80% Zirconia Grinding Beads – Polishing and Grinding Media
80% Zirconia Grinding Beads are widely used as polishing media for wet ultrafine grinding of non-metallic minerals such as alumina, ultrafine zirconium silicate, silica powder, and titanium dioxide, as well as metallic minerals such as copper, silver, nickel, gold, and zinc. They are suitable for slow-speed stirring mills.
Product Features:
1. Optimized product formula, advanced processing equipment, uniform internal crystalline phase, and fine microcrystalline structure.
2. Solid and robust, with good roundness, no empty beads, reasonable particle size distribution, low wear, and reduced operating costs.
3. Smooth surface, gentle on sand mills, and minimizes wear on the mill.
