Yttrium Stabilized Zirconia Grinding Beads

YTZ® Grinding Media Features

YTZ® Grinding media is a high density, highly spherical product that is the ultimate in high performance dispersion media for horizontal mills.   It's density (> 6 g/cc) makes it ideal for high viscosity mill bases. 

The shiny, nearly defect-free surface of YTZ® beads is extremely smooth, for very low mill and media wear.   Look at the photo to the left.  The grinding beads are shiny initially, and the surface becomes even smoother after the first use.

YTZ® beads are not inexpensive.  This begs the question, "How can I benefit from the performance characteristics of this product, i.e. what is the cost/benefit ratio?"  With the quality demanded by high performance coatings users, combined with the very long lifespan of the grinding beads, the advantages of YTZ® beads become apparent.  Consistent grinds, very high production rates, and the availability of very small diameter sizes make YTZ® beads cost effective for many applications.

Another advantage of YTZ® beads is that they do not oxidize ("rust") in the presence of aqueous dispersions.  As a result, they offer the advantages of the density of metallic media without the oxidation.
