1. Cylindrical Shell: The ball mill consists of a hollow cylindrical shell that rotates about its axis. The shell is usually made of steel, stainless steel, or rubber. 2. Liners: An abrasion-resistant material such as manganese steel or rubber typically lines the inner surface of the cylindrical shell to protect it from wear due to the grinding action.

Larger balls are heavier and will be able to crush harder materials, but with less strikes per revolution, they will mill slower. Particle size. Ball milling has been used to grind materials to average particle sizes of 20 nanometres and finer, with extended milling time continuing to reduce particle size but with diminishing returns.
- Motor Power: The motor power of a ball mill is an important factor in determining its grinding capacity. Ball mills can be equipped with motors ranging from 10 kW to 500 kW or more, depending on the size and desired output of the mill. - Speed: Ball mills are usually operated at speeds between 60% and 70% of the critical speed.

What is a ball mill? A ball mill is a size reduction or milling equipment which uses two grinding mechanisms, namely, impact and shear. 1 Unlike other size reduction equipment, such as breakers and jaw crushers, ball mills are capable of producing powders and particulate materials of mean particle sizes within the 750 to 50 micron (µm) range.

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.
