Ball Mills
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.

Particle Size Distribution of Grinding Mill Products
The ball load was 455 stainless steel balls one inch in diameter, having a total weight of 30 kg. The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions.

Ball Mill | Mining Grinding Mill
Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or large-scale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.

Advances in screening technology in the mining sector
The circulating quantities are not only dependent on the screening efficiency, but also on the quantity of oversize produced by the mill. At a screening efficiency of 100 % and 35 % oversize produced by the mill, the circulating load factor is already 1.54. At 70 % screening efficiency, the circulating load factor increases to 2.
