QR offer two type ceramic ball .Silicon Nitride Ceramic Balls and Zirconium Oxide Ceramic Ball 

Silicon Nitride Ceramic Ball have high strength, high hardness,high wear resistance,high proportion,small volume,high temperature resistant corrosion resistance, no pollution and other excellent features. At room temperature with high stiffness, no magnetic, electrical insulation.

Applications: it is Widely used in different types of ceramic,enamel,glass,chemical industry and thick hard material finishing and deep processing of the factory.It is grinding medium of the fine crushing equipment such as ball mill,vibration mill,Cylindrical grinding machine.The crushing grinding efficiency and wear resistance significantly better than ordinary or natural pebble stone ball

Zirconium Oxide Ceramic Ball has high strength and toughness at room temperature, good wear resistance, high temperature resistance, corrosion resistance, high rigidity, non-magnetic, electrical insulation. When the zirconia ceramic ball is at 600°C, its strength and hardness are almost constant and its density is 6.00g/cm3. The thermal expansion coefficient is close to that of the metal and can be used in conjunction with metal. Suitable for bearings, seals and so on
