Basic Ball Mill Grinding Circuit
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 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 …

Ball Mills - Mineral Processing & Metallurgy
Ball Mill Grinding Circuit. Even though many ores require fine grinding for maximum recovery, most ores liberate a large percentage of the minerals during the first pass through the grinding unit. Thus, if the free minerals can be immediately removed from the ball mill classifier circuit, there is little chance for overgrinding.
Ball Mill Design/Power Calculation
Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps ...
