Analysis on the grinding operation condition of ball mill

The ball mill and the rod mill are the most commonly used grinding equipment in the dressing plant so what is the difference between the operation of the two grinding equipment? Sometimes we think why do we have a ball mill for a dressing plant but with a rod mill why? Today we analyze the problem from the point of view of the operation to
