A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
The Copper Mountain ball mills are 7315 mm24 feetin diameter and 12040 mm39.5 feetlong. They are overflow discharge ball mills with inside diameters of 7315 mm24 feetand grinding lengths of 11887 mm39 feet . Each Ball mill is also driven by two 8,500 horsepower ABB motors.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
Ball MillandDischarge Trommel. Grate Discharge Ball Mill . For closed grinding circuits producing typical ball mill products, indirect and direct on-line measurements of the product size are available. The indirect means are those which assume that the product size is relatively constant when the feed condition to the classifying unit and the operating conditions in the c
BALL MILLS . Grinding of materials in a tumbling mill with the presence of metallic balls or other media dates to the late 1800& 39;s. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media
