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.
However, the grinding effect of the wet ball mill is significantly better than that of dry ball mill. Wet mills generally have a productivity higher than 30% of dry mills. They have higher grinding fineness and better mineral processing effect. Therefore, most of the products sold on the market are wet ball mills.
The grinding of the ball mill can be divided into two methods: dry and wet. For dry milling, the water content of the abrasive has a great influence on the output and quality of the mill. The higher the water content of the abrasive material, the more likely it is to cause full grinding or paste grinding, reducing the grinding efficiency, and ...
