Zirconia grinding beads, a kind of ceramic grinding media, have features of good quality, no fracture, stable performance, reliable quality and long service life. They're low comprehensive operating cost which can effectively ensure that the abrasive material is not polluted, and maintain the high purity of the abrasive material. The high density of the zirconia ceramic beads can improve the grinding efficiency. And due to the low wear rate of zirconia mill balls, the stability of the grinding process condition can be effectively ensured. The stability and consistency of the quality of the raw material facilitates process control and management.
Besides Zirconium grinding balls , ceramic grinding cylinder , 92% 95% Al2O3 High alumina grinding ceramic balls can be offered .
