This is a high-quality alumina grinding balls product that's lighter than steel balls, and at the same time, much harder than them (Rockwell hardness for normal alumina balls is as high as 78). Alumina balls is a small, non-maqnetic electrical insulator that easily overcomes heat (up to 1000°C), acid, alkali, corrosion, abrasion, rust, and unlubricated rollsIn addition, alumina balls keep the ball mills from harm by elevating their utilizable volume, which extends their lifespan considerably.

Alumina grinding balls are widely used in the grinding and processing of raw materials in industries such as white cement, minerals, ceramics, electronic materials, magnetics materials, and coatings and paints. Alumina ball is a high-quality grinding medium. In the building ceramic industry, the wear efficiency of alumina ceramic grinding balls is higher than that of natural flint and pebbles.
