Zirconia grinding medium ball is a hard and inert material used in ball mills for fine grinding of food, molds, paints, pigments, and minerals. The size range of the grinding medium ball is 0.6mm-50mm. Grinding media are used for the particle size reduction process of minerals, dyes, pigments, cement, paints and printing inks, cement coatings, etc. These balls are very suitable for grinding and have the best performance level.

3 . Advantages:
Compared with traditional ball mill grinding media such as alumina balls, zirconium silicate balls, steel balls, and glass beads, zirconia grinding media (Y-TZP grinding media) have the characteristics of high density, high hardness, and high fracture toughness, making them have higher grinding efficiency than traditional grinding media, which can protect materials from pollution and prevent chemical corrosion.
The Ra of 95 zirconia balls is less than 0.2 μ m, the surface is smooth, and the residue is less than 0.01%. In the explosion of titanium dioxide in cosmetics, it can be washed three times with water to completely remove the residue on the surface of the beads. In the pharmaceutical field, CIP So, GMP zirconium ion solution dosage, and ibprofen raw materials meet the standards after<0.1, and the ppm of the cleaning system is cleaned through lubrication combination. A smooth surface can reduce frictional resistance and energy loss during sandblasting, especially when continuously blasting high viscosity materials.
