  • Mill Steel Charge Volume Calculation - Mineral Processing

    2019-11-22  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.

  • how to estimate the wear rate for Ball mill - Page 1 of 10

    2009-12-08  Re: how to estimate the wear rate for Ball mill. Hey; Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.
