Principle 1：More Crushing and Less Grinding. Crushing is mainly realized by the crushing equipment's extrusion and impact on the material. While grinding mainly depends on the impact, milling and denudation of the grinding equipment. There into, grinding is an operation with low efficiency and high energy consumption.

It is defined as the volume that is occupied by the grinding media out of the total volume of the ball mill without ore or water in it. The ball load should be such that it is slightly more than 30% of the total volume of the ball mill. During general operation media occupy between 30-50% of the volume of the mill.
