A novel approach of evaluating crushing energy in ball

The segregation of different types of balls causes uneven distribution of collision and energy in the ball mill. Based on the basic assumption that the crushing energy is related to the energy loss in ball collisions, the concept of regional total energy (or RTE, for short) is put forward to evaluate the axial inconsistent crushing effect in different areas caused by axial segregation in the drum.
