Zirmil® Y

Zirmil Y ceramic grinding beads

The Premier Grade Zirconia Media

Zirmil® Y is engineered to the highest specifications of advanced ceramic materials and technology. It is a precision product with class-leading physical characteristics and performance. Zirmil Y is used in all mill types and is particularly suited to high energy and re-circulation processes.

Yttria-stabilized zirconia

Zirmil Y milling media is 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.

Long lifetime

Zirmil Y is 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 — often for more than 10,000 hours. Zirmil Y helps to ensure long, non-disruptive production runs with high productivity.
