1. TZP grinding media:
A,preventing material from contamination because of its extreme low wear rate.
B,high grinding efficiency
C,lower total costs due to the long using life
2. Uses: Material for grinding and dispersed, structural ceramics, electronics ceramics, refractory ceramics, magnetic material, metallurg, medicine, food, cosmetics, paints, textiles, printing and dyeing, pigment and other industries.
3. Available sizes: Sphere(Diameter):0.6,0.8,1,1.5,2,2.5,3,5,6.5,7,10,12,15,20,30,55mm etc
Cylinder(Diameter):3×3,5×5,7×7,10×10,12×12mm etc
4. Advantages:
compared with the traditional grinding medium such as alumina balls,zirconium silicate balls,steel balls,agate balls and glass pearls,the zirconia grinding medium(Y-TZP grinding medium)has high density,high hardness and high tenacity feature,which provide it higher grinding efficiency than the traditional grinding medium,high-wearing zirconia grinding medium can protect materials from pollution and guard against chemical corrosion to the useful time of grinding medium.
