Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 120mm according to different grinding requirements. In a cement ball mill, generally, φ50–100mm steel balls are used in the coarse grinding chamber, φ20–50mm steel balls are used in the fine grinding chamber. 2.

Magotteaux determines the optimum design and alloy for cement mill liners to give the best mill protection. This is done according to a variety of factors such as shell liner type, rotation speed, maximum ball diameter, grinding media filling degree, material ground and mill drilling. The key benefits of this include an increased lifetime, a ...

Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5–8 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer ...

Grinding mills are size reductions machines that often follow crushers in the processes where finer products are desired after crushing. Different grinding machines are usually named as mills, for example rod mills, ball mills, and attrition mills. Because of the name, verb milling is also been used as a synonym for grinding.
