Screening and magnetic selection system of waste steel and steel dreg

The utility model discloses a screening and magnetic selection system of waste steel and steel dreg, comprising a mixture hopper, wherein an efficient vibration grid sieve is arranged above an opening of the upper part of the mixture hopper; a variable-frequency electric vibration feeder and a belt type conveyor are arranged below a material leaking opening at the lower part; the belt type conveyor is obliquely arranged; the lower end of the belt type conveyor is located below the variable-frequency electric vibration feeder and the higher end of the belt type conveyor is provided with an adjustable magnetic core type permanent-magnetic rotary drum; a flow divider is arranged below the adjustable magnetic core type permanent-magnetic rotary drum; the flow divider is formed by two funnels; one funnel is a fine powder and iron block funnel and the other funnel is a non-metal funnel; and an electric vibration sieving net is arranged below the fine powder and iron block funnel. With the adoption of the technical scheme, traditional steel (iron) dreg magnetic selection process and equipment are greatly simplified and the installation cost is reduced; and the effect is quick and the aims of improving the production efficiency, reducing the labor strength of workers and reducing the production cost are achieved.
