Zirconia Grinding Media

Magnesia Stabilized Zirconia grinding media mills twice as fast as equivalently-sized alumina media with only 1/2 the media weight loss and only 1/3 the wear (weight loss) of the grinding jar, with accompanying reduced batch contamination. Available in radius end cylinders, with length equal to their outside diameters.

Features: 

  • 1.6 times denser than high alumina

  • Hard, non-porous surface, chip resistant, easily cleaned.

  • Non-conductive, non-magnetic, excellent resistance to mechanical and thermal shock

  • Spheres and beads also available

Specifications:

1/4" Radius end cylinder.................. 485 PCs/lb
3/8" Radius end cylinder.................. 150 PCs/lb
1/2" Radius end cylinder.................... 65 PCs/lb
3/4" Radius end cylinder ....................50 pcs/lb
(Piece count is approximate)

NOTE: With a specific gravity of 3.42, the charging factor of Burundum (pounds of media to be used per gallon of total jar capacity to give a 50% vol. Media charge) is approximately 9 lbs/gallon.
