In Mineral Processing Design and Operations (Second Edition), 2016. Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of %. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.
One (1) only Steel Ball Mill, 15" diameter x 21" long, NonJacketed, complete with 1/2 HP, 110/220V integral gear motor. Total mill volume is 16 USG. Ball charge required is approx. 215 lbs, product volume approx. USG.
In some cases it has been found advantageous to add replacement media of . 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. . In ball mills .
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.

Rod Mill and Ball Mill Rod mills are grinding machine which employ high carbon steel or special steel rods of nearly the same length as that of the drum, in place of steel balls in ball mills. Rod mill products are generally coarser than those produced in a ball mill, and rod mills are well suited to handle coarser feed and to control the top size of the product.
May 11, 2016· 3slit and 4slit rolling allows production volume to be increased even with a small number of rolling mills. Slit rolling is also suitable for revamping a low productivity 2slit line mill to a high productivity mill with greater production volume while keeping the number of rolling mills the same.
