### 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. The % loading or change volume can then be read off the graph below or ...

### CALCULATION OF THE GRINDING BALLS ASSORTMENT

21/10/2020  The calculation of the average diameter of the grinding ball in the mill showed that it is necessary to use 23.74mm steel grinding balls for maximum effective grinding. Knowing that the loading rate is 13-15 tons, we have determined the range of the grinding balls assortment: 11 tons of 25 mm balls and 2 tons of 30 mm balls. Next (as the grinding balls wear out), the mill needs to be refilled ...

### Ball Mill Motor Power Draw Sizing and Design Formula

The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S. ﻿﻿ Rod and Ball Mills by C.A. Rowland and D.M. Kjos @ Allis-Chalmers
