Yttria Stabilized Zirconia Beads

Zirpro offers a comprehensive range of high density Yttria stabilized Zirconia beads, Zirmil® Y, engineered to the highest specifications of advanced ceramic materials and technology. Zirmil® Y beads are  precision products with class-leading physical characteristics and performance. They are used in all mill types and are particularly suited to high energy and re-circulation processes.

Yttria-Stabilized Zirconia

Zirmil Y milling media are all based upon a unique in-house technology using ZirPro’s own advanced yttria-stabilized zirconia powder as the only raw material. This enables precise control of grain size, a critical factor in optimizing bead wear behavior.

Beads size distribution and shape

All Zirmil Y beads are offered with a narrow bead size distribution and perfect spherical shape, which provides superior operational performance. Although bead lifetime is dependent on suspension formulations, Zirmil Y is commonly used for extremely long periods of time.
