Aluminum balls

High alumina ceramic ball is a ball of aluminum category, because of its high alumina content is referred to as High Porcelain aluminum ball. According to an alumina content of high alumina ceramic ball can be divided into 90,92,95,99 series. Alumina ball because of its high strength, high hardness, high wear resistance, heavy, small size, high temperature, corrosion, pollution and other excellent properties and is widely used in different types of ceramic, enamel, glass, chemicals etc. factory thick hard material finishing and processing. Alumina ball of user-based ceramics factory, there are data show that the use of pebbles (natural stone ball) + 10% aluminum ball (φ35MM) grinding mud, pebbles contrast only can shorten the grinding time by 15%; use aluminum ball + 30% aluminum ball (φ35MM) grinding mud, in contrast with only aluminum ball, grinding time can be shortened by about 30 percent, simply to electricity savings, roughly two years to be able to because of the use of high alumina Ball and higher costs "province" back. The report shows that there are individual manufacturers, all to replace the original natural stone ball with aluminum ball, the yield is about 3 times the original. Grinding balls with high aluminum raw materials, not only save electricity, improve yields, and improve the mechanical efficiency in the use of machinery and equipment are significant protective effect. In addition to the ceramics industry, quartz, chemical and other industries also have to try to use aluminum ball production. Which is mainly used in the production of silica powder quartz plant, proved producing 325 mesh silica powder, quartz balls for replacement with high alumina balls, can significantly improve the yield and quality of products, such as brightness, uniformity, etc., and because loss quartz ball speed is not fast, it saves the ball stone add manpower and time costs.
