Head Pulley Magnets, Head roller magnets
Head Pulley Magnets provide continuous self cleaning on products conveyed by belt. As product is conveyed along the belt it reaches the head pulley and enters the magnetic field where metal contaminants are attracted and held tightly to the belt surface. As the belt is conveyed around the magnetic pulley, metal contaminants are held in place until they pass through the magnetic field where they are safely discarded separate from the clean product.
A diverter is typically installed below the pulley to direct the metal contaminants away from the cleaned product.
Head Pulley Magnets
The magnetic head roller is a replacement for the drive roller at the end of a conveyor belt. In view of the wide variety of conveyor belts, the head roller magnets are supplied made-to-measure and ready for installation.
As can clearly be seen from the illustration, the magnetic head roller pulls the ferrous particles out of the material flow and carries them through to the underside of the belt where they are dropped and collected.
In the standard versions, the head roller is supplied with a longitudinal pole distribution which is suitable for thicker material flows and larger ferrous particles.
If required, head rollers can also be supplied with transverse pole distribution for applications where there is less ferrous contamination and thinner material flows. A combination of a head roller magnet and an overhead system gives perfect separation.
