Analysis of grinding kinetics in a laboratory ball mill

In general the ball mill is ground by the impact energy applied to the materials owing to the dropping of the grinding media that is moved upward by the rotation of the mill The normal force applied to the materials by the grinding media were calculated using the EDEM and can be seen from Fig 10 When the total force is checked the normal
