Basic Ball Mill Grinding Circuit

In other plants a ball- mill or a tube-mill will do all the grinding, but it must be fed with fine ore—say, 1/8 to ¼ inch—to do this properly. Grinding coarse ore in a ball-mill is done by steel balls of three sizes (5, 4, and 3 inches); fine ore is ground in a tube-mill by 2- and 1½-inch balls or by flint pebbles or by hard, rounded mine ...
