Description

Rubber grinder

Technical field

The present invention relates to a kind of new-type rubber grinder, be applicable to reclaimed rubber resources domain.

Background technology

At present, micelle after the fragmentation of the rubber such as junked tire, sebific duct is generally used for reclaimed rubber industry, in addition topmost purposes is made fine glue powder exactly, surpass 40 object rubber powders and just can be called fine glue powder, can be used for modified plastics, water-repellent paint, modifying road asphalt and directly interpolation in rubber manufacture process, thus, grind rubber powder and become gradually an emerging industry.

Existing flour mill mainly by motor, belt gear, utilize movable grinding disc, hard-wired fixed millstone that main shaft that belt gear drives and end thereof install, be enclosed in the milling compartment moving, fixed millstone is outside, the compositions such as pay-off, wherein, movable grinding disc and fixed millstone are solid construction, and both have respectively pedestal separately.There are the following problems for it:

1, movable grinding disc and fixed millstone are solid construction, although guaranteed the disk body rigidity of mill, but two mills temperature in abrasive dust process is high, again because the processing of rubber powder is different from hard material, rubber flexible, and rubber To Be Protected from Heat, on the mill of high temperature, micelle can not be ground into fine powder, reason is, after elastomeric material preheating, start desulfurization, reduction, now there is plasticity characteristic, can two mills be bonded together at once, rotation operation to mill produces great resistance, paste alleged in producing grinds, not only hinder normally carrying out of producing, reduce production efficiency, increased the maintenance cost of the parts such as mill simultaneously.Existingly the cooling means of movable grinding disc and fixed millstone is also just carried out conventionally cooling to surface both, cooling effect is not good, can not fundamentally address the above problem.

2, between two mills of flour mill, to there be enough normal pressures, just can make the cutter on micelle and mill surface produce enough large frictional force, thereby micelle is levigate, in order to achieve the above object, existing flour mill is all improving and is moving as much as possible, the rigidity of fixed millstone pedestal separately, but owing to will being convenient to dismantle mill, be convenient to powder delivery, powder storehouse needs the reasons such as cooling, flour mill two mills can not keep the necessary depth of parallelism under long-term duty, be easy to cause eccentric wear, greatly shortened the service life of mill, cause the particle size range of product to distribute wide simultaneously, product percent of pass is low.

3, in order to reach high-yield and high-efficiency object, conventionally adopt high power motor, but when high power motor drives main shaft High Rotation Speed by belt pulley, the larger tension force producing when belt pulley is rotated simultaneously pass to main shaft and on movable grinding disc, greatly reduce the running accuracy of movable grinding disc, have a strong impact on the qualification rate of product.
