The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.

Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind.

A large ball mill is known for its large processing capacity and long daily operation time, so it is also called a large scale ball mill or large capacity ball mill. The large ball mill is especially suitable for large-scale grinding production. It adopts two bin grinding, which is more energy-saving and environmental protection.

balls (grinding media) of various sizes. During operation, cement clinker that has been baked in the rotary kiln is fed into the mill through the input shaft. The cylinder rotates at approximately 15 rpm, with the result that the clinker is ground into cement powder by the impact and friction of the grinding media. Schematic diagram of a cement

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).
