CENOTECCenotec CZY

In particle grinding, the performance of the grinding machine is of primary importance, but the quality (high density, high hardness, high wear-resistance, high strength, and size distribution) of the grinding medium, which is charged into a grinding machine to play the role of providing the actual motion, is very important as well. The initial investment cost for CENOBEAD™ CZY is relatively high compared with CZC and CZS, but it leads to high productivity and low maintenance/repair costs, and furthermore, lengthens the lifetime of the grinding machine, making it the optimum grinding medium.

CENOBEAD CZY is a grinding medium of the highest quality that meets with customers`needs. Its features are:

Features and Application

  • CENOBEAD™ CZY has high density and hardness, making it suitable for high-quality products, such as automobile paints and inks.
  • It is suitable for high-efficiency horizontal mills and basket mills.
  • It has high wear-resistance and no contamination, so it is suitable for electronic ceramics, foods, cosmetics, and pharmaceutical products that require zero contamination from the grinding medium.
  • It has high compression strength and a narrow size, making it suitable for the production of fine particles.
  • With possible sizes of 0.3mm and lower, it is suitable for industries requiring nano-sized particles.
