Feb 13, 2017 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.
It also acts as a grinding medium. The noise of ball mill is 12-15 dB lower than that of steel-manganese liner, which reduces ball consumption by 8-10, improves the working environment of module and reduces the cost of ball consumption. 4The magnetic lining has fewer faults, and the magnetic lining plate does not need to be repaired.
