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.
These terms must not be confused with differential grinding, which has to do with the relative grinding rates of two or more minerals in an ore. Rod Mills = Selective Grinding. Ball Mills = Non-Selective Grinding. Large Balls & Small Rods Compared. Is it better to use a grinding mill with large balls or will small rods?
