Description

Technical Field

[0002] High temperature alumina powder is an important raw material for the production of wear-resistant balls. Its excellent wear resistance and high hardness make it play an important role in the manufacture of wear-resistant balls. During the production process, alumina powder is made into wear-resistant balls through mixing, molding and high-temperature sintering. These balls are widely used in mining, metallurgy, chemical industry and other fields to improve production efficiency and equipment life.
