Alumina micro beads
Application
• High performance abrasion resistance alumina micro bead is mainly used for non-metal mineral products extra refining, it is the ideal grinding media for stirring grinding, sand grinding and vibration grinding. It is widely applied in ceramics,paint, ink, coatings, dyes,rubber and power industries.
Performance:
• High density and hardness, impact resistance, low wear rate, smooth surface and no contamination to product.
• Fine chemical stability, anti-corrosion, no pollution to the grinded products.
• Under condition of appropriate ball size ratio, it can achieve high grinding efficiency with material results D50≤1µm
• High performance and low price
