Application of 90% Microcrystal Alumina Beads
90% Microcrystal Alumina Beads are main applied in chemical,oil,cosmetic etc.industries as grinding media. The heads for these industries should have very good wear resistance and high strength to ensure the high purity of the raw materials.
Characters of 90% Microcrystal Alumina Beads
- Low wear rate with high quality of Australian raw Alumina powder of less than 1.5μm of Ultimate crystal size.
- Best appearance and varied sizes at will by advanced machine rolling processing
- Continual steady quality by automatic equipments to control the quantity of the powder and water.
- Fine crystal size to be controlled in longtunnel kiln with broad firing section.
- Valuable test results for the customers through different test methods according to customer’s equipments and use conditions.
