Abstract: 817,577. Magnetic separation. SVIRSKIS. B. April 12, 1956 [April 12, 1955], No 11212/56. Class 117 A magnetic separator for treating slurries or similar wet mixtures comprises a rotor 7 made from thin silicon steel discs clamped between cheek plates 9. The rotor is mounted between adjustable pole-pieces 4, 5 of an electromagnet, and a table 14 leading to a launder 18 receives slurry from a number of feed pipes 13 leading from a hopper 11. A perforated screen 12 prevents oversize particles from entering the hopper, which is provided with a water spray pipe 15 and a rotary agitator 16. A second spray pipe 17 enables the slurry to be further diluted and dispersed as it moves down the table 14. A strongly magnetized pick-off roller 19 of mild or silicon steel engages and is driven by the rotor, and a 'scraper (not shown) of rubber or felt engages the roller from which a launder 20 extends parallel to the launder 18. Magnetic particles attracted from the slurry adhere to the ridges of the rotor until they are attracted to the roller 19, the particles then being removed therefrom by the scraper and passing down the launder 20. The non-magnetic particles normally remain on the table and pass direct down the launder 18 but any partides which are swept upwardly in the valleys of the rotor will be washed downwardly by the spray 21 as they approach the roller and will pass on to the launder 18. More than one rotor may be used, e.g. an H-shaped electromagnet may be provided with a rotor on either side of the central vertical member. Rotors of other contours are specified, Figs. 4-8 (not shown).
