1. Product Description
Zirconium silicate ceramic balls and beads as ceramic grinding media which are made fromgood quality zircon sand by sintering technology. We provide our customers zirconium silicate grindidng medias of both high compressive strength and low abrasiveness. Compared with alumina and glass balls, zirconium silicate grinding media balls have the advantages of low abrasiveness and high toughness.
It has uniform and dense microcrystal structure,which is one cost-effective grinding media compared with 95 zirconia beads.

3. Features of Zirconium Silicate Beads (65 Zirconia Beads)
As ceramic grinding media, the zirconium silicate ceramic balls have the following features:
Good roundness, smooth surface；
High density and high strength；
Good stability, resistant to acid and alkali;
Excellent toughness, compressive strength, impace resistance, unbreakable;
Low wear loss, friendly to the grinding machines.
Compared with 95 Yttrium stabilized zirconia beads, 65 zirconia beads has the features of lower density,which is suitable for grinding of low and medium viscosity slurry. What's more, it is cheaper than 95 zirconia beads in price.
4. Applications of 65 Zirconia Beads Ceramic Grinding Media
65 zirconium silicate beads can be used for material grinding, polishing abrasives, sand mills, stirring mills, vibration polishing machine, eddy current machines.
As ceramic grinding media, it is widely used in medium-hard particles' dispersion and grinding in the paste whose viscosity ranges from low to medium.
They also be used in superfine grinding of calcium carbonate, kaolin, titanium dioxide, pesticides, coatings, paints.
