ZAL-32 / ZAL-27 Zirconia Alumina Composite beads are unique products, developed by CHEMCO expert R&D team after many years of research tests. The patented formulation combines the good properties of two advanced ceramic materials (ZrO2 & Al2O3), bringing beads excellent toughness as well as outstanding breakage resistance. Higher density of the media compared with glass could increase the grinding efficiency. And the smooth bead surface offers extremely low wear to the mill internal components. Thus these beads can substitute glass and other low-medium density grinding medias very well.

​

Until now, CHEMCO® ZAL 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, EMI mills, just name of a few...
