The outer end of the groove with a bolt fixed on the stent, the inner end close to the branched thrust disc cantilevered portions. Special clever design of the blade, respectively, located in the inductor between the bottom of both sides, cross-section into a v - shaped, steel back and abrasion rubber plate, the upper end of the sleeve on the spindle, to facilitate the after-sale wear quickly, easily around the shaft revolutions out to replace the rubber plate with Alice legislation annular retaining plate. Two sets of rolling bearings and motors features are as follows: (1) by means of adsorption of water and gravity of the magnetic material, to realize a non-water discharge (discharge concentration of more than 50% of the unloaded net rate of more than 98%), discharge to net zero-cycle load, water-saving The effect is remarkable, and more suitable for dryland. (2) the magnetic magnetic system, magnetic ring optionally, the gap Bare strength and the role of the magnetic induction gradient along the axial direction toward the work surface magnetic induction 0.15,0.3 T ring intermediate magnetic induction intensity OI to Page. T High recovery efficiency, magnetic iron recovery rate as high as 90% to 95%, the basic realization of a real recovery time net. (3) the same amount of processing, the cost of minimum cost is 20% of the large diameter tube magnetic separator price, disc type permanent recycling machine price is 50%, 90% the JHC type moments ring permanent recycling machine.
