Experimental study of charge dynamics in a laboratory
The toe angle was inversely proportional to ball filling but the impact point angle was appeared to invariant to ball filling and inversely proportional to mill speed. By means of motion analysis of the charge a good grinding efficiency can be obtained when the ball filling ranging from 20 to 40 and the mill speed ranging from 70 to 80 .

Keeping an eye out for grinding mill dropped charge and
Horizontal grinding mills are typically used to break and grind rocks that contain minerals. To help the grinding process water and steel balls are added to the process which then form the charge in the mill. Ball mill charge contains a significant amount of steel balls and can become extremely heavy.

Effect of Grinding Media on Milling911 Metallurgist
Effect of Balls Hardness on Rate of Grinding Tests by Coghill and Devaney show that the hardness of the balls has some effect upon the rate of grinding in mill. These results are plotted in Fig. 6.8a and it is seen that both for dolomite and chert there is an increase in the rate of grinding with increasing hardness of ball.
