Magnetic separator is used to recycle powdered granules to remove iron powder and other screening equipment. After the slurry flows into the tank through the feeding box, under the action of the water flow from the mine spray pipe, the ore particles enter the feeding area of the tank in a loose state. Under the action of the magnetic field, the magnetic mineral particles are magnetically aggregated to form "magnet clusters" or "magnet chains". The "magnet clusters" or "magnet chains" move to the magnetic poles in the pulp and are adsorbed on the cylinder. Since the polarities of the magnetic poles are alternately arranged along the rotation direction of the cylinder and are fixed during operation, the "magnet cluster" or "magnetic chain" will produce magnetic stirring phenomenon due to the alternating magnetic poles when the cylinder rotates, and become mixed The gangue and other non-magnetic minerals in the “magnet cluster” or “magnet chain” fall off during turning, and the “magnet cluster” or “magnet chain” that is finally attracted to the surface of the cylinder is the concentrate.
Permanent magnet drum type magnetic separator is used to separate fine-particle magnetic minerals, or to remove magnetic minerals mixed in non-magnetic minerals. The magnetic field intensity on the surface of the permanent magnet cylinder magnetic separator is much higher than that of the ordinary permanent magnet magnetic separator. It is easy to operate, manage and maintain, and has obvious energy-saving performance when used in various concentrators.
