Ball mill is widely used in mineral processing, building materials and chemical industry as a general grinding mill equipment. It can be divided into dry and wet ball mill for two grinding ways. Ball mill can be divided into lattice-type and overflow type according to different ways of discharge. In general, direct way to improve ball mill output has 3 kinds:
1 set impact fine crusher machine in front of ball mill;
2, improve grinding system to increase the grinding efficiency;
3, add-on high efficiency separator.
Materials into Ball mill is crushed first and then to smash. Ball mill is widely used in cement, silicate products, new building materials, refractories, chemical fertilizer, black and non-ferrous metals and glass ceramics and other mineral production industries. Of various ore grindability materials for other can adapt dry or wet grinding. 3 methods mentioned above, any one kind of ball mill can greatly improve yields. Of course, if conditions permit, the factory, then supporting the use of the above 3 methods, the effect is ideal. This grinding system at home and abroad in recent years is the design trend.
Three relationships: the premise of grinding before crushing, grinding powder to ensure that after the election, the fundamental transformation of the mill. Made before the crushing mill grinding of materials into the particle size greatly reduced. Thereby reducing the grinding system load; separator efficiency, the most direct benefit to the maximum fine was promptly finished elected. Reduce the rate of cement powder product back to reduce the ball mill load; the mill renovation will improve the grinding system. Into the ground particle size is reduced, efficiency is improved by the powder. If the grinding system less efficient, affecting not only mill production, but also affect the quality of final product.
