Grinding Media
 
ZIROX

Available in Three Types:

   
Grinding Media | PERLITE Glass Beads | DURMAX Steel Beads | ZIROX Zirconium Beads
 
ZIROX-70 Zirconium Silicate
 

ZIROX-70 is general purpose and lower priced fused Zirconia bead which makes for an inexpensive alternative to glass beads.

The beads do not have to be "run in" before use. Color is white. ZIROX-70 is available in either standard screened sizes or narrow screened sizes.

ZIROX-TZP Zirconium Oxide with Yttria Stabilizer (High Density Zirconium Oxide)
 

ZIROX-TZP is the highest density non-metallic Grinding Media we offer. The cost per pound is higher than ZIROXZ-70 but the life expectancy is much greater and in most cases outweighs the extra cost . This extra life will very often more than justify the extra expense especially when also considering the reduced mill downtime due to media changes.

Bead fragmentation is virtually nil thereby eliminating problems associated with clogged screens.
