Permanent bullet magnets have a powerful bullet-shaped ferrite 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. Permanent bullet magnets have a lower installation height compared to electro bullet magnets. Yet, you have to clean them manually, where this is done automatically with the electro bullet magnets.
Ferrite magnet
Capture Fe particles from 50 µm
Manual cleaning (wipe off)
Overall height 420 to 1300 mm
ATEX II 1/2 D
Application
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
Permanent bullet/pipe magnets are built with a large, cylindrical permanent magnet core, with a powerful, deeply penetrating magnetic field. The magnet core filters the metal particles out of the product flow and retains them on three magnetic poles until they are cleaned.

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?
You have to remove the captured ferrous particles manually. After having stopped the product flow, you can open the door. Then turn the magnet around its own axis, while wiping the magnet clean.
Cleaning / iron discharging sequence
Stop the product flow
Loosen the fastener clamps
Put on sturdy work gloves
Open the door as far as possible
Wipe clean the magnet core while turning it around its axle
Catch the removed ferrous particles and dicharge them
Re-tighten the fastener clamps
Restart the product flow
