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.
