A ball mill consists of a cylinder, which is filled with 3035% of its volume by small steel balls and is rotated through motor. When the cylinder starts to rotate, the balls start to lift under centrifugal and frictional forces and fall back into the cylinder and onto the feed as gravitational pull exceeds those forces (Fig. ).

Overview of Ball Mill Ball mill, also known as tumbling or pebble mill is milling equipment that encompasses cylindercontaining balls and is mounted on a metallic frame that can be rotated along with a longitudinal axis. The large ball tends to break down coarse feed materials and the small ball mill to form fine products by reducing void spaces.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
