Description

The invention relates to devices for separating materials according to magnetic properties and can be used to enrich finely ground highly magnetic ores.

The purpose of the invention is to increase the separator productivity and reduce the loss of magnetite iron in the tails due to the redistribution of the load between the cleaning sections.

The drawing shows the separator in the section.

The drum magnetic separator contains a stationary magnetic system 1 located outside the cylindrical working body 2 mounted rotatably. Inside the cylindrical working body 2 there are annular partitions 3 located at a distance from the ends of the working body 2, referred to as 1: 8, channels 4, splashing 5 and tray 6. The separator also contains a nonmagnetic fraction receiver 7 and a feeder 8 installed between the partitions 3, which divides working body 2 into three sections 9, 10 and 11.

Drum magnetic separator works as follows.

The raw material in the form of pulp is fed by the feeder 8 in the form of a groove and flows through the tray 6 to the side wall of the cylindrical working body 2 to the receiving section 10. Under the action of the magnetic system 1, the magnetic particles are attracted to the inner surface of the working body 2,

made of non-magnetic material, and rise to its upper part. Then, after leaving the zone of action of the magnetic system 1, the magnetic particles are separated from the surface of the cylindrical working body 2 under the action of gravity and flush water supplied from the squirting 5, fall into the inclined chute 4, which flows into section 11, and through the tray 6 served to the side wall of the working body 2 in the zone of action of the magnetic system 1, where the concentrate is refined (cleaning the magnetic fraction). The concentrate, separated from the surface of the working body 2, falls into the inclined chute 4, and from it into the concentrate receiver (not shown). The non-magnetic fraction flows into the lower part of the working organ, overflowing through the annular partitions 3 from section 11 into section 10, accumulates in the tail section 9 and is discharged into the receiver 7 of the non-magnetic fraction.
