The cement mill plays a very important role on getting high grinding efficiency and improving the economical effects of grinding requires. Cement mill ore factory always use have following features and applications.
1,Grate type Cement mill :As the cement mill is of high discharging speed, the dwelling time of ore is relatively shorter. The cement mill grinded ores can be transferred quickly from the cement mill to Classifier for further opearation, which is helpful for the cement mill to be compensated with more ores. Meanwhile particles of large size would not dwell long in the ball mill, which reduces over-crushing and improves productivity. Compared with the overflow type of cement mill the same specification. cement mill is applicable to single-stage coarse grinding and the first stage of two-stage cement mill grinding, and also the cement mill grinding of easily-crushing and soft ores.
2,Over-flow type cement mill: Over-flow type cement mill discharges because the hollow shaft diameter at discharging side is bigger than that in feeding side, making pulp surface of the cement mill tilts towards the discharging side. When the cement mill position of the pulp is higher than minimum bus of the discharging mouth’s diameter, the pulp will overflow the ball mill. This is none-forced discharging, so that the discharging speed is low, ores staying long in the cement mill and media’s effect is unclear. As a result, over-flow type cement mill has serious over-crushing phenomena, and the capacity is lower than the same type grate cement mill. Over - flow type cement mill is suitable for fine grinding or second –period crushing.
