Electromagnetism, as it´s name suggests, is the key for this machine to work. It means electricity creates an artificial magnetic field. That is, an iron core is encircled by a conductive wire. When the current goes through the coil, a temporary magnetic field is produced and the ferric particles are attracted.
The electromagnetic overband is supposed to work over a conveyor belt.
Its core is an electromagnet that is surrounded by a belt. When the ferric particles are caught by the electromagnetic block, they get stuck on the band whose purpose is to move the particles away to be placed in a separate container. This way, the overband is always clear and able to continue its job getting more ferric materials.
A WIDE RANGE OF APPLICATIONS
Electromagnetic overbands are suitable to work at any factory where it is essential to separate large quantites of ferric materials. That is, Solid Urban Waste (SUW) plants, Construction and Demolition Waste (CDW) factories, aggregates, scraps, car scraps, Waste Electric and Electronic Equipment (WEEE)… etc.
The machine is designed according to the place where it is supposed to be installed. That is way there are important factors to keep in mind when designing, such as the type of material, its size, how much it is processed each hour, the type of conveyor belt which carries the materials… etc.
