Alumina grinding balls mean in bauxite, roller powder, industrial alumina powder, high temperature calcined material such as alpha alumina powder as raw materials, ingredients, grinding milling, pulp, mud, molding, drying and firing process is made and be become, such as main is widely used as grinding media ball stone.
【The classification of the alumina grinding balls】 :
Alumina grinding balls according to different alumina content can be divided into: aluminum ball, high aluminum and alumina ball. We usually put 60% 65% alumina content is divided into aluminum ball; 75% 80% alumina content are called high aluminum ball, more than 90% of the alumina content for high alumina ball. With high alumina ball and subdivided into 90 porcelain, 92 porcelain, 95 porcelain, 99 porcelain, porcelain and 99 because of its high production cost and the mass production, there are very few large manufacturers at present mainly for the part of special ceramics factory by hand.
【Application alumina grinding balls】:
Chinalco and high aluminum ball because of its low price and is accepted by most of the ceramics factory, mainly used for grinding ceramic blank. High alumina ball since it has high strength, high hardness, high wear resistance, than the big, small volume, high temperature resistant, corrosion resistance, no pollution and other excellent properties, and is widely applied to different types of ceramic, enamel, glass, chemical
