The cement roller press is a type of material-crushing machine which is often used in cement plants. It usually works together with a ball mill to form a pre-grinding or final-grinding system for the grinding of raw materials, coal, and clinker. Compared with the traditional tube mill and ball mill, the roller press has lower energy consumption ...
