Working Principle Of Dry Magnetic Separator

- Jun 13, 2018 -

     The dry magnetic separator can be divided into strong magnetic field magnetic separator and weak magnetic separator according to the strength of magnetic field. The reason why the magnetic intensity is different mainly because of the different magnetic sources, the magnetic separator is mainly used in the ore dressing production. It is the key to separate the magnetic mineral from the non magnetic mineral and the magnetic difference mineral in the magnetic separation process. Ore dressing equipment.


In order to understand the magnetic separator, we should understand the magnetic separation process first. The magnetic separation is based on the magnetic difference of the different components in the separated material. In the working magnetic field produced by the magnetic separator, the process of separating the different materials by the different particles is different from the magnetic field force and other forces.


     After the ore pulp flows into the tank through the ore feeding box, the ore particles are loose and enter the mining area of the trough. In the action of the magnetic field, magnetic particles are magnetically gathered to form a "magnetic mass" or "magnetic chain". "Magnetic mass" or "magnetic chain" is subjected to magnetic action in the pulp, moving toward the magnetic pole and adsorbed on the cylinder.


     Because the polarity of the magnetic pole is alternately arranged along the rotation direction of the cylinder and is fixed at work, the magnetic agitation occurs when the magnetic pole alternates with the cylinder when rotating with the cylinder, and the non magnetic minerals such as the gangue in the "magnetic mass" or the "magnetic chain" fall off in the turn, and are finally broken down. The "magnetic mass" or "magnetic chain" on the surface of the cylinder is the concentrate. The concentrate is transferred with the cylinder to the weakest magnetic force at the edge of the magnetic system. It is unloaded into the concentrate trough under the action of the flushing flow from the discharge pipe. If it is a full magnetic magnetic roll, the unloading is carried out by the brush roll. The non magnetic or weakly magnetic minerals are left in the pulp with the pulp drained out, that is, the tailings.
