Roller Mill SpringerLink
Roller mill is a type of grinding equipment for crushing materials by pressure between two or more rolling surfaces or between rolling grinding bodies (balls, rollers) and a track (plane, ring, and table). The roller mill with several grinding rollers as working components rolls along the grinding ring or the grinding table to crush theThe 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.Energy-Efficient Technologies in Cement Grinding IntechOpen
