Alumina ball 1.Density>3.62g/cm3 2.Wear lost<0.009 % 3.Size range:1.5mm ~70mm 4.Manufactory type:CIP or Rolling

- HIGHER DENSITY - HIGHER HARDNESS - HIGH WEAR RESISTANCE - HIGH GRINDING EFFICIENCY

    

Alumina grinding balls have characteristics of high strength, high density, high abrasion, entire specification,strong practicability. It can be used for ball mill, mixing mill, vibration mill, sand mill, etc. The products are widely used in construction ceramics, sanitary ceramics, kaolins, refractory materials, paints, coatings and other fields.

    Normal size range: Diameter 20mm,25mm,30mm,40mm,50mm,60mm,70mm.
