The blanks and glazes used in the building and sanitary ceramics industry with wall and floor tiles as the leading products are ground with a ball mill. Most companies still use natural ball stone as the grinding medium. Natural ball stone has poor wear resistance. Ceramic grinding balls inevitably contaminate the glaze during the grinding process. At the same time, due to the low density of natural ball stone, the grinding efficiency is low. It is one of the pursuits of ceramic enterprises to seek and use cheap and fine grinding media. Since the 1950s, aluminum oxide ceramic grinding balls have entered the field of ceramic production. In 1998, the total output of building ceramics in China was 1.594*10m, and the total output of sanitary ceramics was 51.45 million pieces, accounting for 1/3 and 1/5 of the world’s output, respectively. It is considered to be the world’s largest producer of building sanitary ceramics. Hope to maintain the status of the world's largest producer of building sanitary ceramics.
According to the ideal product structure, the high-end products are estimated at 20%. The loading of alumina ceramic grinding balls required in the country is about 40000t, and the comprehensive demand for high-grade ceramic grinding balls should be about 50000t/a. As natural cobblestones are on the verge of exhaustion, ideal cobblestones are difficult to buy. High-quality cobblestones seriously affect the quality of grinding materials and the grade of products, forcing companies to choose alumina ceramic grinding balls with excellent characteristics . The use of alumina ceramic grinding balls as grinding media to improve the quality of products has been the consensus of the ceramic industry. Therefore, the market demand for alumina ceramic grinding balls in the ceramic industry is great.
