Product Description

Product Description

92% 99% Alumina Grinding Ceramic Ball 

Grinding Balls are suitable for grinding medium used in ball grinding machines.

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.

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.

Our Advantages

• An exceptionally high degree of hardness and resistance to wear.
• High compressive strength.
• Zero water absorption and porosity.
• High density alumina balls resulting in reduction of ball mill rotation time.
• Absence of undesirable impurities in the composition of materials to be ground.
• Reduced energy consumption for the above reasons.
