Abstract:The cone valve industrial pump can drive high concentration full tailings paste material into the underground through hydraulic system to complete filling operation, which has the advantages of strong pumping pressure and long transmission distance. The application and maintenance precautions of cone valve industrial pump in full tailings paste filling are introduced, which improves the efficiency of paste filling operation, promotes the development of the mine, and provides powerful technical support for the third phase construction of Wushan Copper Mine.
