The invention discloses a screening and magnetic separation system for waste steel and steel slag. The screening and magnetic separation system comprises a mixed material hopper, wherein an efficient vibrating grizzly is arranged above an opening in the upper part of the mixed material hopper; a variable frequency electric vibrating feeder and a belt conveyor are arranged below a material leaking opening in the lower part of the mixed material hopper; the belt conveyor is obliquely arranged; the lower end of the belt conveyor is positioned below the variable frequency electric vibrating feeder and the higher end of the belt conveyor uses an adjustable magnetic core type permanent magnetic roller; a shunt is arranged below the adjustable magnetic core type permanent magnetic roller; the shunt is two funnels, one of which is a fine powder and iron block funnel and the other one of which is a nonmetal funnel; and an electric vibrating screen is arranged below the fine powder and iron block funnel. The invention further discloses a screening and magnetic separation method of the system. Through the adoption of the technical scheme, the traditional steel (iron) slag magnetic separation process and equipment are greatly simplified; the mounting cost is reduced; a very quick effect is achieved; and purposes of increasing production efficiency, reducing labor intensity of a worker and reducing production cost are achieved.
Description
Technical field [0001] The invention belongs to the technical field of metallurgical industrial production, and relates to the processing technology of scrap steel and steel slag. More specifically, the invention relates to a sieve magnetic separation system for scrap steel and steel slag. In addition, the present invention also relates to the sieve magnetic separation method of the system. Background technique [0002] Steel-making, cast pipe and other metallurgical production units produce scrap steel (iron), steel slag and other mixtures with an iron content of more than 40% during the production process, and the mixtures have different shapes and sizes. use. [0003] However, in the prior art, the slag processing capacity of the steelmaking department is limited, and this part of the mixture cannot be magnetically separated, resulting in a large amount of waste metal waste. Summary of the invention [0004] The invention provides a sieve magnetic separation system for scrap st...
