Feb 13, 2017 · 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.

Special design to ball mill which will be selected on the basis of material’s hardness, grindability index, final particle size and capacity. The shape of the lining and the ball (segment) are tailored according to years of engineering practice experience to maximize the grinding efficiency of the ball mill and reduce the energy consumption.

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges ...
