Product Description

90-99% Alumina Ceramic Grinding Balls for Industrial Milling and Grinding Equipment

Grinding Balls are suitable for grinding medium used in ball grinding machines.The products are featured by high hardness, big density, low wear lost, good normalizations, good corrosion-resistance etc. They are the most ideal high-efficient grinding media for milling glaze materials, and various powdered ore. They are using ceramics, cements, paints, refractory, inorganic mineral powders and other materials to form. And the detailed information please refer to following:
 

1. High wear-resisting: The alumina balls wear resisting is higher than the common ceramic balls. When it is working, the ball will not pollute the grinded materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.

 

2. High density: the high density, high hardness and the high grinding Characters save the grinding time, enlarge the smashing room. So It can improve the grinding efficiency.
