The relationship between ball mill efficiency and gradation

1. The steel balls must have sufficient impact force to enable the ball mill steel balls to have sufficient energy to crush the granular materials.

2. Secondly, the steel balls must have sufficient impact times on the materials. This is related to the filling rate of the steel balls and the average ball diameter. When the filling volume is constant, under the premise of ensuring sufficient impact force, try to reduce the diameter of the grinding media and increase the number of steel balls to increase the impact times on the materials, in order to improve the crushing efficiency.

3. The materials in the mill have sufficient residence time to ensure that the materials are fully crushed.
