When grinding cement, the ball mill has a yield of 300~1000g/t, and the grinding system of the roller press has a yield of 0.5g/t, so it can meet the requirements of white cement. Low noise. The ball mill noise is above 110 dB, while the roller press is about 80 dB.
1.. IntroductionSchönert (1979) has shown that the most energy efficient method of comminuting particles is to compress them between the two plates. Compressing a particle bed between two counter rotating rolls was achieved by the invention of the high pressure grinding rolls (HPGR) (Schönert and Knobloch, 1984).The first commercial application of HPGR was in 1985 and its success …
Roll Press Machine For Cement Grinding. As skewing starts to occur in the floating roll the asc system adjusts the press force applied to the hydraulic cylinders keeping the roll assemblies as near parallel as possible during operation while at the same time maintaining interparticle contact and grinding efficiency over the roll width differing frame types for specific applications.
Cement grinding. The clinker from the pyro-processing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface (cm2/gm).
