ZTA beads & balls are unique products, developed by CHEMCO expert R&D team after several years of research and tests. We are adopting the roll / granulation method for forming the small sizes beads, while using Isostatic Wet Bag Press to shape the big sizes balls. Proved by many industrial tests, ZTA is 2 - 15 times better in wear resistance than various quality high alumina ( 90 - 92 % Al2O3 ) media in the market, and the similar density enables this product to substitute high alumina grinding media very well. Until now, CHEMCO® ZTA Zirconia Toughened Alumina Beads & Balls are successfully being used in many modern types of mills, which include vertical mills, horizontal mills, agitated media mills and stirred media mills, such as IsaMill™, Metso Vertimill®, Metso SMD, FLSmidth® VXPmill, OUTOTEC HIGmill® and many conventional ball mills.
