what is magnetic separation process？

What are the major factors affecting the iron removal effect of the iron remover? The following is a small series for you to introduce: 1. The effect of the temperature rise of the iron remover on the iron removal effect is proportional to the current, and the current is inversely proportional to the resistance. The resistance of the coil increases with the increase of temperature. Therefore, as the energization time increases, the temperature of the energized coil rises continuously, and the resistance increases accordingly, and the corresponding current will decrease, resulting in weakening of the magnetic field until the dynamic is achieved. balance. Therefore, the good cooling and cooling effect of the electromagnet is an important factor to keep the field strength from sharply decreasing. First, the iron remover with good heat dissipation effect is selected; Secondly, the double dust collector is used in turn to reduce the temperature in time to avoid intermittent iron removal due to the heat of the iron remover when unloading coal. 2. The influence of iron parts near the magnetic field of the iron remover on the iron removal effect The removal of iron by the electromagnetic iron remover is a complicated physical process, and the iron removal effect will be affected after the iron parts around the iron are magnetized. 3. Influence of coal seam thickness on iron removal effect In addition to removing iron from coal in the conveyor belt, the iron remover must overcome the self-weight of the iron piece, the gravity of the coal seam covered by the piece, the friction of the layer against the iron piece, and the magnetization in the field. The additional attraction of iron objects to iron parts. The closer the iron piece is to the magnetic pole of the disk, the greater the suction force, and the smaller the other negative effects. Therefore, it is necessary to keep the field strength of the iron piece from falling down from the coal seam. It is much smaller, so in order to control the temperature rise of the electromagnetic iron remover, and at the same time save energy, a metal detector can be installed before the iron remover. When there is a piece of iron in the conveyor belt, the metal detector sends a signal to the iron remover, which causes strong magnetism in the iron remover to suck up the iron piece. Under normal circumstances, the electromagnetic iron remover only needs to generate a magnetic field that ensures that the iron piece does not fall off. In order to ensure the reliability of the metal detector, the dual detectors can be used in parallel. As long as one detector detects the iron, the electromagnetic separator immediately generates strong magnetism.
