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
