Abstract (en)
[origin: US4296865A] A magnetic separator having two rotating magnetic drums of opposite polarity which form between them a working air-gap, and having directionally magnetized block magnets on each side of both end-faces of the magnetic drums in a closed magnetic circuit, the magnets being connected together on one side of their poles, in pairs with unlike poles, by means of soft-iron parts, and being provided, on the other side, with pole shoes in which are mounted soft-iron parts designed as axes, the drums each being arranged in a housing comprising slide plates which are located in the working air-gap and which converge at the inlet and diverge at the outlet, the said drums comprising axial grooves distributed radially around their peripheries, or having peripheries of star-shaped cross section.
