Zirconium silicate grinding beads


ZsBeads are sintered zirconium silicate grinding beads with a high sphericity. In contrast to grinding beads that are produced in a melting process the ZsBeads are almost free of bubbles and pores. These properties increase their wear-resistance and prevent breaking. They are available in different fractions ranging from 0.6 mm to 1.8 mm.
