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 …

Magnetic separation is a versatile technique used in sample preparation for diagnostic purpose. For such application, an external magnetic field is applied to drive the separation of target entity (e.g. bacteria, viruses, parasites and cancer cells) from a complex raw sample in order to ease the subsequent task(s) for disease diagnosis.

Magnetic drum separators come in many different styles. Tramp iron drum separators usually use a magnet design referred to as a radial type. In such a unit the magnet poles alternate across the width of the drum and are of the same polarity at any point along the drum's circumference. The magnet assembly is held stationary by clamp bearings ...

As material reaches the drum, the magnetic field attracts and holds ferrous particles to the drum shell. As the drum revolves, it carries the material through the stationary magnetic field. The nonmagnetic material falls freely from the shell, while the magnetic particles are held firmly until they are carried out of the magnetic field.
