Performance characteristics of self-unloading iron remover:
1. The magnetic performance is stable and the magnetic circuit design is unique. This iron remover has strong magnetism, high magnetic field gradient, and the suction force is much greater than the national standard iron remover;
2. The waist drum-shaped roller with automatic deviation correction function and the fully sealed cast steel bearing seat ensure that the iron separator can work without failure for a long time in various harsh environments.
3. It is widely used in industries such as construction waste treatment, sorting of iron in decoration waste, and screening of iron-containing metals in stale domestic waste.

Working principle of construction and decoration waste iron remover:
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 generates 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 6 seconds, the electromagnetic starts to work. At this time, the metal objects on the belt conveyor just arrive under the electromagnetic iron remover. The iron remover picks up the magnetic metal objects and removes them after about 3 seconds. The electric trolley on the iron tool brings the iron remover to the material recovery box, the electromagnet demagnetizes the metal parts and puts them down, and then the electric trolley brings the iron remover back to the top of the belt. If the electromagnetic iron remover receives a signal from a metal detector while it is releasing iron, it will immediately drive the excitation back to the top of the belt, wait for the next metal object to be sucked, and then release the metal object.
There are sometimes non-magnetic metal objects (such as manganese steel) mixed in construction waste, decoration waste and ores. Although the metal detector can still detect the non-magnetic metal object, the iron remover cannot remove it. Therefore, a second metal detector should be designed and installed 5m behind the iron remover. When the second metal detector detects metal, the time relay delays the belt conveyor to stop, and the operator goes to the set position to pick up the non-magnetic metal. , put it in the recycling bin.
