Permanent Magnetic Drum Separator | Jupiter-Delhi

Magnetic Drum Separator

Jupiter Drum Separators remove both large and small pieces of iron contaminants from material processing lines. Powerful permanent magnets enable more efficient separation performance for a broader range of applications than ever before.


Magnetic Drums are constructed with a 180-degree stationary magnet system, around which a cover revolves. Material is fed onto the drum cover at the leading point of the magnet section. Magnetic materials will adhere to the drum cover as it revolves and will then be discharged behind the normal trajectory. Non-magnetic materials will free-fall forward following their normal trajectory.

For applications that may involve co-mingled materials, Jupiter Magnetics can offer a magnet system that features an alternating pole arrangement as shown in the image below. This magnet system enables the entrapped ferrous materials to flip over the magnetic poles as they move over the surface of the drum and become free from the non-metallic product.



Permanent Magnetic Drums Separators are designed for the continuous extraction of ferrous materials from a product being fed uniformly on to the face of the magnetic drum. As the material is fed onto the magnetic drum, ferrous materials are extracted and are firmly held to the drum face until they move away from the magnet's influence and discharge, leaving any non-ferrous materials to free fall.

Permanent Magnetic Drums have a 180-degree stationary magnet system within a revolving cover. The magnet system is constructed using fully stabilized strontium ferrite permanent magnets. The magnets are mounted on heavy-duty back plates, to optimize the magnetic strength directed at the product stream. This not only enhances the Drum's performance but also reduces the magnetic fields in the shaft and bearings, helping to extend their service life.


For applications that require a much greater level of extraction, Permanent Drum Magnets can be constructed using the highest grade of Neodymium Iron Boron magnets. High-Intensity Rare Earth Drums Separators are capable of extracting fine ferromagnetic materials, which may not be extracted using a standard Permanent Drum Separator. Rare Earth Magnetic Drums Separators are most often fitted into totally enclosed housings described in more detail below.


In applications where the product needs to be kept from external contamination or where the dusty product must be contained from escaping into the working environment, Permanent Magnetic Drums Separator can be supplied with totally enclosed housings.

Housings can be manufactured in robust mild steel or stainless steel. Inspection covers, aspirators, and diverter plates are provided as standard.

  • The axial pole design gives continuous high field strength at the separation zone. The effective magnet width is maximized thus ensuring even cover wear and minimum burden depth of material.

  • The bipolar alternate pole arrangement ensures a cleaner separation of ferrous and non-magnetic materials. This is because materials, which may be entrapped are allowed to roll over the face of the drum, helping to release the non-metallic materials from the magnetic materials being extracted.

Typical applications for Jupiter’s range of permanent and rare earth magnetic drums separators are:
  • Removal of ferrous contaminants from glass cullet

  • Removal of ferrous particles from powder or granular materials

  • Recovery of ferrous materials from incinerator bottom ash

  • Removal of fine ferrous particles from foodstuffs

  • Recovery of ferrous metals from municipal solid waste
