zirconium silicate grinding media ceramic bead kaolin ceramic grinding beads

zirconium silicate grinding media ceramic bead kaolin ceramic grinding beads

Description:
zirconium silicate beads are made from the high grade Australian zircon sand with granulating shaped method and hardened by sintering. The unique formula and producing procedure offer you a middle density and hardness, high wear resistance zircon beads. It is a good option to grind and disperse middle hard particles in low to middle viscosity range slurries.
