One side is provided with Keyway. The Pulleys have a face width of 50 to 100 mm more than the belt width. The magnetic strength of magnetic pulley depends on the diameter and also quality of magnets used. Pulleys with Rare Earth Magnets can handle depths upto 300 mm.
Pulley width is determined by the 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 application.
