Operating principle of Hydraulic Roller Press . The feed material (cement clinker, slag or other cement raw material) is supplied to the roller press through inlet and here it is directed down between the two rollers which rotate against each other. At the same time, the movable roller is forced towards stationary roller at a fixed hydraulic ...

Vertical Roller Mills (VRM). Roller press with Ball mill. Ball Mill. Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.

roller size of 2.2 m with an installed motor power of 3400 kW, which is 2380 kW absorbable power, limiting production of a 3600 Blaine OPC cement to around 140 tph. For the cement quality of a roller press fi nish-grinding system, studies show that for a standard type cement compared to VRM or ball mill, no differences could be observed.

CLINKER GRINDING AND CEMENT PACKING. Roller press with ball mill is used to grind the clinker. 3.5 to 4% Gypsum is added to make OPC. To make PPC, up to 35 % fly ash is added to the clinker in addition to Gypsum. Three grades of cement (OPC 43, 53 and PPC) are manufactured and stored in silos.
