Is there a better way to improve the effect of the suspension magnetic separator than multiple iron removals?

Suspension magnetic separator belongs to a device capable of forming strong magnetic field absorption. The purpose of using this device is to clean up the mixed iron and other magnetic materials from the raw materials to ensure that the mechanical equipment such as the crusher in the conveying system can work normally Operation.

The traditional form of suspension magnetic separator is usually not efficient in removing iron. In order to improve the effect of iron removal, the unit usually adopts the method of removing iron twice or three times, but this cannot fully meet the requirements of the factory. The main reason is that the iron material in the bottom of the coal seam is relatively small due to the small magnetic force, and also the pressure of the upper coal, so it is not easy to be efficiently sucked out. In order to improve the iron removal effect, the suspension magnetic separator manufacturer will use a “short-time strong excitation” method to improve the effect when designing the sensor, that is, the sensor is installed on the front side of the electromagnet pole shoe and below the conveyor belt. The purpose is to detect the distance between the pole shoe by the sensor, and suck up more weak magnetic material and then transmit it to the strong excitation rectifier through the sensor, so that when the magnetic material passes under the pole shoe, a Short-term power supply voltage, resulting in strong magnetic current. Electromagnetic attraction will increase suddenly in a short time, so it can absorb the buried magnetic material and restore the voltage to the normal power state. The “short-term incentive” method has greatly improved the situation of poor iron removal effect and has great application potential.

The purpose of installing the sensor device in front of the pole piece is to prevent the electromagnetic field of the electromagnet from being disturbed. Under normal circumstances, if the iron material is in the upper or middle part of the coal seam, as long as the iron is not buried in the bottom of the coal seam, the sensor is not allowed to send valid signals and send valid signals. This enables the dump iron remover to better complete the iron removal task.
