Abstract
A high-intensity magnetic separator operating in a wet environment for separating magnetic particles from a fluid material comprises a separating unit which comprises a vertically extending housing having side walls defining a separating chamber, valved ducts for alternately circulating the fluid material and a washing liquid vertically downwardly through the separating chamber, and permanent magnets arranged adjacent the side walls of the housing for generating therebetween a magnetic field extending perpendicularly to the direction of circulation of the fluid material in the separating chamber. The permanent magnets and the housing are displaceable relative to each other between a first position in which the permanent magnets are so close to the side walls of the housing that the magnetic field is intense enough to retain the magnetic particles in the separating chamber while the fluid material is circulated therethrough in a separating phase, and a second position wherein the side walls are so remote from the permanent magnets that the magnetic field is sufficiently attenuated to release the magnetic particles retained in the separating chamber while the washing liquid is circulated therethrough to evacuate the magnetic particles from the chamber in a washing phase.
