Features
1. High strength, excellent wear resistance, 20 times more than commonly ceramic ball of France or ceramic ball, keep the material high degree of purity.
2. High density, high grinding efficiency, shorten 50% grinding times.
3. Very good roundness, very smooth and shiny surface, longer using life.
Advantages
Compared with natural stone balls and normal ceramic balls, alumina grinding ball
increases by 20-40 times in its performance of wear resistance.
Its grinding efficiency improves by 40%-60% and ball mill efficiency add by 30%-40%.
Their total costs only take 40-60 percent of that of natural stone balls.
Inert Alumina Ball are the most widely used support media in the world because of their excellent consistence and reliability. Products to these specifications are manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalyst.
