Get PriceWe 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.

Get PriceThe effects of mill feed size reduction on wet rod grinding has been studied by Strohl [2]: when the percent passing 13 mm in the mill feed was increased from 84% to 98% in rod grinding, the fineness of ground products increased from 85% to 94% passing mm, while there was a 10% increase in mill capacity and a 15% decrease in wear of the rods.

Get PriceRod mills normally carry 35 to 65% rod charge by volume. The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill, and (2) keeping the rod charge low so rods will not work their way into discharge openings where they can cause rod tangling.

Get PriceCharge density is a measure of electric charge per unit volume of space, in one, two or three dimensions. More specifically: the linear, surface, or volume charge density is the amount of electric charge per unit length, surface area, or volume, respectively.
