Product Introduction
Zriconium-aluminium composite beads are made of zirconia and alumina powder.Compared with ordinary alumina balls, Zirconia Toughened Alumina Ball have better wear resistance and more slippery surface. Generally, zirconium-aluminium composite beads are used for fine grinding of materials.
Advantages
1.Zirconium-aluminium Composite Beads has characteristic of low abrasion,corrosion resistance,impact resistance,no pollution.
2. Compared with alumina microbeads, the structure of composite zirconia beads is a composite crystal phase of zirconia and alumina, which is more delicate and dense than pure alumina microcrystals, so the wear is low;
3. At the same time, the smooth spherical surface effectively reduces power consumption and wear on equipment contacts.
Application
Zirconium-aluminium composite beads are used as grinding medium of the ball mill, stripping machine, polishing machine, sand mill etc.
