1. Introduction
Zirconium grinding media has high density and toughness and super hardness, so it has better grinding efficiencies compared with other grinding media such as Alumina and Agate. The high wear-resistant zirconium grinding media prevents materials from being contaminated and chemical etching or short service life of the grinder.
These special feature make zirconium grinding media especially suitable for material grinding in important occasion.
