Product introduction:
Alumina ceramic is widely used in industry. Using alumina powder as raw material, Titan produces all kinds alumina grinding balls, alumina grinding cylinders, alumina composite plates, alumina liners, etc.
Alumina grinding balls are excellent grinding media, which are divided into dry grinding balls and wet grinding balls. Alumina liner has strong wear resistance which can prolong the life of the equipment.
Properties:
high hardness
wear resistance
corrosion resistance
