Spiral magnetic field type micro powder magnetic separator

Abstract

The invention discloses a spiral magnetic field type micro powder magnetic separator. The spiral magnetic field type micro powder magnetic separator comprises a rotating cylinder (3), an outer cover (2) externally sleeving the rotating cylinder (3), spiral magnetic rolls (6) fixed in the rotating cylinder (3) and a driving device driving the rotating cylinder (3) to rotate; gaps exist between the rotating cylinder (3) and the outer cover (2) and between the rotating cylinder (3) and each of the spiral magnetic rolls (6); feed inlets (5), from which materials enter a cavity between the spiral rotating cylinder (3) and the outer cover (2), are formed in the upper ends of the outer cover (2); finished product outlets (7) are formed in the lower end of the cavity; iron material outlets (8) are formed in the lower end, corresponding to the spiral magnetic rolls (6), of the rotating cylinder (3); the magnetic field directions of the spiral magnetic rolls (6) incline downward and form a set angle with the horizontal plane; and the spiral magnetic rolls (6) extend to the upper portions of the iron material outlets (8). The spiral magnetic field type micro powder magnetic separator effectively solves the problems that materials and magnetic substance in micropowder, the granularity of which is smaller than 320-meshes, are hard to separate and the like.

Description

technical field [0001] The invention relates to the technical field of separation of materials and magnetic substances, in particular to a spiral magnetic field micro powder magnetic separator. Background technique [0002] During the crushing and grinding process of abrasives and refractory industries, metal iron will be introduced into the materials. Metal iron is a harmful component in refractory materials such as white corundum, brown corundum, mullite, zirconium mullite, etc. High content will reduce the industry. The use performance of materials, as the requirements for the content of magnetic substances in abrasive fine powder and refractory fine powder materials are getting lower and lower, more and more scrap iron materials are produced during the processing of materials, and the magnetic element iron must be removed. An important part of the link. However, after white corundum, brown corundum, mullite, zirconium mullite and other materials are processed into 320 m...
