High alumina ceramic ball

High alumina ball is a kind of alumina ball, which is called high alumina ball because of its high alumina content

High alumina ball is made of bauxite, roller powder, industrial alumina oxide powder, high-temperature calcined alpha alumina oxide powder and other materials as tableland materials, through batching, grinding, pulverizing, forming, drying, firing and other processes. It is widely used as a grinding medium.

According to the alumina content, high alumina ball can be subdivided into 90, 92, 95, 99 series. Taking 92% content of high alumina ball as an example, its specific gravity should be more than 3.60, alumina content should be more than 91.5%, and iron content should be low.

Under the same raw materials, the same formula and the same firing temperature, the smaller the fineness of the powder after grinding, the higher the specific gravity and the better the wear resistance.

Characteristics of high alumina ball

High alumina ball has the characteristics of high purity, high strength, high hardness, high whiteness and low wear, which has no effect on the quality of grinding materials.

The high alumina ball has the characteristics of a large ratio, which can greatly improve the grinding efficiency and reduce the grinding time.

The high alumina ball has the characteristics of low wear, which can greatly extend the service life of the grinding body.

High alumina ball has the characteristics of high-temperature resistance, acid and alkali resistance and corrosion resistance.

The high alumina ball solves the problem that the grinding medium pollutes the raw material

Application of high alumina ball

1. The high alumina ball is mainly used for finishing and deep processing of thick and hard materials in different types of ceramics, enamels, glass and chemical plants. It is the grinding medium of ball mill, pot mill, vibration mill and other fine grinding equipment. Its grinding efficiency and wear resistance are much better than ordinary pebbles or natural pebbles.

2. Grinding and dispersion of non-metallic mineral powder (such as zirconium silicate, kaolin, etc.) and materials in the coating, paint and other industries, as well as polishing of metal parts, suitable for all types of grinding and polishing equipment.

3. The high alumina ball is filled in the rubber when pouring to increase the wear resistance coefficient.

4. As the high alumina ball has the characteristics of high -temperature resistance, it can be used as the ball under the pusher kiln
