Abstract

The invention relates to magnetic enrichment and makes it possible to increase the efficiency of the separation process by reducing the residual magnetization of the magnetic core and ferromagnetic bodies. The device includes a cassette 1 with magnetized balls (NS) 2 placed in it, an electromagnetic system consisting of a solenoidal winding 3, a magnetic circuit 4 with an upper pole (P) 5 and a lower P 6 located above and below the cassette 1, loading and discharge pipe. At that, P 5 is installed with the possibility of reciprocating vertical motion by means of mechanism 10 and is made in the form of a truncated cone 9. The angle of inclination of the generatrix of cone 9 to the horizontal is PO-120 ° C. The original pulp is fed to the cassette 1, and the passage through the NSh 2 layer is divided into fractions. The non-magnetic fraction is removed with water through the channels P 6 and the discharge port. Then the magnetic field is turned off, and П 5 is lifted by the mechanism 10, and the magnetic circuit is broken. The NSH 2 is cleaned of adhering magnetic particles and is discharged through the discharge nozzle. 1 hp f-ly, 2 ill. I (L
