CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

When mill diameter and mill power became again increased, only the Gearless Mill Drive (GMD) could be envisaged to cover this requirement above 10 MW. The GMD is by its nature a variable speed drive system. Process operators, once having the facility of adjustable speed, could not live anymore without it for SAG mills.

The minus 152 mm (6 in) product is conveyed onto a 29,940 Mt (33,000 st) crushed ore stockpile, reclaimed by three vibrating feeders, and then conveyed to the SAG feed chute at a targeted rate of 136 Mt/hr (150 st/hr). The control strategy for the SAG mill is fairly basic. Parameters which can be adjusted are feed tons per hour and mill speed.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
