7 // Almost any plant for the grinding of cement raw material is a combination of machines specially adapted to the particular physical properties of the material to be ground. As a result, our plants work efficiently without any trouble. » Highly efficient grinding, drying, and separating in one unit » Outstanding production capacities exceeding 1,400 t/h in one single mill

Cement ball mill is a main cement grinding mill with a low energy utilization rate (only 3%-5%). Compared with the grinding energy consumption, most of its energy is consumed by collision heating and noise. Therefore, we usually adopt the cement roller press to replace the fine crushing and coarse grinding role of the ball mill.

Roller mills are operated with throughput capacities of more than 300 t/h of cement raw mix (Loesche mill, Polysius® double roller mill, Pfeiffer® MPS mill).
