Product Description:

Magnetic Separator is also names wet magnetic separator, magnetic drum separator, china magnetic separator or magnetic separator machine. Magnetic separator is a kind of equipment that separate magnetic metals from other impurities according to the magnetic characteristics of the metal materials. Magnetic separator is widely used in resource recycling, timber, mining, ceramic, chemical and other fields, and is suitable for wet magnetic separation of magnetite, pyrhotite, roasting ore, ilmenite, and other materials with particle size less than 3mm. In addition, magnetic separator is used to de-iron for coal, non-metal ore and building materials. So we can say that magnetic separator is one of the most widely used machines.

The Structure of Magnetic Separator:

Its magnetic system is a ring-shape chain closed magnetic circuit with energizing coils made of copper tube and cooled internally by water. Grooved plates made of magnetic conductive stainless steel are used as magnetic matrix. It possesses the following advantages: short magnetic circuit, little magnetic flux leakage, high magnetic intensity, low energy consumption, fine beneficiating results, simple structure and easy to maintain.

The Working Principle of Magnetic Separator:

1. The pulp flows into cell body from the pulp box, and under the water flow of the feeding spray pipe, the mineral grain will go into the feeding area of the cell body in the loose condition. In the magnetic field of magnetic separator machine, the magnetic ore particles will have magnetic gathering and form magnet group or magnet chain which is influenced by the magnetic force inside the pulp and moves to the magnetic pole of the wet magnetic separator or magnetic drum separator and finally is absorbed onto the cylinder.

2. Since the polarity of the magnetic pole along the rotary direction of the cylinder is alternately arranged and is fixed during the working process, when the magnet group or magnet chain rotate with the cylinder, it will have magnetic mixing due to the alternation of the polarity, as a result of which, the non magnetic ore such as gangue mixed up with the magnet group or magnet chain will split away off in the stirring, and the magnet group or magnet chain that is finally absorbed onto the surface of the cylinder is concentrate.

3. The concentrate rotates to the edge of the magnetic system where the magnetic force is the weakest along with the cylinder, and under the water flow of the discharging spray pipe, it will be discharged to the concentrate chute. If the roller is all magnetic roller, the ore discharging is completed by brush roll. The non magnetic and weak magnetic minerals are kept in the pump and are discharged from the chute with the pulp to become tailing.
