Zirconia beads, Zirconium Silicate Beads, Dispersion / Milling Media, Ceramic Shot Peening / Blasting Media.| CHEMCO 
YTZP beads are made of high-grade and nanometre yttria stabilized zirconia which is proudly produced by our own facility in large and homogenous batches. This advanced precursor material guarantees excellent mechanical properties, outstanding wear resistance and good corrosion resistance. This high density bead is used to achieve maximum milling results at minimum product contamination rates.
  • High density media ideal for high energy mills, maximizing the productivity
  • Excellent wear resistance minimizes the beads contamination during high speed milling
  • 15% superior to Ceria Stabilized beads in wear rate, proved by many tests
Medium DensitySZS
( 4.0 g/cm3 )Zirconium Silicate Beads, Sintered
SZS beads are manufactured from world-class premium zircon (ZrSiO4) mineral in a special high temperature sintering process. Because of its outstanding breakage resistance and the advantageous price, this medium density bead is particularly suitable for use in large-volume agitated bead mills.
  • Fully dense, perfect sphericity and extremely smooth beads surface
  • No porous and irregular shape problems
  • Outstanding breakage resistance
  • Optimum performance-price ratio
  • This is the bead recommended to efficiently fine-grind zircon
ZTA beads are unique products, developed by CHEMCO expert R&D team after many years of research and trials. The special formulation combines the good properties of two advanced ceramic materials (ZrO2 & Al2O3), bringing beads excellent toughness as well as outstanding wear resistance. Proven by many industrial tests, ZTA is 2 – 10 times better in wear resistance than various high alumina and high chrome steel media in the market. Its smooth bead surface offers extremely low wear to the mill internal components. And the similar density enables this bead to substitute alumina media very well.

  • Proven to be the best grinding media in terms of performance-price ratio used in Horizontal & Vertical mills for fine-grinding metallic ores concentrate & tailings
  • Superior performance-price ratio to similar density media like high alumina (92% Al2O3) Beads
  • 2 - 10 times better in wear resistance than high alumina and high chrome steel media
  • Available in big size balls up to Φ70 mm, ideal for various ball mills
  • This is the bead also recommended to fine-grind zircon
Light DensityZAL - 32 / 27
( 3.2 g/cm3 - 2.7 g/cm3 )Zirconia Alumina Composite Beads, Sintered
ZAL-32 / ZAL-27 beads are unique products, developed by CHEMCO expert R&D team after many years of research and hard work. The patented formulations combine 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 milling efficiency. And the smooth bead surface offers extremely low wear to the mill internal components. Thus these beads can substitute glass beads very well.
  • Unique formula, patented
  • Superior performance-price ratio to other low-medium density media like glass and alumina beads
  • Substitutes glass beads by increasing milling efficiency and reducing mill wear
