Drum Separators

Drum-in-Housing Magnets

The drum magnet design allows for continuous cleaning of the magnet system, accomplished by the rotation of the drum itself around the magnetic element. Similar to the cleaning belts on MSI’s self-cleaning suspended magnets, the rotating drum features wipers that clear away ferrous material collected on the drum surface. Like MSI’s pulleys, drum-in-housing magnets are available in two different configurations: radial and axial designs.

• AXIAL DESIGN is the workhorse for magnetic drum applications and is used widely across a number of industries. This design provides agitation, improves separation, and can provide good reach into deep burdens, as needed.
• RADIAL DESIGN is typically used for the separation of fine ferrous from fine burdens, like magnetic particles from sand.

Separation behavior for both axial and radial designs is similar to magnetic head pulleys, with added advantages:

1. the separator does not require a conveyor system, saving money;
2. in larger diameters, drum separators can be built stronger and more economically than pulleys;
3. the damper can be adjusted, and the magnet can be used both to separate and to meter burden flow; and
4. optional removable shell: the magnetic element is separate from the rotating shell, so in abrasive applications the design allows for shell replacement.

MSI’s FREE TESTING allows our customers to make informed decisions and purchase with confidence.

Drum-Only Magnets

Drum magnets (without the housing) are also available. These magnets are often used at the end of pulleys or vibratory conveyors, when customers already have existing chutes, and in other specialized situations where stationary separators are inadequate.
