Scrap steel crushing and recycling device

Abstract

The utility model belongs to the technical field of waste steel crushing and recycling, and particularly relates to a waste steel crushing and recycling device which comprises a crusher, a speed reducing motor and crushing rollers, the crushing rollers are rotationally arranged in an inner cavity of the crusher and are symmetrically arranged, a discharging conveying belt is arranged below the crusher, a feeding conveying belt is arranged above the crusher, and a discharging conveying belt is arranged below the feeding conveying belt. A strong electromagnet is arranged at the bottom of an inner cavity of the feeding conveying belt, and a fixing frame is arranged below the feeding conveying belt. The lifting top plate can lift up waste steel, after the waste steel is close to the lower portion of the feeding conveying belt, the strong electromagnet can adsorb the steel, the waste steel is adsorbed to the lower surface of the feeding conveying belt, the feeding conveying belt drives the waste steel to move on the lower surface and move to a crusher, and after the waste steel reaches the end of the feeding conveying belt, the waste steel is conveyed to the crusher. And after the adsorption force of the strong electromagnet to the scrap steel is reduced, the scrap steel can fall into the crusher, so that automatic feeding of the scrap steel is realized, and the safety during crushing treatment of the scrap steel can be improved.
