Steel slag horizontal roller mill iron removing device and iron removing method thereof

Abstract

The invention provides a steel slag horizontal roller mill iron removing device. The steel slag horizontal roller mill iron removing device comprises a cylinder body, as well as a compression roller, a material guiding plate and a material scraping plate which are arranged inside the cylinder body, wherein a wedged space is formed between the compression roller and the side wall of the cylinder body; the material guiding plate is arranged by forming a certain inclined angle with the axial direction of the cylinder body; the material scraping plate is fixedly arranged in the cylinder body and makes contact with the inner side wall of the cylinder body; the material scraping plate is positioned above the material guiding plate; a non-magnetic roller is arranged between the material scraping plate and the material guiding plate; a permanent magnet is fixedly arranged inside the non-magnetic roller; an iron recovering mechanism is arranged below the non-magnetic roller. The steel slag horizontal roller mill iron removing device is simple in structure, small in size and convenient to mount; grinding and iron removal can be performed at the same time, a magnetic metal body in the grinding process of a horizontal roller mill can be effectively removed, the abrasion of the cylinder body and the compression roller due to enrichment of the magnetic metal body is avoided, and further the service life of the steel slag horizontal roller mill iron removing device is prolonged; compared with an external circulation iron removing mode, the steel slag horizontal roller mill iron removing device provided by the invention has the advantages that the wear of equipment is greatly reduced, and the maintenance quantity of the equipment is reduced, so that the maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a steel slag horizontal roller mill deironing device and a deironing method thereof. Background technique [0002] Horizontal roller mill is based on the working principle of material bed crushing, skillfully combines the main advantages of ball mill and roller press, and uses medium extrusion force at a medium surface speed of the roller to feed the material into the equipment at one time to achieve multiple The secondary extrusion grinding avoids the technical problems of vertical mills and roller presses, and finds a new way to fully utilize the energy-saving potential compared with vertical mills and roller presses. It is suitable for grinding cement clinker, slag, fly ash, limestone and other materials, and can be used as pre-grinding equipment or final grinding equipment. [0003] However, horizontal roller mills are limited in the field of steel s...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem that the existing horizontal roller mill cannot remove iron during the steel slag grinding process, resulting in high abrasiveness of the cylinder body and pressure roller, and greatly reduced service life
