It also produces more fine particles than the jaw crusher because it crushes mortar and aggregate particles alike; in contrast, a jaw crusher only breaks a small proportion of the original aggregate, thus generating almost half the amount of fine particles for the same maximum size of particle [10,75,76]. These points are in clear favor of the ...

Typically, a hopper is used to hold and feed the rock to the mill. The rock is either gravity fed or a conveyor is used to feed the crusher. Once in the crusher, the material is broken down using a breaker plate and grinding chamber. The reduced rock exits the crusher via a conveyor belt or is discharged into a hopper.
