VRM to Crown operations cemnet

The basic structure of a VRM for cement grinding is the same as for raw material and coal grinding. Raw materials (such as clinker, slag, fly ash, gypsum, limestone or pozzolana) are fed into the mill and ground by compression and shearing forces between the grinding table and two or four hydraulically-controlled rollers.
