- wear-resistant alumina ball:
Applicatiion:Mainly used for finishing and deep processing hard materials of different types of ceramics, glazes, glass and chemical factories. It is the grinding medium of ball mill, pot mill, vibration mill and other fine powder grinding equipment. Its grinding efficiency and wear resistance are much better than ordinary pebble or natural pebble.
Non-metallic mineral products powder (such as zirconium silicate, kaolin, heavy calcium carbonate, etc.) and coatings, paints and other industries of material grinding and dispersion as well as polishing of metal parts, suitable for all types of grinding and polishing equipments.
