Overband electromagnet SE
The SE type overband electromagnet is designed for removal of ferrous metals from bulk materials transported on belt conveyors or vibrating feeders. The Electro Magnetic Separator protects mills, crushers and other process machines against damage caused by iron parts such as screws, pipe pieces, bearings or crusher teeth.
The SE suspended electromagnet is reliable, very robust 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.

Working principle of the overband electromagnet
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 electromagnet is cleaned of captured metals by disconnecting the power supply. The separator can be suspended on trolleys that allow the electromagnet to be moved outside the conveyor belt for cleaning. After the power is turned off, the captured metals fall directly into a scrap container. Optionally, the electromagnet can be equipped with a extractor belt for automatic metal separation.
Why choose our devices?
The electromagnetic separators produced are available in several variants, adapted to the operating conditions and intended use. Our solutions are delivered to users around the world, where they are used in such extreme working conditions as mines, rock grinding plants, cement plants and installations for recycling various types of waste.
To build separators, we use the highest quality materials and components from our European suppliers, which ensures continuity of supply chains and quick order completion times. The electromagnets used in the separators have a winding made of anodized aluminum tape with additional insulation, thanks to which our solutions have the highest insulation class C up to 300°C. This ensures high thermal resistance and long service life of our solutions.
The power supply and control cabinet, adapted to cooperate with the superior control system, is responsible for power supply and control of the separator's operation.
Our technical advisors provide professional advice at the stage of selecting the type of separator, the necessary additional equipment, and participate in the design of the installation of our devices in industrial installations.
Electromagnet price
Based on the operating conditions specified by the Customer, the appropriate type of overband electromagnet is selected and its price is determined, which depends primarily on the installed power. Depending on the ambient temperature and the transported material, electromagnets are offered without cooling (cooling by natural air circulation) or with oil cooling. A more expensive option is an electromagnet cooled by oil due to the different design of the windings and housing. Special painting in classes C3, C4, C5M involves an additional charge to the price of the device. Any color can be selected from the RAL palette at no additional charge.
The delivery time of the device on request is standardly 6 - 8 weeks. We also fulfill orders with an accelerated deadline. Magnetix also has a large warehouse of separators available immediately.
Magnetix also carries out comprehensive deliveries of electromagnetic separators including the design of the installation, steel structures, control systems and mechanical and electrical assembly. The price of a comprehensive separator delivery with assembly is calculated individually and depends on the complexity of the installation and the scope of work.
