Corundum and  corundum-mullite AL2O3 porcelain balls and porcelain lining bricks are morst  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

 tempe Corundum and  corundum-mullite AL2O3 porcelain balls and porcelain balls and porcelain balls  and

 porcelain lining  bricks are widely applicable to glaze、pigment  ceramics、porcelain enamel、glass、refinery、

 Printing and  dyeing and other chenical manufacture industries

Ceramic Ball Use

 High performance  abrasion resistance alumina

 micro bead is  mainly used for non-metalmineral

 products  extrarefining.If in the ideal grinding media for

 Stirring grinding、sand grinder and vibeation grinding.It

 is widely applied  in ceramics paint、ink、coatings、dyes、
rubber and power  industries

Ceramic Ball Performance

 High density and  hardness、impact resistance、low loss rate、smooth  surface

 and  nocontamination to product

 Fine chemical  stability、anti-corrosion、no pollution to the grinded products.

 Under condition of  appropriate ball size rotio  it can  achieve high grinding
effciency with  material risults D<=2

This product is a  grinding body used in ball mill、pot mill、vibrating  mill and otherfine grinding plants  it  has advantages of high hardness  high  volumetric density and anticorrosion With thesmashing effciency and scuff-resistance  much better than the of common ball-stone or natural cobbestone  it is widely used in ceramics、glass、procelain enamel、pigment、chemicals  and other trade

Ceramic Ball Wear Test methods
7 liters of  polyurethane standard ground tanks, loading 4kg ball, 4kg  water at 80 rev / min mill 24 hours, before grinding to M g dry weight, dry  weight after grinding M1 grams, since the wear of [(M-M1) / 24M]*1000
