recently-constructed cement plant is given with recommen-dations on proposed structural arrangement. A roller press is installed in front of grinding installations to cut down energy consumption in the grinding unit. Installa-tion of a roller press before rolling mill or cement mill in cement plants is now becoming a common feature.

Roller press install for pre-grinding before cement ball mill

Why install Roller Press in Cement Manufacturing Plant. The overall trend is to increase the capacity of pre-grinding bed, and transfer 60% to 70% of of the ball mill functions section to it and high fine airflow classification equipment to complete the system, with a large range of increased production and power saving capacity. For example, the particle sizes of the grinding materials can be less than 200 μm or

The fixed roller is supported directly on the press frame, while the so-called floating roller is supported in the frame by a hydro-pneumatic spring. The movement of the floating roller constitutes the basic principle of a roller press. The extent of the roller movement (roller gap) is a function of the pressing force generated by the hydraulic system in relation to the reaction forces exerted
