high alumina ball

Jan 09,2016
The high alumina ball is a category of the alumina ball, because of its high alumina content and is referred to as high alumina ball. The high alumina ball can be subdivided into 90, 92, 95, 99 and so on. High alumina ball because of its high strength, high hardness, high wear resistance, large proportion, small volume, high temperature resistance, corrosion resistance, no pollution and other excellent properties, is widely use in the deep processing of thick and hard materials like different types of ceramic, enamel, glass, chemicals and other factories. To 92% content of high aluminum ball for example, its specific gravity (density) should reach more than 3.60, the alumina content reached more than 91.5%, with iron low. Same raw materials, the same formula, the same burning temperature, raw material after grinding fineness smaller, the higher the proportion, the better the wear resistance. High alumina ball is the main proportion pollinated material and firing effect, burned (burn unfamiliar), powder is too coarse, plus the complex material and other factors will result in insufficient proportion of coccolith. Low proportion of coccolith not wear-resisting, easy to crack, but high proportion can not on behalf of the coccolith certain wear, because excessive sintering ballstone can also reach a higher proportion. Coccolith most important quality is reflected in the wear resistance and some testing agencies can also do the wear test, but data for reference only, because laboratory detection of environmental conditions and production environment is very different, is first detected mill, and many manufacturers are dry grinding; detection. Secondly, a lot of times is not into other materials, just coccolithophores and coccolith between friction, while the actual production process is to add a variety of raw materials of. With high aluminum ball grinding material, not only can save electricity, improve production, but also improve the efficiency of the use of machinery, mechanical equipment has a great role in the protection.
