Heavy Duty Magnetic Drum Pulley Assemblies

Heavy Duty Magnety Drum Pulley AssembliesStraight face drum pulley assemblies with permanent ceramic magnets inside a stainless steel rim that meet CEMA (Conveyor Equipment Manufacturers Association) application standards for use with conveyor belts rated up to 750 PIW (Pounds per Inch of Belt Width) or 61 kN/m.


The DODGE Magnetic Envelope is the best because the magnets are arranged in a proprietary pattern that projects the flux density out several inches from the rim. The alternating positive and negative forces tumble iron particles and pieces within the heap of bulk material, bringing them directly against the belt by the time they reach the 12 o’clock position of the drum. The gauss is highest at the rim surface, ranging from 1,400-1,800 depending upon pulley size. The envelope holds the iron tightly until it reaches the 7 o’clock position and the moving belt peels it away from the magnetic drum. Centrifugal force “shoots” the nonferrous bulk product off at the 2-3 o’clock position. HE (High Endurance) 14-degree taper bushings impart the lowest installation bellows stress of any taper bushing shaft mounting system for 2 hub pulley applications.

Key Industries / Applications

Head pulleys for removing iron materials and fines on bulk belt conveyors used in mining, aggregate, coal, electric generating plants, transportation ports and terminals, woodchip making, solid waste, concrete and wood recycling plants, food processing, and iron and steel mills.
