Experiment Part A: Ball Milling - Blogger
Different specification steel balls are installed on the scale board in the ball mill, when the barrel body rotates and produces centrifugal force,at this time, the steel ball is carried to some height and falls to make the material grinding and striking. The speed of rotation is the greatest important factor in the operation of the ball mill.

Mill Steel Charge Volume Calculation
We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
