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. The typical energy use for roller mills lies within 18 to 20 kWh/t clinker, depending on cement fineness. In 2002, Phoenix Cement Company installed the first vertical roller mill used for cement ...Get Price
