Zirconia Toughened Alumina (ZTA) BallsDURA-39

lDescription

DURA-39 Zirconia Toughened Alumina (ZTA) ball was formed from the ultra fine alumina powder that toughened by nano zirconium silicate. It combines the benefits of the high hardness of alumina and the  excellent toughness of the zirconium silicate, which deliver outstdanding cost performance to disperseand grind the hard and brasive ores.

lApplications

Metallic minerals industry: copper concentrate, lead/zinc, silver, and platinum tailing.

Non-metallic minerals: ZrSiO4, Kaolin, CaCO3 and SiO2.

lSpecialty

Low sliding friction coefficient results in high energy efficiency;

Consistent microstructure benefit low bead consumption;

High sphericity and roundness to improve the fluidity;

—Matching mills: big volume stirred mill with discs or pins.
