Product Description
Calcium carbonate is the major application for alumina ceramic grinding balls, although they can also be used for shot peening, polishing, and other metal surface treatments. We can match various density grinding beads and balls with the customer's various grinding machinery.
Properties
1. The surface features outstanding goss and good sphericity. The product sinters compactly and is free of flaws like porosity and other issues.
2. Outstanding toughness, greater crushing strength than ordinarily occurring alumina beads, and non-fragmentation in prolonged high-speed operation.
3. Strong stability, alkali and acid resistance.
4. Low employee turnover.
Application
Alumina grinding balls use: a degree, high hardness, high wear resistance, than the big, small volume, high temperature resistant, corrosion resistance, and other features and is widely applied to different types of ceramic, enamel, glass, thick hard material finishing and deep processing of the chemical factory, is a ball mill, cylindrical grinding machine, vibration grinding machine, fine crushing equipment of grinding media, its crushing grinding efficiency and wear resistance significantly To the ordinary ball or natural stone pebbles.
