Electro bullet magnets
Electro bullet magnets have a powerful bullet-shaped electromagnetic magnet core. They are suitable for filtering medium to large ferrous contaminants from high capacity coarse free-fall bulk flows. Often used in eg. the bulk, animal feed, plastics, ceramics and recycling industries. Electro bullet magnets are automatic cleaning, which makes them suitable for automatic production processes. Because they need a valve box, their installation height is much larger than that of the permanent bullet magnets.
- Electromagnet
- Capture Fe particles from 0.1 mm
- Automatic cleaning (discontinuous)
- Overall height 950 to 2433 mm
- ATEX II 1/2 D possible
Filtering iron contamination out of high capacity coarse product streams
For filtering ferrous contaminants – such as iron and steel – out of granulates, fibres and coarser materials in high capacity non-pressurized pipelines.
Bullet magnets are used in the bulk, animal feed, plastics, ceramics and recycling industries, among others.

Short description
Electro bullet magnets have a large, cylindrical electromagnet core, with a powerful, deeply penetrating magnetic field. The magnetic core has 3 magnetic poles on which trapped ferrous particles are held. The magnetic core can be switched on / off electrically. A valve box is mounted under the pipe magnet in order to be able to automatically discharge the falling ferrous particles.

How does the magnetic filtering work?
Because the magnetic core is located in the middle of the product stream, the bullet magnet has a very high separation yield. The round shape of the housing and the magnetic core (with a 60° top cone) ensures continuous flow and good distribution of the product stream. The product then passes three powerful magnetic fields, where guide strips redirect any product near the outer walls back toward the magnetic core.
The magnets attract passing ferrous particles. The captured particles stick to 1 of the 3 magnet poles, while the purified product flows further.
How does the cleaning / iron discharging work?
Fully automatic cleaning. After you have stopped the product flow, give the start signal for the cleaning. The magnetic core is switched off electrically during cleaning. The valve box automatically discharges the falling ferrous particles.
Cleaning / iron discharging sequence
- Stop the product flow.
- Give the start signal for a cleaning cycle locally, or from your central control.
a. The valve box is switched to iron discharging position.
b. The magnet is switched off.
c. The captured ferrous particles fall off and are discharged via the valve box.
d. The valve box is switched back to production position.
e. The magnet is switched on again. - Restart the product flow.
