• Detailed Description:

  Corundum and corundum-mullite AL2O3 porcelain balls and porcelain lining bricks are most suitable to be used as grinding media and drum linging of various grinding equipments because of its excellent properties such as high strength,high hardness,high abrasion resistance, high gravity, small size,high temperature resitance.
  Application: It is mainly used for non-metalmineral products extra refining, it is ideal grinding media for stirring grinding, sand grinder and vibeation grinding. And it is widely applied in ceramics, paint, ink coatings,dyes, rubber and power industries.
  
  Performance:
  1. High density and hardness,impact resistance, low loss rate, smooth surface and no contamination to products.
  2. Fine chemical stability, anti-corrosion..
  3.Under condition of appropriate ball size ration, it can achieve high grinding efficiency with material results D≤2μm.
  4.High performance and low price.
