Step 6: disk adjustment module comprises the motor being connected to worm and wormwheel reductor, for receiving executive signal 201, will respond to the rotational speed regulation of disk (4) to predetermined value 11; Receive executive signal 202, the rotational speed regulation of disk (4) will be responded to predetermined value 12; Receive executive signal 203, the rotational speed regulation of disk (4) will be responded to predetermined value 13; Receive executive signal 601, distance adjustment will to be responded between disk (4) and electromagnet (5) within the scope of 0-20mm; Receive executive signal 204, and the rotating speed responding to disk (4) lowers N1* predetermined value 14; Receive executive signal 205, and the rotating speed responding to disk (4) raises N2* predetermined value 14;
Step 7: current regulating module, receives executive signal 301, by the supply Current adjustment of electromagnet group to predetermined value 21; Receive executive signal 302, by the supply Current adjustment of electromagnet group to predetermined value 22; Receive executive signal 303, by the supply Current adjustment of electromagnet group to predetermined value 23; Receive executive signal 304, and the induced current that supplies of electromagnet group is lowered N1* predetermined value 15; Receive executive signal 305, and the induced current that supplies of electromagnet group is raised N2* predetermined value 15;
Step 8: roll adjustment module comprises the mobile adjusting device being located at each electromagnet group, receives executive signal 501, the distance values of electromagnet group is turned down, until L
distance< responds to the diameter of disk (4);
Alarm module comprises siren, receives executive signal 401 or executive signal 402, starts siren, sends prompt tone;
Step 9: non-magnetic product transports to mine tailing end by belt, enters in the trough of non-magnetic product.
