Slag, fly ash and slag water have become one of the important mixed material, but the grind ability of slag and other materials is poor, so it is particularly important to select the appropriate process. Joint of cement grinding process were made analysis and comparison, it is considered that the Clirik powder grinder, vertical powder grinder to do pre-grinding slag, which can improve the quality of cement, save energy, at the same time, the grinding system in the choice of grinding equipment is also very important.

`Water slag concrete has the advantage of light quality, good heat preservation performance, good sound-absorbing , and has the advantages of a certain strength and machinability, as filling of palisade structure and thermal insulation material, was widely used in construction, is paid great attention to by all countries in the world, many countries become strong promotion and development of the optimum construction materials.
 

In short, the development of cement industry, is indispensable to the vertical powder grinder field vertical mill. Material after vertical powder grinder, as cement additives can improve the strength, water proofing property, permeability resistance of concrete, and therefore is widely applied in the field of modern building materials.
