Jan 04, 2012 · As a result, mills are seldom run with charge levels greater than 45%. In rod mills, the charge is swollen by particles of feed which separate the rods. If the mill is shut down immediately after the feed is shut off, the charge level will be greater than if the mill had been "ground out" prior to shutdown. . Ball mill is widely used in .
by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill, and the water is . while maintaining particle size at existing levels. Prior to automation of the process as described below the . Grinding control strategy on the conventional milling circuit With the increase in ratio set point, a decrease in Cyclone 1 .
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.
