Permanent Magnetic Drum Pulley
The magnetic Drum pulley replaces the drive pulley at the end of conveyor belts. In view of the wide variety of conveyor belt types, the drum pulley are supplied made to measure and ready for installation. As the figure clearly show, the magnetic head roller extracts the iron particles from the material flow and carries them to the underside of the belt where they are removed and collected. Head roller magnets for conveyor belt are supplied in permanent magnets.
The version with permanent magnets are fitted with powerful and An-Isotropic Hard ferrite Magnets /high intensity Rare Earth Nd-Fe-B Magnets and operate without the need for power supplies. The magnet system is available in two types: with Longitudinal polar field distribution for use with low levels of iron contamination and thin material layers, and with lateral polar field distribution for greater material thickness and larger iron particles.
