In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:

1, by repeatedly broken, reduced powder rate, and reduced the damage of breaker roll simultaneously, increase the service life.

Block is set above roll, the bulk materials that charging aperture place falls can be divided into two-way and falls, reduce its impulsive force simultaneously, prevent material from directly impacting roll, reduce the damage of breaker roll, meanwhile, also can accelerate charging rate, increase work efficiency, the material fallen first carries out a roughing by roughing mills, and then carry out secondary finish rolling by mm finishing mill unit, first time roughing is mainly in order to roll for less material by bulk materials, namely pretreatment is carried out to material, protect the roll of mm finishing mill unit can not cause damage and card roller by breaker roll because material is excessive simultaneously, like this by twice rolling, its breakage rate improves, and cross the reduction of powder rate, the engagement place of baffle plate mainly in order to make material can fall into two rolls better on block both sides, make it directly to fall into material receiving port from other gaps, percentage of damage is improved further.

2, make full use of the effect of roll, improve resource utilization, reduce unnecessary waste.

Around roll, arrange a circle many hinges, the hinge above and below roll regulates the spacing of its every bar hinge by vertical roller bearing, and material can be fallen from its gap location, is unlikely to be formed the turnover of material to stop when allowing hinge pass herein; Hinge is allowed to pass in the place that roll is meshed, and allow the roller cingulum of roll move hinge upwards to walk, hinge is rotated, simultaneously, chain is stepped up by horizontal roller bearing, every bar hinge gap at two roll shop building places is narrowed, the material that is not broken or the material that is not completely broken is made to be brought into roll engagement place by rolling again by the effect of seizing on both sides by the arms of hinge, so not only take full advantage of the effect of roll rolling, also use the secondary rolling effect that it is difficult to utilize, take full advantage of the energy, improve resource utilization, reduce unnecessary waste; In order to allow the material be not broken or the material be not completely broken can be out screened and can be seized on both sides by the arms by hinge better, sieve bend bar is provided with in the below of hinge, sieve bend bar is provided with some along the direction of roll roll shaft, spacing between every root sieve bend bar is adjustable, be mainly used to collect the material be not broken or the material be not completely broken, those materials reaching pre-provisioning request then can fall into material receiving port by the gap of sieving rod member.

3, can sub-elect the material of different size, function strengthens simultaneously.

In roughing mills and mm finishing mill unit, all be provided with the roll of a pair adjustable position, by changing the relative distance of roll shop building, just fragmentation can go out different size material, the material size oneself wanted can be obtained as requested, simultaneously, required large scale material can first be screened by the screen cloth of adjustable aperture size by the material reaching pre-provisioning request, and can be collected continuously by the discharging opening of screen periphery, make production serialization, as to obtain smaller szie material this carry out further rolling by mm finishing mill unit, and then screened by screen cloth, if primary screening can not get required size size, the screen cloth of which floor different pore size size then can be set below infundibulate material receiving port more, and often screen once, just can obtain the close material of a batch size, screen so layer by layer, disintegrating machine is had concurrently the simultaneously function of separator, strengthen and with the addition of the function of disintegrating machine, make disintegrating machine adaptability stronger.

4, disintegrating machine stable working, noise is little, cost and maintenance cost low.

Block, baffle plate and screen cloth are coated with one deck there is flexible rubber coating; greatly can reduce the noise that material produces in shattering process; whole shattering process is orderly continuously; identical power is exported by two same motor; shattering process is carried out more reposefully; and; though this disintegrating machine employs eight rolls; but its operating efficiency is lower than two dual kibbler roll explicit costs; and structurally the significant components such as breaker roll is also provided with protective device; significantly improve its service life, corresponding cost and maintenance cost lower.
