The abrasive ball is a kind of industrial wear-resisting material, which is often used to grind materials in industrial enterprises.
Product introduction
Alumina grinding ball is made of high-temperature alumina powder through tunnel kiln firing, with a white spherical appearance and a diameter ranging from 0.5mm to 90mm.
Feature
Alumina ball has the characteristics of suitable hardness, moderate density, wear resistance, corrosion resistance, low price, is an important engineering ceramics, is a high-tech product.Alumina porcelain ball is widely used in building sanitary ceramics, electronic materials, metallurgy, minerals, glass, cement, chemical, paint, paint and other industries, so its market is huge.In order to further reduce the cost of alumina porcelain ball and improve its wear resistance, the morphology, particle size, sintering aid, molding and sintering of the raw material were studied in detail.The wear-resistant porcelain ball is developed by utilizing the rich mineral resources of bauxite in China to meet the needs of many small and medium-sized enterprises.
Application
Mainly used in the requirements of "zero pollution" and high viscosity, high hardness of ultrafine grinding and dispersion of materials, such as: electronic ceramics, magnetic materials, zirconia, silica, zirconium silicate, titanium dioxide, pharmaceutical food, pigments, dyes, inks, special chemical industry.
