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.
Zirmil® Y
Zirmil® Y is the Premier Grade Zirconia media, which enables to obtain optimized ceramic properties for the best milling performance in all mill types. Their main characteristics are :
- High ceramic density for high energy milling
- Well controlled homogeneous grain size for high wear resistance
- Narrow bead size distribution for a better control of the final grind
