    VRM to Crown operations - International Cement Review

    Aug 18, 2020 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

    In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table. The energy input to the material during one passage between grinding rollers and grinding track is relatively low. The thick-ness of the material bed between roller and table is a multiple of the particle size
