In addition to economic iron not only to economic procurement of iron removal equipment more to the correct use of electromagnetic iron removal device, the following for you to introduce the economic use of iron removal equipment several measures:
(1) In the same production line can be used to mix the use of permanent magnet electromagnetic, the first use of cheap magnetic field weak permanent magnet iron removal, remove strong magnetic iron impurities, after the purchase price and use cost are higher, but the magnetic field of high power electromagnetic iron removal.
(2) In the selection of permanent magnet in addition to the diameter of the iron bar, should not be selected too large. Since increasing the surface area of contact between the magnetic source and iron impurities can increase the chance of catching prey, although increasing the direct longitude can increase the surface area of a rod, but under the premise of the same weight of the permanent magnet source material, reducing the direct longitude of the magnetic rod can increase the number of rods, which can greatly increase the surface area. When the cross section of the large flow slurry is high, the multilayer magnetic bar can be used for the treatment.
(3) The old magnetic rod magnetizing renovation, as long as the magnetic rod sleeve is not rotten, the magnetic core is not oxidized metamorphic, renovation can reach the original level of use the same effect, the investment can be saved about 49%.
