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.
