Abstract

FIELD: mining industry. SUBSTANCE: chute 1 mounted on frame 8 is made V-shaped with the bottom inclined to the side of discharging the magnetic product. The coils of electromagnets 5 adjoining chute 1 are ensured with power from source 9 through thyristor regulators. A vertically shifting screen is mounted on the output of chute 1 of the magnetic product. Charger 2 with exhaust pipe 3 fastened to its lower part along chute 1 is located over chute 1. Magnets 4 whose like poles face each other are mounted on both sides of the pipe. The pulp coming from charger 2 passes in pipe 3 through the magnetic field of magnets 4. The magnetic particles flocculate and, getting into chute 1, are shifted to the screen under the action of the pulsating magnetic field of electromagnets 5. Non-magnetic particles are washed out by the water flow and the pulp and are poured off from both sides of chute 1. The required density of the concentrate and the contents of iron in the overflow of chute 1 are obtained by regulating the screen position. EFFECT: enhanced quality of the magnetic product at the expense of lengthening the zone of discharging the non-magnetic product. 2 cl, 2 dwg
