Magnetic separator: It mainly relies on magnetism to select the magnetic substances in the garbage, so as to achieve the function of purity of organic matter and recyclability of scrap metal. It is suitable for wet magnetic separation of magnetite, pyrrhotite, roasted ore, ilmenite and other materials with a particle size of less than 3mm, and also used for iron removal of coal, non-metallic ore, building materials and other materials.

In the magnetic field of the magnetic separator, the separation of iron powder is realized by the action of magnetic force and mechanical force on the ore particles. Different magnetic ore particles move along different trajectories and are sorted into two or more separate beneficiation products.

Magnetic separator is one of the most widely used and highly versatile models in the industry. It is used to remove iron powder from powdered granules. Magnetic separators are widely used in resource recovery, wood industry, mining, and kilns. Industrial, chemical, food and other factories.

5. It can effectively absorb 0.1-50 kg of ferromagnetic materials mixed in non-magnetic materials.

working principle:

When a metal object passes through the induction coil of a metal detector, under the action of the alternating electromagnetic field, the metal object has good conductivity and produces a large eddy current loss, which reduces the amplitude of the oscillator and is detected. At this time, the metal detector sends a signal to the program cabinet. After a delay of 6s, the electromagnetic starts to work. At this time, the metal object on the belt conveyor just reaches the bottom of the electromagnetic separator, and the magnetic metal object is picked up by the separator and removed after about 3 seconds. The electric trolley on the iron brings the iron remover to the material recovery box, the electromagnet demagnetizes the metal parts, and then the electric trolley brings the iron remover back to the top of the belt. If the electromagnetic separator receives a signal from the metal detector during the process of releasing the iron, it will immediately return to the top of the belt with excitation and wait for the next metal object to be attracted before releasing the metal object. However, non-magnetic metal objects (such as manganese steel) are sometimes mixed in the ore. At this time, although the metal detector can still detect this non-magnetic metal object, the iron remover cannot remove it. Therefore, a second metal detector should be designed and installed 5m behind the iron separator. When the second metal detector detects metal, the time relay delays the belt conveyor to stop, and the operator picks up the non-magnetic metal at the set position. , Put it in the recycling bin.
