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.

5. Ball milling is a method of production of nano materials. This process is used in producing metallic and ceramic nano materials. These mills are equipped with grinding media composed of wolfram carbide or steel. Ball mills rotate around a horizontal axis,partially filled with the material to be ground plus the grinding medium.

The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the ball mill machine. The larger the diameter is, the slower the rotation is. If the peripheral speed of the ball grinding mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill.
