The magnetic head pulley replaces the drive pulley at the end of conveyor belts. In view of the wide variety of conveyor belt types, the magnetic 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.
The version with permanent magnets are fitted with powerful and An-Isotropic Hard ferrite Magnets /high intensity Nd - Feb Rare Earth 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.
Finally as the belt leaves the magnetic pulley, the magnetism dissipates and the unwanted contamination falls from under the belt into a separate receptacle. |
