Ball mill A ball mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, and ceramics. Ball mill Description A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.
A ball mill can grind raw materials in two ways: dry or wet grinding. It's important to mention that two types of ball mills stand out on the market. That's the grate type and the overfall ball mill. This classification is made depending on how the materials are discharged through the mill. Design. The design is pretty simple.
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.
