Ball mills are used primary for single stage f ine grinding, regrinding, and as the second s tage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry
Grinding differs with the pyroprocessing process (kiln type) used. In dry processing, the materials are ground into a powder that can flow in horizontal ball mills or in vertical roller mills. In a ball mill, steelalloy balls are responsible for decreasing the size of the raw material pieces in a rotating cylinder.

slag, fly ash, pozzolanes, limestone etc.). The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments
Vertical roller mill. Vertical roller mill, also called cement vertical mill, it grinds raw materials by the movement between grinding roller, millstone and grinding device. In general the grinding efficiency of vertical roller mill is 80% as much power as cement ball mill, reduce about 30% power consumption. vertical cement mill.
The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...
