Magnetic drum BMR
The BMR type magnetic drum is designed for automatic separation of ferrous metals from bulk materials transported by gravity or fed using a vibrating feeder. The magnetic drum protects process machines against damage caused by metal contamination, prevents production downtime and ensures product quality. The BMR drum is also used to recover valuable ferrous scrap in waste recycling processes.
The BMR drum magnet is reliable, very robust and designed for continuous operation. The BMR drum is characterized by high metal separation efficiency. The ferrite or neodymium permanent magnets used in the drum have high coercivity, which makes them difficult to demagnetize. Therefore, the drum magnet has a long service life.

Magnetic drum during operation
Versions of the magnetic drum
- BMR-F type magnetic drum
Made of ferrite magnets with medium magnetic field intensity, designed to remove larger metal contaminants from the transported material, such as screws, bolts and other broken machine parts. - BMR-N type magnetic drum
Made of high-power NdFeB neodymium magnets with high magnetic field intensity, designed to remove small metal contaminants from the transported material, such as bearing balls, metal filings, iron oxides and others with a small adhesion surface to the magnet and weakly magnetically susceptible.
Drum magnet accessories
- Mechanism for adjusting the position of the magnets.
- NORD or SEW gear motor for turning the drum shell.
- Drum shell made of wear-resistant manganese steel.
- TELEMECANIQUE drum rotation sensor.
Working principle of the magnetic drum
The material to be separated is directed to the magnetic part of the drum. Ferrous metals are captured by the magnetic field generated by strong permanent magnets placed under the drum shell. During the rotation of the drum, the cleats placed on the shell carry the captured iron parts in the magnetic field until it disappears, where they fall off automatically into the chute and further into the scrap container. However, the magnetically neutral material flows freely through the drum and leaves the separator.
Why choose our magnetic drums?
Magnetic drums are manufactured in many variants, adapted to the industry, processed raw material and working conditions. High quality of workmanship and effectiveness of our solutions have been recognized by customers all over the world. In addition to the standard catalog offer, we specialize in the production of drums for individual orders, also according to the entrusted design documentation. An innovative technology of water jet cutting of magnets and yokes was developed for the construction of rotating magnetic drums, thanks to which very high precision of magnet assembly was achieved, and consequently high power of the emitted magnetic field. We manufacture drums using the highest quality neodymium, ferrite and high-temperature samarium-cobalt magnets. Magnetix ensures an individual approach to each order and a quick completion date, also for serial deliveries to regular customers.
