Roller presses have proven to be a popular option for new and old cement plants in recent years. When used in a production line upgrade with a ball mill, they increase throughput and energy efficiency. Roller presses compact the material through two horizontal rolls.
in line 1 and two Roller press+closed circuit ball mill in line 2) based on the type of cement to be produced keeping the quality of cement equal or above the required standard. For instance (Clinker+Pozzolana+Gypsum) are proportioned and milled to produce PPC type of cement, (Clinker+Gypsum) to Produce OPC type of Cement,
Moreover, the materials are generally milled on the grinding disc by several grinding rolls repeatedly. From this point of view, the vertical mill is better than the roller press. 3.

The roller press is often used where energy-efficient grinding of large product quantities is required. The two rollers, rotating in opposite directions, exert very high pressure on the material, effectively crushing and weakening the particles (microscopic cracks), so that the subsequent fine grinding is easier.
