Technical Field

Background

The working effect of the magnetic separator is greatly influenced by the operating process factors, and the feeding concentration and the coal slime content in the fed materials are controlled in a proper range. When the content of the magnetic substances in the dilute suspension solid is lower than 50%, the feed concentration of the magnetic separator is less than 20%, and the optimal concentration is about 15%; when the content of the coal slime in the dilute suspension solid is low, the feed concentration of the magnetic separator can be improved to 20-30%. The magnetic separator aims to solve the technical problem that the recovery efficiency of the magnetic separator is influenced by overhigh or overlow concentration of feed materials of the magnetic separator. However, when the solid content concentration in the ore pulp is too high, solid substances (mainly coal slime and magnetic substances) are easily deposited in a flow channel of a tailing tank, flow of the ore pulp forms retardation throttling, local flow overspeed is caused, the phenomenon of local water surface overturning is commonly called 'overturning', magnetic substances in tailings break away from the magnetic separation roller to be adsorbed, and finally medium loss is caused.
