Abstract

The invention relates to magnetic enrichment and m. used to enrich highly magnetic ores. The purpose of the invention is to demonstrate the efficiency of the separation process. A tub with a slurry with the ability to move is placed a working body with polygradient elements, made in the form of parallel cables (T) 5. The latter are tensioned on the drive and driven rollers (P) 6 to form an endless belt. Polygradient elements are made in the form of individual permanent magnets (M) connected with a gap between them by nonmagnetic yarns, the free ends of which are fixed between T 5 with sagging. An unloading device in the form of an electromagnetic P 3, whose width is equal to the distance between T 5, is installed between the branches of the tape. With the help of P 6, T 5 with the threads on which M are fixed are moved. The latter attract the magnetic particles and the output t them out of the bath. When passing over P 3, particles are removed from M and discharged into the receiver. Purified magnetic particles pulp flows out of the bath. 1 3.p. f-ly, 3 ill. & cl

FIG. 2

The invention relates to the field of magnetic enrichment and can be used to enrich highly magnetic ores.

The purpose of the invention is to increase the efficiency of the separation process.

FIG. 1 shows a separator, a cross-section; in fig. 2 - the same general view; in fig. 3 - polygraph elements tensioned on the cable.

The separator includes a working body with polygradient elements 1, placed in a bathtub with the ability

displacement, bath 2, loading device (not indicated), discharge device 3, while the polygradient elements are made in the form of separate permanent magnets connected with a gap between them by nonmagnetic threads 4, the magnets facing the same poles together, the working body is made in the form of parallel cables 5, pulled on the drive and driven rollers 6 with the formation of a closed endless tape, with the free ends of the threads fixed between the cables with slack, the discharge device for the magnetic material is made in the form of an electromagnetic roller installed between the branches of an endless belt, and the width of the roller is equal to the distance between the cables 5.

The separator works as follows.

Through the bath 2 pass the pulp containing highly magnetic material. The posture of the rollers 6 drives the cable 5 with the threads 4, on

magnets 1 are fixed, moving the magnets in the bath to attract magnetic particles and take them out of the bath. The passage under the discharge roller 3, the particles are removed from the magnets and unloaded into the receiver. Purified magnetic particles from the pulp flows out of the bath 2.

Claims (2)

1. Magnetic separator, which includes a working body with polygradient elements, placed with the ability to move in a bath with pulp, loading and unloading devices, characterized in that, in order to improve the efficiency of the process. And the separation of highly magnetic materials, poly- gradient. elements are made of separate permanent magnets mounted by rows, connected with a gap between them by nonmagnetic strings, with the magnets facing in a row of each other. to the other with the same poles, and the working body is made in the form of parallel cables, tensioned on the drive and driven rollers to form a closed endless belt, while the free ends of the threads are fixed between the cables with slack. 2. A separator according to claim 1, wherein the discharge device is made in the form of an electromagnetic roller installed between the branches of an endless belt, the width of the roller being equal to the distance between the cables.
