When they move across the grinding zone, they will get grinded by the rollers. The materials in the air flow will go through the rotor vanes on the separator above. The coarse powder will go back to the millstone while the eligible powder will go out of the mill together with the air flow and get collected by the powder collector.
D2.5 Where G is capacity of the mill K1 is coefficient, which is relevant to the typer of roller mill, the selected and used pressure, the performance of grinded material. Different specification of roller mill, so the K1 is different. K1 of Loesche Mills series roller mill is 9.6 and for Atox mills it is 7 and for MPS mills
Apr 13, 2020 The crushed materials of the Raymond mill are mainly rolled by the grinding roller. If the grinding roller is worn for a long time, it will wear. When processing materials with high hardness, it is easy to cause abrasion on the grinding roller when the material grinded by the mill
