Steel mill waste residue crushing magnetic-separation processing device

Abstract

The invention relates to the technical field of waste residue treatment, and particularly relates to a steel mill waste residue crushing magnetic-separation processing device. The device comprises a stock bin, a double-shaft crusher, a cross beam, a supporting plate, a first belt roller, a second belt roller, a transmission belt, a rubber pad, a magnet strip, a rectangular frame body and a brush roller, wherein the steel slag crushed by the double-shaft crusher falls onto the rubber pad with the magnet strip; the rotating transmission belt drives the rubber pad to move together, so that the rubber pad drives the crushed steel slag to move, iron waste residues in the crushed steel slag are attached to the surface of the rubber pad under the adsorption of the magnet strip at the moment, other waste residues are discharged to the ground from the rubber pad, and the purpose of separating the iron waste residues is achieved; and when the rubber pad moves into the rectangular frame body, therotating brush roller sweeps off the iron waste residues attached to the rubber pad to the ground on the lower side of the rectangular frame body, so that the integration of steel slag crushing and separation is realized, frequent transfer of the steel slag is avoided, the labor intensity is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a waste slag crushing and magnetic separation processing device in a steelmaking plant, which belongs to the technical field of steel slag treatment. Background technique [0002] During the production process of steelmaking plants, steel slag containing impurities such as limestone and dolomite will be produced. Steel slag contains a small amount of iron waste slag. In order to separate iron waste slag from steel slag, it is usually necessary to crush the steel slag and then carry out the next separation process. At present, the crushing process and separation process of steel slag are independent of each other. Frequent transfer of materials between the two processes is not only labor-intensive, but also inefficient. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a waste slag crushing and magnetic separation processing device in steelworks t...
