Microcrystal Alumina BeadsDURA-36
Description：
DURA-36 microcrystal alumina bead is made from high purity alumina powder with sintering method. The micro size of polycrystals contributes to wear resistance and idea strength. It is a wise choice to replace the carbon steel beads to grind the metallic and non-metallic mineral.
Applications：
—Coatings industry: marine and containers coatings, pipe coatings, armor plate coating;
—Metal minerals: copper, lead/zinc and silver minerals;
Specialty：
—Economic cost is possible to charge huge quantity of beads;
—High hardness is suitable to grinding abrasive material;
—Matching mills: big capacity bead mills.
