It is the equipment for crushing and grinding the raw material. The rollers are made of the wearable iron and alloy steel which can reach to the hardness value of HRC60o~62^o, HRC48o~55o after being quenched . Over the roller there is a material’s distributor which not only brings roller’s fragmentation effect into full play but also improve the fineness and yield of crushed materials. And it can escape from the phenomenon of the middle slot .
