Product Introduction

Zirconium silicate ceramic balls and beads as ceramic grinding media are made from imported Australian zircon sand by using rolling into billets and sintering phase technology, sophisticated technologies provide our customers zirconium silicate grindidng medias of both high compressive strength and low abrasiveness. Compared with alumina and glass balls, zirconium silicate grinding media balls have the advantages of low abrasiveness and high toughness.
