Over-belt electromagnetic separator STE
The STE type electromagnetic separator is designed for automatic separation of ferrous metals from bulk materials transported on belt conveyors or vibrating feeders. The electromagnetic separator protects mills, crushers and other process machines against damage caused by iron parts such as screws, pipe pieces, bearings or crusher teeth. The STE separator is also used to recover valuable ferrous scrap in waste recycling processes.
The STE overband separator is reliable, very durable and designed for continuous operation. The separator is characterized by high metal separation efficiency. The electromagnet used in the separator has a high-quality winding made of aluminum tape with the highest class of insulation. This makes it resistant to high temperatures, very durable and efficient.

Principle of operation of the electromagnetic separator
The electromagnetic separator is usually suspended on a special support structure above the conveyor belt transporting the material. There are two ways to suspend the electromagnetic separator - transversely to the direction of the transported material or longitudinally above the conveyor drive drum. After connecting the power supply to the separator control cabinet, a direct voltage of 110 or 220 VDC is supplied to the electromagnet terminals. The flow of direct current in the winding excites the electromagnet and creates a strong magnetic field that captures metals from the transported material. The captured metals are conveyed by the extractor belt to a discharge chute and then to a scrap container.
