High Strength Alumina Ceramic Grinding Ball
Ceramic grinding balls are broadly utilized as covering and supporting mterials of catalysts in reaction vessels
and as packing in towers.They are widely used in petrolem chemical , fertilizer , natural gas and environmental protection industry. With stable chemical features and a low rate of water absorption,they can resist high temp
and high pressure,and also can resist the corrosion of acid,alkali and some other organic solvents,and can
stand the change in temperature during the application.Ceramic balls can increase the distribution spots of gas
or liquid, and to support and protect the activating catalyst with low strength.
