Zirconia toughned Alumina beads and balls: ZTA - W

Product type :- ZTA-W (Invented for Wet Grinding)

Features

  • A unique product in the market, developed by CHEMCO expert R&D team after several years of research and experiments;
  • Standard Size from 2.0-70 mm;
  • Proved by comparison wear rate tests, ZTA-W is 4 -30 times better in wear resistance than various quality High Alumina ( 90 – 92 % Al2O3 )grinding medias in globalmarket;
  • The similar density enables this product to substitute High Alumina media very well
  • Superior performance-price ratio saving users’ cost

Main applications

ZTA-Wbeads/balls are specifically suitable forwet grindingof following materials in ceramic and mining industry, just name a few:

  • Ceramic body, glaze and zircon
  • Gold, silver, platinum, lead, copper and zinc sulfide
