Problems solved by technology

Some non-magnetic minerals are tightly wrapped by the agglomerates formed by magnetic minerals before they enter the tailings with the slurry flow. Under the action of the limited wrapping angle of the magnetic system, the flipping effect of the magnetic system cannot fully remove the non-magnetic materials, thus causing magnetic General inclusion of selection process
[0003] The magnetic system structure of the dry magnetic separation is basically the same as that of the wet type, but the box structure is relatively simple. After entering the magnetic field, the magnetic material...

Abstract

The invention relates to a separation method and equipment for magnetic matters, in particular to a power magnetic levitation separation and enrichment method and equipment. According to the power magnetic levitation separation and enrichment method and equipment, an alternating power magnetic system changing periodically is arranged in a fixed cylindrical barrel in a manner of rotating around the axis of the barrel for 360 degrees; the alternating power magnetic system does rotary movement around the axis of the barrel at a certain angular speed; magnetic matters in separated minerals on the outer side of the barrel form needle-shaped suspended magnetic polymers which are distributed on the outer surface of the barrel; the needle-shaped suspended magnetic polymers move on the outer surface of the barrel along the rotary direction opposite to that of the power magnetic system to form a magnetic fluid, and are swung and overturned under the effect of the alternating power magnetic system to gradually remove un-magnetized slime and non-magnetic minerals from the needle-shaped suspended magnetic polymers, and further, the magnetic polymers get rid of the acting force of the alternating power magnetic system through a magnetic matter unloading device and are collected. The separation and enrichment method and equipment are unique in design and high in separation and enrichment efficiency.

Description

technical field [0001] The invention relates to a separation method and equipment for magnetic substances, in particular to a dynamic magnetic levitation separation and enrichment method and equipment. Background technique [0002] At present, wet magnetic separation methods widely used include countercurrent, semi-countercurrent and downstream magnetic separation technologies. The schematic diagram of the separation principle is attached. figure 1 , attached figure 2 , attached image 3 As shown, the ore pulp is fed into the self-sufficient ore tank, and naturally flows into the sorting tank. When the ore pulp flows into the range of the magnetic wrapping angle, the magnetic mineral particles are quickly reunited and adsorbed on the surface of the cylinder under the action of the magnetic field, and are brought together with the rotation of the cylinder. Out of the magnetic field area, it enters the magnetic material hopper and is discharged from the magnetic separator u...
