Jan 06, 2017 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 1-inch balls or by flint pebbles or by hard, rounded mine rock such as quartzite. These grinding media wear to small sizes, and new ones must be added regularly to make up the weight. When a mill is in closed circuit with a classifier, it will handle a circulating load of
