chute magnetic filters

Standard sizes only 1 week to ship! Special request only 2 weeks to ship!










Chute
magnetic filter (spout magnetic filter) is to use the high-quality
seamless steel tubes and high B value NdFeB rare earth alloy 




and special production methods made of magnet mounted the chute of stainless steel plate in the form of magnetic filters.




When the
iron-containing material by liquid or slurry, attracted by the strong
magnet, the iron-containing material firmly adsorbed on the magnet,




in order to achieve the purpose of removing iron, to ensure product safety.




Permanent chute magnets
have been specially developed for through removal of ferrous metals
from materials in granular and powder from during transport through
pipeline systems.




These
magnet system are built into a housing which is fitted with flat
flanges that, after mounting, they from a single unit with the pipeline
systems.




Guide
strips are fitted on the inside of the housing to ensure that the
material to be purified is well distributed and comes into good contact
with the magnet core.

Permanent spout magnets are used where manual removal of ferrous metals is possible.




The housing of these tube magnets provides access to the magnet core for cleaning by means of hermetically sealing door. 




In the smaller types, the magnet core is fitted to the door, making it easily accessible for cleaning.

How do magnetic bar work?  How are magnetic bar constructed?


Typical construction of a magnetic bar is shown.




Not shown is the 304 stainless steel tube in which this stack of magnets and steel washers (or pole pieces) is inserted.




Most of the grates are made with tubes of non-magnetic stainless steel with an assembly of magnets inside.




The stainless is sealed shut, usually with a weld, which keeps the magnets free from contamination.




The magnets inside the tube are usually arranged in a row, usually with ring magnets sitting on a shaft.











The magnetization direction each successive magnet is assembled in the opposite direction, so that the direction alternates with each magnet.




This specific arrangement is used to create a powerful magnetic field around the assembly.




It produces an extremely high magnetic field right at the steel “pole pieces,” and can exceed 10,000 gauss, even 12000 gauss!




Tiny bits of iron and steel are
attracted to the magnet, with the most force in the locations where the
magnetic field strength changes the most.




Near the pole pieces, this setup can exert a very strong hold onto even fairly small pieces of iron or steel.










Why are they constructed this way?

So many made with this sort of arrangement, its wide use is taken for granted. 


Strong magnetic field as far out as possible from the tube, to catch ferromagnetic particles from as far away as possible. 




This setup uses common, axially magnetized ring magnets to produce a magnetic field in a region around the cylinder.  




It is also strong all the way around the circumference of the cylinder, unlike a diamagnetic magnet, which is strongest at two points (the poles located 180° apart).




The second, it has to do with holding onto the bits of iron or steel to the magnet after they are caught. 




The force exerted on a tiny bit of iron depends on both the field strength and the field strength gradient at given location near the magnet.




The gradient is how much the field strength is changing with distance from the magnet.
