### AMIT 135 Lesson 6 Grinding CircuitMining Mill Operator

The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill.

### The working principle of ball millMeetyou Carbide
