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 ...(PDF) STARTLING EFFECT OF BALL SCATS REMOVAL ON .Powell and Smit (2001) investigated the effect of removing scats from a SAG mill, however the SAG mill environment differs from that of ball mill, so it is worth assessing the impact of worn balls ...Integrated advanced process control with a sag mill .(EGL) SAG mill driven by a 24,000 kW gearless drive.
