When using a plate magnet in a chute (Fig. 2.4), tramp iron is attracted and trapped by magnetic force, whereas the remaining materials (non-magnetic portion) pass in front of the magnetic plate without being absorbed. The magnetized plate must be periodically inspected and cleaned because its efficiency decreases if tramp iron particles ...

The Reading Rare Earth Magnetic Drum (RED) uses a unique 5 pole magnetic element to generate a field intensity in excess of 0.7 Tesla on the drum skin. The magnetic element design affords the maximum field gradient and the 5 poles enables additional cleaning of the magnetic stream. This gives a very selective separation at high throughputs compared …
