Cascade Magnets
Everest Electromagnetics manufactures pneumatically driven, PLC-based self-cleaning cascade magnets used for removal of ferrous contamination from animal feed, malt, grains and oil seeds. The cascade magnets are provided with three strong, specially designed magnets and four pneumatic cylinders, one for each magnet and one for the automatic 2-way box. When the cascade magnet system is set in operation, the magnets are pressed against the wall by cylinders. The 2-way box is open, allowing the product stream to pass through, while the magnets extract the iron particles and hold them fast. At a given moment, the automatic self-cleaning operation is started. This operation takes only 15 seconds. The flap in the box is lowered and the discharge channel for the iron particles is opened. A proximity switch is triggered which activates a pneumatic valve. This causes the cylinders to push the magnets outside. The iron particles are made free and fall through the discharge channel. The built-in protection prevents the iron particles from entering the product stream. The cleaning cycle can be controlled by PLC or a sequential timer. The system is available in capacities ranging from 5 to 150 T/hour.
