Abstract:In order to realize the energy saving and comprehensive recycling of resources in mining enterprises, this study aims at the technical transformation of non-ferrous metal flotation machine. Combined with the technical parameters of flotation machine at home and abroad, the shape and size of impeller and stator of the main shaft mixing system of flotation machine are studied and analyzed. Through CFD numerical simulation and pulp test verification, the structure of the existing flotation machine mixing system is optimized and designed, and finally CGF-Y type efficient energy-saving flotation machine is developed. The flotation machine has been tested in JinNiu Gold Mine and JiaMa Copper Mine respectively, which can reduce energy consumption and improve ore dressing recovery. At present, the 80 m3 flotation machine has been applied in Taibai Gold Mine with stable operation.
