The magnetism in a Permanent Magnetic Pulley is generated by internal assembly of magnets enclosed in non magnetic Stainless Steel shell. The steel shaft is extended on both sides. One side is provided with Key-way. The Pulleys have a face width of 50 mm to 100 mm more than the belt width. The magnetic strength of the pulley depends on the diameter and also quality of magnets used.Pulleys with Rare Earth Magnets can handle depths up to 300 mm.
Pulley width is determined by width of conveyor belt to be used. Diameter depends on depth of material and speed of the conveyor. It can be designed to suit customer’s specific application.
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.
