Magnetic is permanent magnetism system or electromagnetic system.
Magnetic of the present invention is to be made up of magnetic pole and yoke.Magnetic pole can be a permanent magnet, as strontium ferrite, neodymium iron boron magnetic body, also can be electromagnet.Magnetic pole is fixed by bolts on the yoke base plate, and yoke is with electrical pure iron or silicon steel manufacturing.Magnetic system is fixed in the cylinder, arranges along the cylinder bottom angle of circumference, and the adjacent pole N utmost point, the S utmost point are alternately.
Described cell body can be a downflow type, also can be partly reverse-flow.The spacing of cell body base plate and cylinder surface is 15～80mm.
Described ultrasonic transducer is hyperacoustic emitter, and its effect is to the cell body radiate supersonic wave, produces the ultrasonic cavitation effect in ore pulp, promotes magnetic-particle and gangue depolymerization.
Described supersonic generator produces high frequency electrical signal, and by transmission line input ultrasonic transducer, by electric energy-mechanical energy conversion, producing the high frequency mechanical oscillation is ultrasonic wave.Supersonic generator can onlinely be arranged, also can arrange by off-line.
The present invention installs ultrasonic transducer by magnetic pole gap place and cell body lower surface in magnetic system, to the cell body radiate supersonic wave, utilize cavitation effect of ultrasonic waves, the ore pulp that enters the branch constituency is carried out online dispersion, alleviated effectively that disk pack is wrapped up in, gangue is mingled with phenomenon, improved grade, the yield of concentrate.
