Advantages and future development of alumina grinding balls

Alumina grinding balls are also called high alumina balls, alumina wear-resistant balls, and inert alumina balls. It is used to grind powder or granular material after the unique wear resistance of calcined alumina. It is widely used in industrial industry and powder industry.

Alumina grinding balls are widely used in ceramic factories, refractory material manufacturers, etc. At present, data shows that they have gradually replaced the grinding balls with soft stone as the medium. Using pebbles (natural balls) + 10% alumina grinding balls (φ35mm) to grind thin mud, compared to only using pebbles, can shorten the grinding time by 15%; using high alumina balls + 30% alumina grinding balls (φ35mm) to grind thin mud, Compared with the use of aluminum balls, the grinding time can be shortened by about 30%. Based on the saved electricity cost, the cost of using alumina grinding balls can be “saving” in about 2 years. A report from individual manufacturers shows that all alumina grinding balls are used to replace the original natural balls, and the output is about three times the original.

At present, most cement plants also have steel balls that were originally used, and replaced them with high alumina balls with a longer service life. Therefore, the use of alumina grinding balls to grind raw materials can not only save electricity costs and increase production, but also improve the efficiency of machinery use, which has a great protective effect on machinery and equipment.
