SZS Zirconium Silicate Beads are manufactured from world-class premium zircon (ZrSiO4) mineral in a special high temperature sintering process. Because of its outstanding breakage resistance and the advantageous price, this medium density bead is particularly suitable for use in large-volume agitated bead mills.

​

Until now, CHEMCO® SZS Zirconium Silicate Beads are successfully being used in all modern types of mills, which include vertical mills, horizontal mills, agitated media mills, stirred media mills, such as IsaMill™, Metso Vertimill®, Metso SMD, FLSmidth® VXPmill, OUTOTEC HIGmill®, HOSOKAWA ALPINE agitated media mills, NETZSCH mills, Buhler bead mills, DYNO® mills, CMC Supermill PLUS®,  'Red Head' vertical media grinding mills,  Niemann Kreis-Basket-Mill®  Getzmann bead mill & basket mill, Vollrath bead mill, HCP Immersion mill, IEC basket mill & bead mills, just name of a few...
