High alumina ball

High alumina ball is a type of alumina ball, because of its high content of alumina is referred to as high alumina ball. High alumina ball according to the alumina content can be subdivided into 90, 92, 95, 99 series. High alumina ball because of its high strength, high hardness, high wear resistance, than the major, small volume, high temperature resistance, corrosion resistance, no pollution and other excellent properties, is widely used in different types of ceramic, enamel, glass, chemical factories and so on thick hard material finishing and deep processing.

The 92% content alumina balls as an example, its specific gravity (density) should reach more than 3.60, alumina content reached more than 91.5%, lower iron. The same raw materials, the same formula, the same sintering temperature, the powder fineness is smaller, the higher the proportion is, the better the wear resistance. The proportion of major pollinated by high aluminum ball material and the influence of burning, burning of Health (the burning of the unfamiliar), powder is too thick, add a complex material and other factors will cause the coccolith proportion is not enough. The proportion of low stone not wear-resisting, easy to crack, but the proportion of high cannot represent stone must wear, because of excessive sintering ball can also reach a higher proportion.
