A grinding plant comprising a highpressure roller press for crushing raw material into fragments a static cascade sifter for shifting the fragments from the highpressure roller press into fine fragments and coarse fragments, the coarse fragments being returned to the highpressure roller press and a separator for separating the fine fragments from the static cascade sifter into fine
grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.
The roller press is often used where energyefficient 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.

The Cylinder mill, commonly known as the Roller Press works by crushing the material between two cylinders kept under pressure by a hydraulic system 2 to 10 Tlinear cm. This mill uses a patented process of pulsating pressure that reduces the level of vibration and contributes in reducing energy requirements and prolonging the service life of
The roller press is a highly efficient and energysaving choice for grinding hard and medium hard materials. It is widely used in manufacturing andor processing of raw meal, cement, slag nonferrous metals and iron ore. When upgrading the capacity of ball mill systems, it is the best choice of equipment.
