Problems solved by technology

Ceramic wear-resistant balls in the prior art are generally made of two raw materials, alumina powder and bauxite. Ultrafine powder is prepared by wet ball milling and spray granulation, and then formed by cold isostatic pressing under a pressure of 35-40 MPa. , and finally through high-temperature firing to prepare alumina grinding balls. The aluminum content of alumina products reaches more than 90%, and the products are at a higher level. However, this process has disadvantages such as high cost, high firing temperature, and high energy consumption; The content is low, generally around 70%. It is a low-grade wear-resistant medium. It is generally used for the grinding of ceramic blanks. The cost is low, but it has the disadvantages of yellow color, low specific gravity, large wear, and cannot be used for the grinding of glazes.
