Mill Steel Charge Volume Calculation

2015-6-19  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.

THE OPTIMAL BALL DIAMETER IN A MILL

2012-5-15  Let us look back at the optimal ball charge in a mill. The necessary number of balls having the definite diameter N b in a mill should be proportional to grain number N having the definite diameters which they can grind: N b ~ N. (7) The number of grains of the material with determined diameters depends on the grain size distribution.

Mill Charge an overview ScienceDirect Topics

It is noted that further increasing this weight ratio leads to the formation of crystalline phases and this might be related to the high kinetic energy of the ball mill charge which is transformed into heat. When the W b:W p ratio was reduced to 12:1, however, the amorphization reaction was not completed. This indicates that the kinetic energy of the mill charge is insufficient for complete transition from the
