Cement production involves grinding clinker, cement, and other additives to produce slurry or mortar. The steel ball liners are typically made from forged steel fixed onto a plurality of nuts after being machined with an improved surface roughness to improve wear resistance and corrosion protection.

In the conventional process of cement production, 30–80 kWh/t specific energy is consumed in cement grinding which equals 30 % of the total energy consumption. Furthermore, approximately 60–70 % of the total electrical energy used in a cement plant is utilized for the grinding of raw materials, coal, and clinker.

Clinker grinding refers the method that material is grinded into fine powder under external force, impact, extrusion, and grinding effect. On the one hand, clinker grinding could be the last step during the cement production process. So the cement grinding method control is directly related to the cement item good quality, yield, and expense.
