Zirconia Toughened Alumina Beads and Balls, Sintered (Invented for Wet Grinding)
ZTA-W beads & balls are unique products, developed by expert R&D team after several years of research and experiments. We adopt our experienced roll / granulation method for forming this type of products to make it specifically suitable for wet grinding applications. Proved by many comparison wear rate tests, ZTA-W shows 4 - 30 times better in wear resistance than various quality High Alumina ( 90 - 92 % Al2O3 ) grinding media in global market, and its similar density enables this product to substitute High Alumina media very well.
Until now, 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.
Features
Available in big sizes balls up to ∅70 mm, which suits wet-grinding in ball mills
At least 4 times better in wear resistance than “the best” High Alumina ( 90 - 92 % Al2O3 ) grinding media in the world market, proved by many tests
The product's similar density enables it to substitute High Alumina media very well
Superior performance-price ratio saving users' cost
This is the grinding media recommended by us for fine and ultra-fine grinding gold, silver, platinum, lead, copper and zinc sulfide
