Magnetic Tube

Food and Pharmaceutical Processing

Magnetic tube, also named a magnetic bar, magnetic rod, magnetic roll separator, is constructed with neodymium permanent magnets which require no extra energy. They can remove iron contaminants to purify the material and protect the equipment. The strong neodymium bar magnets is TIG welded, sealed, and waterproof. After 4 polishing procedures, the surface roughness reaches RA0.6 which fully meets the requirements of food and pharmaceutical production. Unlike a simple magnet, a magnetic tube consists of multiple magnets that form a magnetic circuit, improving the strength of the magnetic field by twice as much as a single magnet, thus meaning that a magnetic tube is better at absorbing fine particles. Leyuan, as one of the magnetic bar manufacturers, offers heavy-duty permanent magnet bars of different shapes, including round bar magnet, a rectangular bar magnet, long rod magnets, and large bar magnets.


As one of the most professional magnetic bar suppliers from China, Leyuan has strong bar magnets for sale. If you want to buy a bar magnet or want to know our other product information such as grid magnet, magnetic grate separators, a powerful bar magnet, permanent magnet bar, rare earth rod magnets, liquid line magnetic separator, and heavy-duty bar magnets, please contact Leyuan or leave a message through our website.

4. Magnetic Tube's Length

Custom and made to any length


5. Surface Gauss Value

Finite element models can calculate the strength of a magnetic field. It is quite difficult, but practical we use the value below:

Dry Powder:8000 Gauss

Wet Slurry:10000 Gauss

Nanometer Particles:over 12000 Gauss


6. Endplugs Installation of Magnetic Roll Separators

Various end plugs based on your requirements, the most common are the following:

Taped Holes


Threaded Studs


Plain Ends


The Advantages of Magnetic Tube

1. Polishing Meet Food or Pharmaceutical Processing

After 4 polishing procedures, the surface roughness reaches RA0.6.

Polishing meet food or pharmaceutical processing


2. Installation Verticality

When the magnetic bar is fixed vertically to the flat plate, the end face of the magnetic bar must be closely attached to the flat plate. We have one more process than other suppliers, which can eliminate this deviation.
