What is a torpedo magnet, pipe-line or bullet magnet?
First of all, all terms refer to the same kind of recycling machine. It's an in-line center-flow magnetic FE-separator that is used in a vacuum or gravity system. The first term means that an airstream blows through the torpedo-shaped machine, where the magnets attract the ferromagnetic components (pneumatic). It can also be placed vertically, so that gravity - and not suction - moves the through the separator. The idea behind the use of gravity is also mentioned on the page regarding the hump magnet.
How does the separation work?
A bullet magnet is basically a steel pipe with a permanent magnet or an electromagnet inside, which is torpedo or bullet shaped. It is positioned right in the middle of the pipe, so there is an empty space surrounding the torpedo magnet. Non ferrous garbage moves past the bullet and Fe clamps to the magnet. On the steel casing of the separator, there is a hinge which can be used to take out and to clean the magnet.Application
A pipe-line magnetic separator isn't made for high volumes of bulky, Fe-contaminated trash. It is much rather meant to distill the last few particles of ferrum from a shredded and pulverised waste stream.Separators like these find their function best in the following sectors:
- Timber industry: it can be perfectly used to extract ferromagnetic parts (example: nails) from a fine waste stream (example: sawdust).
- Plastic recycling: after your plastic has been reduced to a small granulate, it can be fed to the magnetic pipeline separator. As the bullet magnet is quite small, it can easily fit within your plant line.
- Food: fe-contamination in food is a worst case scenario. It's always wise to have magnetic separators and metal detectors everywhere along the line.
- Energy: the ashes of a RDF plant could have ferromagnetic particles. Hence it has to be filtered through a torpedo magnet.
