Alumina pipe for mining industries is suitable for anti-wear of various mining equipment, such as coal, copper, tungsten, nickel, iron ore, and other mines. High requirements for grinding performance.
It is used for mine filling, concentrate powder, and tailings transportation, which has serious wear on the pipeline. The service life of the ore powder transportation pipeline used in the past is less than one year, and the service life of the alumina pipe for mining industries can be increased by more than 10 times.
Mineral beneficiation is an essential process in the comprehensive utilization of mining resources. Many metals and non-metallic components in mineral processing equipment are worn out due to continuous work, resulting in a lot of loss of human, material, and financial resources and affecting production efficiency. Therefore, the beneficiation equipment is severely worn and has a short service life. It has a serious impact on the development of beneficiation production.
Alumina pipe for mining industries has become one of the most commonly used materials in the washing industry due to its superior material properties, which are characterized by high hardness, wear resistance, and corrosion resistance. The alumina ceramic tube with alumina as the main component has the advantages of simple process, low processing cost, and good wear resistance.
