### Operating and Troubleshooting a Grinding Circuit

A ball mill operates more with the grinding surface action of the balls than the impact form of grinding that the rod mill uses. Taking this into account you can see that if the rod mill doesn''t reduce the ore to a size that the ball mill can reduce quickly, the circuit load will
