Factors affecting the wear resistance of alumina grinding balls

Alumina grinding ball is also called high alumina ceramic ball stone,alumina wear ball,inert alumina ball.The production process adopts isostatic pressing,and some small balls adopt artificial ball method; the raw material uses calcined alumina powder,which has strong wear resistance,improves the stability of the product,and reduces the surface wear; the calcination temperature of the product reaches 1600 ℃ or higher ,Holding time exceeds 10 hours.

Alumina grinding ball has the characteristics of high hardness,high density,small abrasion,smooth surface and corrosion resistance.It is an ideal anti-wear grinding medium for grinding glazes,billets and various powder materials.Used in industries such as ceramics,cement,coatings,refractory materials,inorganic mineral powders,ball mill lining and grinding media.

Alumina grinding ball is an important grinding medium in the grinding industry market,and it is also a higher grinding medium in the grinding material of ball mill.The alumina grinding ball is undoubtedly better in grinding and wear resistance,so what are the factors that affect the alumina grinding ball?

Selecting the raw material Al2O3 is very important for alumina grinding balls.The choice of Al2O3 directly affects the final product quality and grinding performance of alumina balls.The particle size of Al2O3 raw material will also directly affect the wear resistance of alumina grinding balls.

Choose the appropriate sintering aid,reduce the sintering temperature of the alumina grinding ball through the sintering aid,thereby improving the ceramic microstructure and the mechanical properties of the alumina grinding ball,and then improve the wear resistance of the alumina grinding ball.
