Magnetic separation equipment refers to the use of magnetic equipment to separate magnetic materials from other materials according to the magnetic characteristics of materials. The equipment used for such operation is called magnetic separation equipment, which is generally used for the production and screening of magnetite and other magnetic minerals. Magnetic separation equipment is also called magnetic separator, magnetic separation machinery, etc.
Under the action of the magnetic field, the magnetic particles gather to form a "magnetic cluster" or "magnetic chain". The "magnetic cluster" or "magnetic chain" moves to the magnetic pole under the action of the magnetic force in the pulp and is adsorbed on the cylinder. Because the polarity of the magnetic pole is alternately arranged along the rotation direction of the cylinder, and it is fixed when working, "magnetic mass" or "magnetic chain" will produce the phenomenon of magnetic stirring when rotating with the cylinder due to the alternation of the magnetic poles, and the gangue and other non-magnetic minerals mixed in the "magnetic mass" or "magnetic chain" will fall off during the overturning, and finally be absorbed in the "magnetic mass" or "magnetic Lotus" on the surface of the cylinder It's concentrate. The concentrate turns to the weakest part of the magnetic system edge with the cylinder, and is discharged into the concentrate tank under the action of the flushing water from the discharge pipe. Non magnetic or weak magnetic minerals are left in the pulp and discharged out of the tank with the pulp, that is, tailings.
Magnetic separation equipment can separate many minerals, such as magnetite, limonite, hematite, manganese siderite, ilmenite, wolframite, manganese ore, manganese carbonate, metallurgical manganese ore, manganese oxide, iron ore, kaolin, rare earth ore, etc. Magnetic separation process is in the magnetic field of magnetic separator, with the help of magnetic and mechanical force on the role of ore particles to achieve separation. Different magnetic particles move along different trajectories and are separated into two or several separate mineral processing products. The magnetic separator is suitable for wet magnetic separator of magnetite, pyrrhotite, roasted ore, ilmenite and other materials with particle size less than 3 mm. It is also used for iron removal of coal, non-metallic ore, building materials and other materials.
