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:
