Power Stations

Magnetic Separators and Metal Detectors are key equipment in any power station, removing problematic and damaging tramp metal from conveyed fuel (including biomass, coal, refuse, wood, etc).  Successful removal of such large tramp metal protects against costly damage of crushers and other processing machinery and potential plant downtime for emergency repairs.  For larger bulk handling terminals (sending and receiving coal, wood, biomass, etc), Bunting design large, bespoke Electro Overband Magnets.

Tramp metal causes damage to conveyors, crushers, screens and other processing equipment.  The optimum solution to prevent tramp metal damage is the installation of a combination of magnetic separators and metal detectors.  Each technology fulfils a specific separation objective.

Typical Applications:

Magnetic Separators are used to remove ferrous metal contamination:

  • Suspending a self-cleaning Overband Magnet or manual-clean Suspension Magnet across or over a conveyor. Both Overband and Suspension Magnets are available in permanent and electromagnetic designs.  Metal is lifted off the conveyor belt and either held on the magnet face or automatically discharged.  Many of the designs for power station are bespoke due to the wide conveyors, high burden depths, conveyor speeds, and ferrous metal separation specification;
  • Replacing a conveyor’s head pulley with a Pulley Magnet. Ferrous tramp metal is attracted to the magnetic field and deposited underneath the conveyor out of the product stream.  Ideally suited when suspended a magnetic separator is not possible, but often used in conjunction with a suspended magnetic separator when the burden depth is particularly deep;
  • Feeding material onto a heavy duty Drum Magnet either directly or via a vibratory feeder. Magnetic material is attracted to the strong magnetic field and deposited underneath and away from the product;
