Ball Mills

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral.

Ball milling - Digitalfire

Ball mills are slow compared to other methods of grinding, it could takes hours, for example, to grind all the particles in a clay to minus 200 mesh. In fact, if mica or other flat particles exist it may be practically impossible to grind them to minus 200, for this reason ball milling is normally done in consort with wet screening.
