Alumina grinding ball refers to aluminum oxide powder as raw material, after batching, grinding, powder (pulping, mud), molding, drying, burning and other processes made into, mainly as grinding medium and widely used ball stone. Because the content of alumina is more than 92%, it is also called high aluminum ball. Appearance is white ball, diameter from 0.5-120mm.

Alumina grinding ball use: With high strength, high hardness, high wear resistance, large ratio, small volume, high temperature resistance, corrosion resistance, no pollution and other excellent characteristics are widely used in different types of ceramics, porcelain glaze, glass, chemical factory thick hard material finishing and deep processing, is the ball mill, pot mill, vibration mill and other fine grinding equipment grinding medium, Its grinding efficiency and wear resistance is much better than ordinary pebble or natural pebble.

Alumina grinding ball characteristics:

(1) The main component of the product is high quality alumina, high whiteness, has no effect on the quality of the ground material.
(2) The product adopts rolling and isostatic pressing molding, which can greatly improve the grinding efficiency, reduce the grinding time, and effectively increase the effective volume of the ball mill, thus increasing the amount of grinding materials.
(3) The product has low wear and can greatly prolong the service life of the grinding body.
(4) The product can withstand more than one thousand degrees of high temperature, acid, alkali and corrosion resistance
