Elektromag Magnetic Pulleys are generally used as the head pulley of a conveyor for separating iron pieces from conveyed material. Elektromag Magnetic Pulleys are used for all kinds of bulk materials, such as brown and pit coal, coke, like-stone, cement, rock salt, potash, chamotte, blast furnace, and steel mill slag, foundry sand, gravel, sand, synthetic granulates, grain and feedstuff. They can also be fitted as drive or return pulleys to the discharge end of rubber conveyor belts of existing installations at a later stage.
ELEKTROMAG Magnetic Pulleys are mainly designed to remove large iron pieces, such as bolts, screws, wire, strips and tools which could damage conveyor belts, brake sieves, crushers or processing machines.
Other Type of separating magnets are available for separating fine iron. In the event of slag separation they server – depending on the granulation – for parting magnetic and non-magnetic components.
METHOD OF OPERATION
The magnetic field produced is effective on the entire surface in the range of the conveyor belt. The magnetizable iron pieces contained in the conveyor material are influenced by the magnetic field and drawn on the conveyor belt. The iron pieces follow the run of the conveyor belt until they loosen from the magnetic field and, parted from the conveyor material, are discharged in the belt’s run direction underneath the magnetic pulley.
