The influence of the production method of grinding media balls o

According to research, grinding balls of the same material have large differences in wear resistance due to differences in production methods and control processes. The most typical one is alumina balls. The molding methods of alumina balls include extrusion method, agglomerate method, hydraulic hard molding method and isostatic pressing method. The reason may be that the compactness and uniformity of the former are higher than that of the latter, and a solid whole can be formed after sintering.

In addition, the alumina raw materials used by the two may also be different, and the raw material purity, particle size, powder fluidity and other aspects are different. The difference will also have a great impact on the wear resistance of the grinding media, which will eventually affect the crushing effect.
