Feature
1.High hardness,high proportion,good high temperature performance,high mechanical strength,no pollution for the material,good wear-resisting performance.
2.Matched with natural stone-ball and normal ceramic ball,it occur the property that abrasive resistance be raised to 20-40 times,grinding efficiency be raised more than 40-60%.
3.Grinding machine work efficiency be improved more than 30-40%,and the
combined cost is 40-60% of the natural stone-ball,the grinding machine working life be improved from 2 years to 6-8 years.
Application
High alumina ball is widely used in ceramics,electronics ceramics,petroleum, chemical, building materials, metallurgy, machinery,pigment,glass, glaze and many other high-grade packing and grinding media.
