Permanent Drum Separators

Dings Permanent Drum Magnets

Permanent Drums are used in a wide variety of magnetic separation applications. They are designed to continuously remove large quantities of ferrous metal for product purification or to concentrate and reclaim metals in material. Dings Permanent Drum Separators are designed to be easily integrated into existing production line.

Type PC  Magnetic Drum Separators – Do not have a drive motor or housing, mount easily with pillow block bearing and shaft clamp, choice of standard or agitating poles and can be fed by integrating into production systems.

Type FC Magnetic Drum Separators – Come furnished with a drive motor, feed leveler, splitter and housing, multiple drum arrangements are available and easy lubrication with removal of sealed cover plates on both sides of housing.


  • Guaranteed Lifetime Warranty on magnetism
  • Patented Dings Flux Control (DFC) Circuit provides a stronger, deeper and more uniform magnetic field.
  • Rugged, dust-tight construction with stainless-steel shell
  • Totally enclosed motor, motor starter and flanged housing on Type FC
  • Self-aligning roller bearings
  • Easy installation
  • Ceramic VIII magnetic material


Dings Single Configuration Rotating Magnetic Drum

Housing Assembly

The housing assembly is an enclosed structure designed to more easily implement the drum separator into your application. The housing assembly includes a drive, leveler and splitter. The top and bottom of the housing is flanged with a set of mounting holes.

Dings Rotating Magnetic Drum Arrangements

Multiple Arrangements

In these configurations, two or three (or more) magnetic drum separators are used. They can be the same type of drum or differing diameters and magnetic material. The burden will be processed three times in these models, to maximize separation performance.

Custom Designs

Our magnetic solutions experts can custom design any equipment to meet your specific application needs.

Permanent Drums Outperform Electro Models

The Deep Draw Drum’s permanent magnet design outperforms electric-powered drum models by always operating at top efficiency and maintaining a constant gauss or magnetic strength throughout the day.

The electro drum loses some magnetism and separating power as the coil heats up during operation. This reduction in magnetism from startup to the operating temperature reached several hours later can be as great as 30%. The result is a drop-off in metal recovery.

The Permanent Drum Separator emits a very powerful, uniform magnetic field. It costs nothing to operate and does not require a rectifier, generator, switch gear or wiring. There are no magnet coils to burn out.

Permanent Drum Feed Arrangements

The Permanent Magnet Drum Separator can be fed in any position since the internal magnet assembly is adjustable. The drum is easy to install on general contractor I beams. After mounting, the magnet arc is adjusted to match the feed location. Feed position can affect the purity of the recovered metal contaminants. In the top feed position, for instance, ferrous attracted to the drum can entrap nonmetallic material against the drum shell, with both being deposited on the ferrous side of the splitter.

Rotating Magnetic Drum Up and Over Feed

Up & Over

Ferrous is lifted out of the burden and carried up and over the magnet while the nonferrous material drops off the feeder. This feed arrangement minimizes the amount of entrapped nonferrous material and produces a clean ferrous product.

Down & Under

This arrangement has the shortest and most direct transfer area for the ferrous and is often recommended for material with large and heavy pieces of ferrous.

Often used with ferrous material that is weakly magnetic or with feed that contains non-ferrous pieces too large to pass through a reasonable gap.
