Mill Steel Charge Volume Calculation. Jun 19, 2015 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

Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell.

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation.
