High Alumina Grinding Balls

1.High density grinding balls 2.High harness 3.High alumina purity 4.Low wear lost 5.High resistance to acid and alkali

 High 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
