Coal Mill in Cement Plant Vertical Roller Mill & Air-Swept Ball Mill

Coal Mill in Cement Plant. A coal mill is also called a coal pulverizer or coal grinder. It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are air-swept ball mills and vertical roller mills.The role of coal in the cement/concrete industries is illustrated in Fig.15.1 and can be summarised as follows: • Fuel for rotary cement kilns; • Coal derived power Coal utilisation in the cement and concrete industries

Coal and its application in the cement production process

According to calculations, a large amount of energy from coal is used to produce cement, of which it takes about 200 kg of coal to produce one ton of cement and about 300-400 kg of cement to produce one cubic meter of concrete. In addition to being a fuel, industrial coal also contributes to being one of the raw materials involved in the Cement has hydraulic properties like slaked lime and hardens when mixed with water.

Energy-Efficient Technologies in Cement Grinding IntechOpen

The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.cement. Hence, one grinding compartment will generally suffice. For a coal mill, we usually recommend a light classifying liners and for raw mills we recommend heavy classifying liners.
