In some plants a ball-mill or rod-mill will reduce the ore to, say, 100 mesh and a tube-mill will finish the grinding to 200 mesh or finer. 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 ...
