High Density Beads
Zirconia Beads, Partially Stabilized with Yttria, Sintered
YTZP yttria zirconia beads are made of high-grade and nanometre Yttria Stabilized Zirconia (YSZ) 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 throughput and productivity
High fracture toughness and high wear resistance minimize the contamination of beads during high speed milling
At least 15% superior to Ceria Stabilized Zirconia medias in wear rate through many tests
Always excuting higher quality control standard in the industry, our products' quality can get effective assurance .
Medium Density Beads
Zirconium Silicate Beads, Sintered
SZS Zirconium Silicate 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.
A medium density media 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
Medium Density Beads & Balls
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.
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

Zirconia Alumina Composite Beads, Sintered
ZAL-32 / ZAL-27 Zirconia Alumina Composite beads are unique products, developed by CHEMCO expert R&D team after many years of research tests. The patented formulation combines 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 grinding efficiency. And the smooth bead surface offers extremely low wear to the mill internal components. Thus these beads can substitute glass and other low-medium density grinding medias very well.
Light density medias with unique formulations, patented
Superior price-performance ratio to other low-medium density grinding medias
Substitutes glass beads very well by reducing media & mill wear and increasing grinding efficiency
CHEMCO is a world class ceramic beads and balls producer. All our products' formulations contain more or less Zirconia (ZrO2), which is an advanced ceramic material with a title of "Ceramic Steel". This single material offers the traditional ceramics benefits of hardness, wear and corrosion resistance. We can supply various densities (Light, Medium & High) media with the complete range of sizes (∅0.01 - 70 mm), which suit different fine-grinding (milling & dispersion) as well as impact surface treatment applications. We've been proudly exporting our products from China to more than 45 different countries around the world!
CHEMCO has a dedicated R&D department manned by committed scientists and technicians. As a team they constantly strive to explore and innovate the new value of products. The company has also established a complete quality control system and maintained an individual department controlling the products' quality. Equipped with a complete set of modern analysis instruments and always executing higher standard in the industry, our products quality can get effective assurance.
