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.Grinding Rollers: Grinding roller is the main part for crushing and grinding materials. The grinding roller is composed of cast steel roller sleeve, forging shaft and wear-resistant surfacing bushing. The grinding roller is installed on the rocker arm of the cement vertical roller mill, under the action of external force, it is pressed tightly on the material of What is a vertical roller mill(VRM)?
