A ball mill is a grinding machine with grinding balls used to grind or mix materials for mineral processing, paints, fireworks, ceramics and selective laser sintering.
How a ball mill works
It works on the principle of impact and abrasion: the balls are reduced in size by impact as they fall from near the top of the shell.
A ball mill consists of a hollow cylindrical shell that rotates about its axis. The axis of the shell can be horizontal or at a small angle to the horizontal. The shell contains a portion of steel balls. The grinding media are grinding balls, which can be made of steel, stainless steel, ceramic or rubber. The inner surface of the cylindrical shell is usually lined with a wear-resistant material such as manganese steel or rubber lining. Rubber-lined mills have less wear. The length of the mill is approximately equal to its diameter.
Applications of ball mills
Ball mills are used to grind materials such as ores, coal, pigments and feldspar for pottery. Grinding can be done wet or dry, but wet grinding has lower speed. Ball mills are frequently used in scientific work to reduce particle size, eliminate agglomerates, change particle shape, perform mechanical alloying, blend, produce powders and change material properties.
