Abstract

Article briefly describes the application of CFD simulation technique and experimental validation in the development, improvement and optimization of flotation machine, meanwhile the paper designs an injector used for compound flotation machine according to working principle. The conical injector with shrinking angle ?=13° and the straight conical injector with shrinking angle ?=13° and length-diameter ratio l/d=3 are simulated by fluid dynamics software fluent. The paper analyzes emphatically the suction property of the two kinds of injector under the condition of different distance from the suction pipe to outlet. The results show that the suction property of the straight conical injector is superior to the conical injector. The suction property is the best for straight cone injector when distance between suction pipe and outlet within 14~22 mm.
