Ceramic grinding balls can be divided into medium aluminum balls, medium high aluminum balls and high aluminum balls according to different alumina contents. High-alumina balls have excellent properties such as high strength, high hardness, high wear resistance, large specific gravity, small size, high temperature resistance, corrosion resistance, and no pollution. They are widely used in different types of ceramics, enamels, glass, chemical, etc.
1.High density
2.High Strength
3.Good toughness
4.High grinding efficiency
For the ceramics.
For the glaze, paint, coating
For the zirconia silicate ,aluminum oxide ,quartz ,silicon carbide etc.
For kaolin , titanium oxide ,mining's etc.
