Our unique ZTA beads & balls enjoy 50%+ less wear than any Alumina grinding media in the market saving your grinding costs !

Zirconia Toughened Alumina Beads & Balls, ZTA

Medium Density Beads & Balls

Type: ZTA

(3.65 g/cc)

Zirconia Toughened Alumina Beads and Balls, Sintered

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.

Features

  • Available in big sizes balls up to 70 mm, especially suitable for ball mills

  • At least 2 times better in wear resistance than “the best” high alumina ( 90 - 92 % Al2O3 ) media in the world market, proved by many tests

  • Superior performance-price ratio saving users’ cost

  • Higher impact strength makes the media not only suitable for wet grinding but also ideal for dry grinding

  • This is the bead also recommended for fine-grinding zircon

Main Applications

ZTA beads can be used in milling and dispersion of following materials, just name a few:

  • Ceramic body, glaze and zircon

  • Gold, silver, platinum, lead, copper and zinc sulfide

  • Coatings (wet ball milling)

  • Cement
