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

Mill Charge an overview ScienceDirect Topics

The efficiency of a ball mill depends on the number of contact points between the balls • There is a limit of ball diameter below which centrifuging of mill charge occurs; this limit can only be overcome by a change in the manner of ball movement • In sandmills, the grinding charge is driven by an impeller. Sand used in such mills has a
