Alumina Grinding Ball

 

Our RP-G alumina grinding balls are widely used in industries of ceramics, glass, porcelain enamel, pigment, chemicals, etc.

They are suitable for applications for ball mill, sand mill, pot mill librating mill and other fine breaking plants.

 

Advantages

1. high wear-resistance

The alumina balls’ wear-resistance is higher than the common alumina balls’. When it is working, the ball won’t pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.

2. high density

The high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.

 

Available Sizes:10mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 60mm, 70mm, 80mm.
