Alumina grinding balls refers to the use of alumina powder as raw material, which is made by batching, grinding, pulverizing (pulping, mud making), molding, drying, firing and other processes. It is mainly used as a grinding medium and is widely used Of balls. Because the content of alumina is above 92%, it is also called high alumina ball. The appearance is white spherical, with a diameter ranging from 0.5-120mm. 

Properties of alumina grinding balls

Purpose of alumina grinding ball: It has high strength, high hardness, high wear resistance, high specific gravity, small volume, high temperature resistance, corrosion resistance, pollution-free and other excellent characteristics. It is widely used in different types of ceramics, enamel, glass, etc. The fine processing and deep processing of thick and hard materials in chemical plants are the grinding media of ball mills, pot mills, vibration mills and other fine grinding equipment. Its grinding efficiency and wear resistance are much better than ordinary ball stones or natural pebbles. 

Characteristics of alumina grinding balls:

(1) The main component of the product is high-quality alumina with high whiteness, which has no effect on the quality of the material being ground.
(2) The product adopts rolling and isostatic pressing molding, which has a large specificity, which can greatly improve the grinding efficiency, reduce the grinding time, and effectively increase the effective volume of the ball mill, thereby increasing the amount of grinding material added.
(3) The product has low abrasion and can greatly extend 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
