Grinding ball material mostly are alumina and zirconia which mainly used in chemical and mechanical grinding powder, and the sample particles by grinding particle diameter is smaller.
Refers to the bauxite, roller powder, industrial alumina, high temperature calcinations Alfa alumina powder as the raw material, after mixing, grinding, milling (pulp, making mud), forming, drying, sintering processes is made, and mainly used as grinding media and widely use of ball. According to the alumina content of different, it can be divided into the aluminum ball, high aluminum ball and high alumina ball. Generally the 60% – 65% alumina content of zoned are regarded as aluminum ball, 75% – 80% of alumina content is called high aluminum ball, 90% alumina content of high alumina ball. The high aluminum ball is subdivided into 90 porcelain, 92 porcelain, and 95, 99 porcelain. Because of its high production cost, the 99 porcelain has a few large manufacturers choose to mass production, and mainly made by part of special ceramics factory by handmade. Due to the lower price of the aluminum ball and high alumina ball, and accepted by most of the ceramic factory, which mainly used for grinding ceramic blank. High alumina ball because of its high strength, high hardness, high wear resistance, thick and hard material finishing and deep processing of heavy, small volume, high temperature resistance, corrosion resistance, no pollution and other excellent properties, it is widely used in different types of ceramic, enamel, glass, chemicals and other plants, especially the 92 content alumina balls were most commonly used.
