Alumina Grinding Ball

- Jun 15, 2017 -

Alumina ball refers to bauxite, roller powder, alumina, high temperature calcination Alfa alumina powder as raw material, after mixing, grinding, milling (pulp, clay), molding, drying and sintering processes produced, mainly as a grinding medium is widely used ballstone. According to the different alumina content, can be divided into the middle aluminum ball, the middle high aluminum ball and the high aluminum ball.

In general, we divided the content of 60% - 65% alumina into "aluminium ball", and the content of 75% - 80% alumina was called "medium high alumina ball". More than 90% of alumina content was high alumina ball. Among them, the high aluminum ball is subdivided into 90 porcelain, 92 porcelain, 95 porcelain and 99 porcelain. 99 porcelain because of its high production costs and few large manufacturers, large quantities of manufacturing, is now mainly for some special ceramics factory by hand.

The aluminium ball and medium aluminium ball are accepted by most ceramic factories because of their lower price. They are mainly used for grinding ceramic billets. High aluminium ball because of high strength, high hardness, high wear resistance, heavy, small volume, high temperature resistance, corrosion resistance, no pollution and other excellent properties have been widely used in different types of ceramic, enamel, glass, chemicals and other factories thick hard materials and deep processing, especially in the 92 content alumina balls were most commonly used.
