Mainly ceramic plants. According to data, pebbles (natural ball stones)+10% high alumina balls are used（ φ 35MM) grinding mud, compared with only pebbles, can shorten the grinding time by 15%; Use medium aluminum ball+30% high aluminum ball（ φ 35MM). Compared with using only medium aluminum balls, it can shorten the grinding time by about 30%. Based on the saved electricity cost, it can "save" the cost of using high aluminum balls in about two years. According to the report of some manufacturers, the ball mill uses high alumina ball and high alumina lining bricks to replace the raw materials of Chinalco grinding ceramics. The ball stone loss is less than one third of Chinalco ball, the grinding time is reduced by 20%, the product quality is more stable, and the use of high alumina products is longer. The ball lining does not need to be replaced frequently, and the overall use of the ball is more cost-effective. Grinding raw materials with high aluminum balls can not only save electricity costs, increase output, but also improve the efficiency of machinery, which has a great protective effect on mechanical equipment.
In addition to the ceramic industry, quartz, chemical and other industries are also trying to use high alumina balls for production. The quartz factory is mainly used to produce silica micro powder. Practice has proved that, for example, if 325 mesh silica micro powder is produced, grinding with high alumina ball instead of quartz ball can significantly improve the output and product quality, such as whiteness, uniformity, etc., and because the loss rate is not as fast as that of quartz ball, the labor and time cost of adding pebble are saved. The main problem encountered with the use of high alumina ball is that due to its high hardness and brittleness, dry grinding is easy to cause the ball stone to crack, and the surface of the ball stone is pitted, which will lead to very high wear. The method of polishing the ball stone before leaving the factory can only be used to pick out the cracked or high wear ball stone, so as to minimize customer losses.
