Alumina ball
1. Detailed description
With high strength and hardness, excellent wear resistance and corrosion resistance, the products are widely used in ceramic tile, sanitary ware, industrial ceramic, electronic ceramic, advanced refractory, special cement and enamel, non-metallic powder processing, chemical engineering, medicine and paint industries.
2. Characteristics:
A. High density and hardness, improving markedly grinding efficiency and saving electricity by 30-40%.
B. Excellent wear resistance which insures high purity of the milled powders.
C. Reducing the thickness of ball mill, increasing usable cubage and improving mill capacity.

5. Usage:
(1) It has very excellent thermal properties, with its high density high-temperature resistance 1550, also it's a good choice for heat retention or equilibration media.
(2) For its superior chemical resistance, it's suitable for applications in olefin processes, such as ethylene dryers.
(3) Also alumina products for grinding such as alumina ball, ring and cylinder.
