65 zirconium silicate grinding beads for ink, coating, painting and pestisides
Zirconium Silicate beads are sintered from zirconium silicate powder and formulated with strict process controls, almost free of bubbles and pores. With lower density, lower hardness and lower crush load than Zirconia beads. It is adequate for the vertical type mills in which heavy zirconia can not be used.
Zirconium Silicate beads grinding media are with the low price and high level of efficiency, available in different fractions ranging from 0.6 mm to 10 mm.
