of wearing and tearing is also long, and the problem that exists required operating cost also to increase.
For example, owing to drive rotor to rotate at a high speed, thus need to realize the weight balancing of rotor main shaft and rotor, if the height till rotor is low, even only realize that then static balance also is enough to practicality.But, under the high situation of the height till rotor,, not only to realize the balance of horizontal direction with respect to the height till rotor, also to realize the balance of vertical direction, otherwise will cause and rock.Therefore, also must realize dynamic balancing, so unfavorable aspect the cost of vertical offcenter crusher by improving measures such as assembly precision.
Under the situation of the rotor of the vertical offcenter crusher of conventional example 3, only for the formation of raw material floss hole is set on cylinder.Therefore, only be that dispersion is discharged broken raw material and can not be quickened to throw broken raw material, so the mass rate of emission instability of broken raw material, flight path is discrete.So, for dispersing of reply flight path, must enlarge the area of the shock surface that impacts son, the problem that exists the running stores expense to increase.In addition, impact portions is used hard material, is to be target with the crushing effect in essence, so whole grain effect is limited.
In the vertical offcenter crusher of conventional example 4,,, can make broken raw material discrete because of the influence of wind, the reasons such as situation that contact with wear surface owing to be with the broken raw material of low velocity discharge.Therefore, be difficult to make on the appropriate location of whole broken raw material collision shock surfaces of performance crushing effect when collision, if discrete broken raw material collision is then given a little less than the impulsive force of broken raw material, so crushing effect descends more leaning on the position of axle central side than the appropriate location.In addition, owing on the broken raw material of catching on the surface of shock surface is surface at shock surface, slide the back projection, so there is the bigger problem of the surface abrasion of rotary impact parts.
In addition, a little less than the centrifugal gravity of the broken raw material that centrifugal force produced that acts on during the discharging of broken raw material with respect to the guide surface of the guide surface of preparation guide member, guide member, and the dispersion on the short transverse of the radiation position of rotor is relatively poor, concentrates downwards because of the influence of gravity and flows.Therefore, the local thickening of the bed thickness of broken raw material, a lot of broken raw materials be subjected to bed thickness influence and can the direct collision shock surface, so crushing force can descend when throughput increases.Because the influence of the velocity of projection of broken raw material collides the velocity of discharge of the broken raw material behind the shock surface, so the hold-up of broken raw material increases on the shock surface when the velocity of projection of broken raw material is slow, this will hinder the broken raw material that throwed to the shock surface direct collision, thereby can not apply stronger impulsive force to a large amount of broken raw materials.That is can not carry out the problem of effective fragmentation, break process ability drop when, exist supplying with a large amount of broken raw material.
Summary of the invention
Although the purpose of this invention is to provide a kind of simple in structure and compact but allow broken raw material once can obtain repeatedly broken whole effect and high vertical offcenter crusher and the method for operation thereof of the productivity ratio of crushed product through rotary body.
The vertical offcenter crusher that one aspect of the present invention relates to, possess disintegrating machine main body and rotary body, described rotary body is that pivot is rotated and has an a plurality of raw materials projection mouthful with the vertical axis, described a plurality of raw material projection mouth is used for will putting into from the raw material input port that is arranged on this pivot by centrifugal force the broken raw material radius vector of disintegrating machine body interior and throws to foreign side, make week in the crushing chamber of this fragmentation raw material collision disintegrating machine main body broken thing layer (deadstock, deadbed).Wherein, described rotary body possesses first raw material projection mechanism and second raw material projection mechanism, described first raw material throws mechanism and comprises that the first broken thing layer that forms the first broken thing layer forms plate, the broken raw material that the described first broken thing layer will be put into the disintegrating machine body interior from described raw material input port by centrifugal force throws to foreign side through surperficial radius vector, described second raw material projection mechanism is arranged on than described first raw material projection mechanism away from described pivot, and from the position that the broken raw material of this first raw material projection mechanism projection is collided, make broken raw material after the collision broken and should the fragmentation raw material mouthful discharge to foreign side's projection and from described raw material projection through surperficial radius vector by centrifugal force.
According to the present invention, available second raw material throws mechanism the broken raw material from the projection of first raw material projection mechanism is carried out primary fragmentation, then the broken raw material behind the primary fragmentation is throwed from second raw material projection mechanism, and carry out second-time breakage with the broken thing layer in week in the crushing chamber of disintegrating machine main body, so can obtain whole grain crushed product.
In addition, according to the present invention, rotary body is one.Therefore, compacter and simple in structure than the vertical offcenter crusher of conventional example 1,2, so favourable for the cost of vertical offcenter crusher self.In addition, because the balance adjustment of rotary body is easy, so the upkeep operation required time is shorter, thereby also favourable for maintenance cost.
Have again, because second raw material projection mechanism is located at than on the position of first raw material projection mechanism away from pivot, the peripheral speed of second raw material projection mechanism is a fair speed, broken in addition raw material quickens projection by first raw material projection mechanism, after colliding on the shock surface of second raw material projection mechanism, broken and be dispersed on the shock surface of this second raw material projection mechanism, then, after the direction of rotation upstream side of second raw material projection mechanism moves, be projected onto rotary body foreign side again.At this moment, the flight path of broken raw material just can not disperseed, thus can efficient well with broken raw material fragmentation.
In addition, in the above-described configuration, preferably, described second raw material projection mechanism comprises that the second broken thing layer that forms the second broken thing layer forms plate, and the described second broken thing layer throws to foreign side through surperficial radius vector for the broken raw material after will colliding from the broken raw material collision of described first raw material projection mechanism projection and by centrifugal force.
Under this situation, vertical offcenter crusher makes from the broken raw material of first raw material projection mechanism projection and throws the broken thing layer collision of mechanism and carry out fragmentation and whole grain to second raw material.Therefore, the broken thing layer of second raw material projection mechanism is regenerated successively and can not be consumed, so the running stores expense can not increase.
In addition, in above-mentioned arbitrary formation, preferably, described second raw material projection mechanism is made of the fragmentation projection plate of hard material system.
Under this situation, vertical offcenter crusher makes from the broken raw material of first raw material projection mechanism projection and throws the plate fragmentation by the fragmentation of the hard material system of second raw material projection mechanism.Therefore, though running stores expense aspect with possess vertical offcenter crusher that the second broken thing layer forms plate compare comparatively unfavorable, can be more effectively with broken raw material fragmentation.
In addition, in above-mentioned arbitrary formation, preferably, the radius R 1 till from the pivot of described rotary body to described first raw material projection mechanism end and from the pivot of described rotary body to described second raw material projection mechanism end till the ratio R2/R1 of radius R 2, be set at more than 1.2.
Under this situation, will be from the pivot of rotary body to first raw material radius R 1 till the projection mechanism end and from the pivot of rotary body to second raw material projection mechanism end till the ratio R2/R1 of radius R 2 be set at more than 1.2.Therefore, according to the present invention, quicken and the velocity of projection of the broken raw material that throwed and should the speed difference of fragmentation raw material between the speed of second raw material projection mechanism collision bigger by first raw material projection mechanism, so can apply effective crushing effect to broken raw material by second raw material projection mechanism.
The method of operation of the vertical offcenter crusher that the present invention relates on the other hand, with the peripheral speed V1 that throws the position of broken raw material from above-mentioned first raw material projection mechanism is mode more than the 20m/s, makes the rotor rotation of the vertical offcenter crusher with above-mentioned arbitrary formation.
Under this situation, except the effect of vertical offcenter crusher with the invention described above, because after broken raw material collides on the shock surface of first raw material projection mechanism, direction of rotation upstream side towards this first raw material projection mechanism moves, then, mainly throw towards the locality of second raw material projection mechanism by first raw material projection mechanism, so can make the projection stability-of-path from the terminal position of this first raw material projection mechanism.And, owing to suppressed the diffusion of the projection track of broken raw material, can make broken raw material collide both allocations of second raw material projection mechanism.Have, if for to make the peripheral speed V1 that throws the position of broken raw material from above-mentioned first raw material projection mechanism be more than the 20m/s then can obtain the fact of above-mentioned effect, the inventor confirms by actual confirmatory experiment again.

In addition, in the interior week of the cylindrical portion of upper body 2a, be provided with the broken thing layer that forms broken thing layer and form plate 4, this fragmentation thing layer forms plate 4 and comprises the plectane of horizontal hollow and be installed in the internal side diameter ora terminalis of this plectane and will plate shapedly become the end vertical panel of circle.And, form in the zone that face surrounded of interior all sides of cylindrical portion of upper surface, end vertical panel of the horizontal hollow plectane of plate 4 at the inner peripheral surface of the cylindrical portion of upper body 2a, broken thing layer, form broken thing layer (broken body) 4a of main body side along the inner peripheral surface of cylindrical portion.
Radial center position at lower case 2b vertically disposes rotor main shaft support unit 5.In the radial center portion of this rotor main shaft support unit 5, upper bearing 5a that is held in the bearing accommodation section of upper and lower side and lower bearing 5b and supporting rotor main shaft 6 through being arranged on this rotor main shaft support unit 5.This rotor main shaft 6 constitutes, and can rotate by being inlaid in from the V-belt belt wheel 6b of the outstanding downwards lower end of rotor main shaft support unit 5.The base end side of rotor main shaft support unit 5 is fixed on the inner peripheral surface of lower case 2a, and on the other hand, its end side is fixed on many backbar 2d supportings on the outer peripheral face of rotor main shaft support unit 5.In addition, the space between lower case 2b and the rotor main shaft support unit 5 is as the crushed product passage that falls.And, have as the crushed product outlet 2c that discharges crushed product in the lower side of this lower case 2b.
On the top of rotor main shaft 6, supporting aftermentioned rotor 7 by 6 rotations of this rotor main shaft.This rotor 7 possesses discoideus upper plate 7a, and upper plate 7a has the circular port that runs through for the lower end of above-mentioned raw material input tube 3 in the radial center position.In addition, possesses discoideus lower plate 7b, this lower plate 7b has the circular port that runs through for the distributor of circular cone shape (distributor) 6a roughly equally in center radially, the upper end of this distributor 6a and rotor main shaft 6 links, and the broken raw material that drops into from raw material input port 3a is to all the winds disperseed.And, the first broken thing layer of above-mentioned upper plate 7a and the lower plate 7b part by being configured in a plurality of formations first raw material projection mechanism 8 between this upper plate 7a and the lower plate 7b form plate 8a, and the second broken thing layer that constitutes the part of second raw material projection mechanism 9 form that plate 9a connects and one constitutes.
The first broken thing layer that constitutes the part of first raw material projection mechanism 8 forms plate 8a, be positioned at the position near the pivot O of rotors 7, and uniformly-spaced be disposed on the roughly round line that pivot O with this rotor 7 is the center (roughly on the circumference) everywhere than aftermentioned second raw material projection mechanism 9.In the present embodiment, the first broken thing layer forms plate 8a and roughly possesses backplate 8d on the consistent location at the diameter line with pivot O by rotor 7.In addition, the first broken thing layer forms plate 8a and has the base plate 8e that the mode that bloats with the outer circumferential side direction to rotor 7 is bent to form.In addition, this backplate 8d is bonded on the end that the first broken thing layer forms the direction of rotation downstream of plate 8a, the just end of base plate 8e.
Be provided with on base plate 8e, from the section of Fig. 2, its part is the line part with the tangent line almost parallel of rotor 7 periphery circular arcs.On the end of the opposite side of a side that engages with backplate 8d of the line part of base plate 8e, the cutter head installing plate 8f that is used to assemble the cutter head of imbedding hard blade etc. and forming is installed.In addition, the recess to the pivot O of rotor 7 side opening between plate 8d, base plate 8e and the cutter head installing plate 8f forms the first broken thing layer 8b overleaf.Have, broken raw material is throwed everywhere from the first broken thing layer 8b's again, but the end of main cutter head from the cutter head installing plate 8f that is installed in the first broken thing layer formation plate 8a is throwed.This launching position is called the first launching position 8c that throws broken raw material.Say that more stable for the projection track that makes the broken raw material that penetrates from first raw material projection mechanism 8, preferably, broken raw material all penetrates from the first launching position 8c.
The second broken thing layer that constitutes the part of second raw material projection mechanism 9 forms plate 9a and is positioned at the outer circumferential side of rotor 7, and uniformly-spaced is disposed on the roughly round line that pivot O with rotor 7 is the center everywhere.This second broken thing layer forms the backplate 9d that plate 9a possesses the backplate 8d almost parallel of the lateral surface and the first broken thing layer formation plate 8a.In addition, possess with heading joint and be combined in flat base plate 9e on the rotor 7 outer circumferential side ends of this backplate 9d.In addition, at the end of base plate 9e, possesses the end plate 9f that engages with this base plate 9e right angle.
Have again,, be formed with the second broken thing layer 9b at the recess that is formed between backplate 9d, base plate 9e and the end plate 9f to the roughly pivot O of rotor 7 side opening.And, the second broken thing layer forms plate 9a, receive from the next broken raw material of first raw material projection mechanism 8 (comprising the first launching position 8c) projection at the second broken thing layer 9b, the broken raw material of this reception is mainly gone out by projection from the terminal that is second launching position 9c of end plate 9f.At this moment, more stable for the projection track that makes the broken raw material that penetrates from second raw material projection mechanism 9, preferably, broken raw material all penetrates from the second launching position 9c.Have, second raw material projection mechanism 9 space each other of rotor 7 becomes raw material projection mouth 10 respectively again.
Distance such as the following setting separately of first raw material projection mechanism 8 and second raw material projection mechanism 9 from the pivot O of rotor 7 to launching position.That is, from the pivot O of rotor 7 to first raw material radius R till projection mechanism's 8 ends (the first launching position 8c just) 1 with from the pivot O of rotor 7 to second raw material projection mechanism's 9 ends (the second launching position 9c just) till the ratio R2/R1 of radius R 2 be set at more than 1.2.
In other words, the peripheral speed at second raw material projection mechanism, 9 ends that is the second launching position 9c place is set at more than 1.2 times of peripheral speed at first raw material projection mechanism, 8 ends that is the first launching position 8c place.Why set peripheral speed in the mode that reaches the ratio more than 1.2 like this and compare R2/R1, be for by increasing, obtain the broken and whole effect of bigger broken raw material from the speed difference of the impact velocity of first velocity of projection of the broken raw material of first launching position 8c projection and second raw material projection mechanism.
Promptly, this be because, at aforementioned proportion R2/R1 less than 1.2 o'clock, little from the speed difference of the impact velocity of first velocity of projection of the broken raw material of first launching position 8c projection and second raw material projection mechanism, can not obtain enough crushing effects that second raw material projection mechanism 9 is produced, this has just lost the meaning that this second raw material projection mechanism 9 is set.Have, in order to obtain bigger crushing effect, ratio R2/R1 is preferably more than 1.5 again, and ratio R2/R1 is more preferably more than 1.8.The higher limit of ratio R2/R1 can wait suitably according to for example economic cause to be determined.
Fragmentation is once at least in rotor 7 with broken raw material for the vertical offcenter crusher 1 of present embodiment one.Particularly, at first, for obtaining crushing effect and whole grain effect, vertical offcenter crusher 1 makes by 8 acceleration of first raw material projection mechanism and from for example first launching position 8c radius vector and collides second raw material projection mechanism 9 and carry out primary fragmentation (again, carrying out precrushing from the broken raw material collision of raw material input port 3a sometimes in first raw material projection mechanism 8) to the broken raw material of foreign side's projected at high velocity.Then, from for example second launching position 9c of second raw material projection mechanism 9 radially foreign side projection, and make its collision on the broken thing layer of the main body side 4a that forms in interior week of the upper body 2a of disintegrating machine main body 2 and carry out second-time breakage this broken raw material that has carried out primary fragmentation to rotor 7.
The following describes the mode of action of the vertical offcenter crusher of embodiment of the present invention one.
In vertical offcenter crusher 1, with broken raw material when broken, at first through rotation by motor rotor rotated main shaft 6 beginning rotors 7, described motor can be set for by not shown speed setting mechanism, makes that the peripheral speed at the first launching position 8c place of rotor 7 is the above set value of 20m/s.So, the rotating speed of rotor 7 rises gradually, after the peripheral speed V1 at the first launching position 8c place of first raw material projection mechanism 8 reaches setting value more than the 20m/s, drop into broken raw material from the raw material input port 3a of raw material input tube 3 upper ends, the broken raw material that drops into drops in the rotor 7,6a to all the winds disperses by distributor, and is caught by the first broken thing layer 8b of first raw material projection mechanism 8 of rotating.
Why the mode that reaches more than the 20m/s with the peripheral speed V1 at the first launching position 8c place of first raw material projection mechanism 8 is rotated rotor 7, reason is, at the peripheral speed V1 at the first launching position 8c place during less than 20m/s, on broken raw material, can not act on enough centrifugal force, broken raw material is the direction situation variation of disperseing up and down at the first raw material launching position 8c place, is difficult to make the broken raw material collision of projection on both allocations of the second broken thing layer 9b of second raw material projection mechanism 9.That is, this is because the broken raw material that throws the first launching position 8c projection of mechanism 8 from first raw material spreads with the first projection track, 11 unsure states.Therefore, more stable for the first projection track 11 that makes broken raw material, preferably making rotor 7 is that mode more than the 25m/s is rotated with the peripheral speed V1 of the first launching position 8c of first raw material projection mechanism 8.
The broken raw material of being caught by the first broken thing layer 8b of first raw material projection mechanism 8 is subjected to centrifugal force and is accelerated and throws away from the first launching position 8c, fly in the mode of describing the first projection track 11, and both allocations of the second broken thing layer 9b of second raw material of collision rotation projection mechanism 9 and by primary fragmentation.Then, broken raw material behind this primary fragmentation is throwed once more by the second launching position 9c from second raw material projection mechanism 9, depict second projection track 12 flight, collision is on the broken thing layer of the main body side 4a that forms in interior week of the upper body 2a of disintegrating machine main body 2 and by second-time breakage.Broken raw material by the second-time breakage manufacturing falls in the lower case 2b of disintegrating machine main body 2 and the space between the rotor main shaft support unit 5, and be discharged to outside the system from the crushed product outlet 2c of the lower side opening of lower case 2b, as crushed product for use.
According to the vertical offcenter crusher 1 of present embodiment one, as mentioned above, broken raw material is by the second broken thing layer 9b primary fragmentation, and the broken raw material behind the primary fragmentation is by the broken thing layer of main body side 4a second-time breakage.Owing to the whole grain of this moment of secondary when carrying out second-time breakage obtains crushed product,, can obtain by the crushed product of further whole grain so compare with the situation of primary fragmentation, whole grain.In addition, compacter and simple in structure because rotor 7 is one than the vertical offcenter crusher of conventional example 1 or 2, so favourable for the cost of vertical offcenter crusher 1 self.In addition, the balance adjustment of rotor is also carried out easily, so the upkeep operation required time is shorter, thereby also favourable for the maintenance cost of vertical offcenter crusher 1 self.Have, the peripheral speed of the first launching position 8c is a fair speed again, and broken raw material can be partial to the part on the shock surface of second raw material projection mechanism 9, thus the flight path of broken raw material can not disperse, thereby can be efficiently with broken raw material fragmentation.
In addition, under the situation of the vertical offcenter crusher 1 of present embodiment one, the second broken thing layer 9b that will continue regeneration with second raw material projection mechanism 9 from the broken raw material of the first launching position 8c projection of first raw material projection mechanism 8 carry out fragmentation and whole.Therefore, can as the vertical offcenter crusher of conventional example 3, not wear and tear by the metal impingement area that impacts son, so the running stores expense can not increase.
In addition, the rotor 7 of the vertical offcenter crusher 1 of present embodiment one is by speed setting mechanism and Motor Drive, it is more than the 20m/s that its rotary speed makes the peripheral speed V1 at the first launching position 8c place of the raw material projection mechanism 8 that wins, so broken raw material disperses to the above-below direction of the first launching position 8c of first raw material projection mechanism 8, makes by the raw material bed thickness of the first launching position 8c even.Therefore, the projection stability-of-path of broken raw material, thus suppressed the diffusion of broken raw material, so can make broken raw material collide both allocations of second raw material projection mechanism 9.Therefore, can as conventional example 4, not cause preparing the guide surface of guide member, the guide surface eccentric wear damage of guide member, so the running stores expense can not increase.
The vertical offcenter crusher of the embodiment of the present invention two of the method for operation of implementing vertical offcenter crusher of the present invention then, is described with reference to accompanying drawing successively.Fig. 4 is the sectional elevation of rotor of the vertical offcenter crusher of embodiment of the present invention two, and Fig. 5 is the longitudinal section of rotor of the vertical offcenter crusher of embodiment of the present invention two.Wherein, because embodiment of the present invention two is that with above-mentioned embodiment one difference the structure of second raw material projection mechanism is different, other structure is all identical with above-mentioned embodiment one, so same section is marked with same reference numerals, mainly its difference is described.
Promptly, the rotor 7 of the vertical offcenter crusher of present embodiment two can be understood in the comparison that relatively reaches Fig. 3 and Fig. 5 of Fig. 2 and Fig. 4 well, and second raw material projection mechanism 9 of the rotor 7 of the vertical offcenter crusher of present embodiment two is made of the fragmentation projection plate of tabular hard material system.In addition, the shock surface of second raw material of above-mentioned embodiment one projection mechanism 9 towards setting for, from this shock surface of broken raw material approximate right angle ground collision of first launching position projection of first raw material projection mechanism 8.Relative with it, the shock surface of second raw material of present embodiment two projection mechanism 9 towards setting for, collide this shock surface from the broken raw material of first launching position projection of first raw material projection mechanism 8 from incline direction.
It is the reasons are as follows, promptly, second raw material of present embodiment two projection mechanism 9 is fragmentation projection plates of tabular hard material system, and the shock surface that is the second broken thing layer except than second raw material projection mechanism 9 of above-mentioned embodiment one also are easy to skid outside bounce is stronger.Therefore, with the shock surface of second raw material projection mechanism 9 towards be set at the shock surface of second raw material projection mechanism 9 of above-mentioned embodiment one when identical, can not be from second raw material projection mechanism 9 to throw along the mode of the suitable broken thing layer of direction collision main body side.Have, the hard material as constituting second raw material projection mechanism 9 for example can use carbide alloy again.
Therefore, only different on the structure of second raw material projection mechanism according to the vertical offcenter crusher of present embodiment two with the vertical offcenter crusher of above-mentioned embodiment one, so can obtain the effect equal with above-mentioned embodiment one.In addition, the fragmentation projection plate of the tabular hard material system of second raw material projection mechanism 9 is running stores, so compare with the vertical offcenter crusher of above-mentioned embodiment one aspect the running stores expense comparatively unfavorable, but can be more effectively with broken raw material fragmentation, then use the whole grain of the broken thing layer of main body side 4a again, so can make more efficiently through once and more excellent on by this aspect of crushed product of whole grain than the vertical offcenter crusher of above-mentioned embodiment one by rotor 7.
Have, the neither mistake of vertical offcenter crusher of above-mentioned embodiment one, two is instantiations of the present invention again.Therefore, be not the form that limits vertical offcenter crusher of the present invention by the scheme of above-mentioned embodiment one, two, in the scope that does not break away from technological thought of the present invention, can freely carry out design variation etc.For example, be 2,3,5 or 6 etc. (just) even make raw material input port number even the quantity of first raw material projection mechanism 8 or second raw material projection mechanism 9 is increased or reduces, it is also identical with above-mentioned embodiment with the effect of the whole grain of secondary to obtain second-time breakage.In addition, making projection progression is more than 3, can obtain the better effect of broken or whole grain.
