Under the action of the negative pressure for setting I (11-1) generation, miberal powder is fed from feed port (1), miberal powder, which enters, gives mine negative-pressure air duct (2-1),
And enter 2 or more magnetic separating units by dispersal device (3) and carry out sorting work, miberal powder is fully dispersed under dispersal device effect
Enter in magnetic separating unit afterwards, magnetisable material is adsorbed on magnetic medium body (8) under the magnetic fields that electromagnetic coil (7) generates, non-
Magnetic mineral enters non-magnetic product collection device (10-1) by non-magnetic product negative-pressure air duct (2-3) under the action of negative pressure
In；
After magnetic separating unit sorts 1~99min, the magnetic separating unit of closing quantity half gives mine valve (4) and valve II (5),
And the valve I (6) and air inlet (12) of magnetic separating unit are opened, electromagnetic coil (7) power-off of magnetic separating unit, the magnetic of magnetic separating unit is situated between
The magnetisable material adsorbed on plastid is entered under negative pressure ventilation device II (11-2) effect by magnetic product negative-pressure air duct (2-2)
To in magnetic product collection device (10-2)；The other half magnetic separating unit of quantity still carries out separation operation；
After 1~99min of magnetic separating unit ore discharge of quantity half, the mine valve (4) and valve II of these magnetic separating units are opened
(5), the valve I (6) and air inlet (12) of magnetic separating unit are closed, the electromagnetic coil (7) of magnetic separating unit is powered, this part magnetic separation list
Member carries out separation operation again；Simultaneously close off quantity the other half magnetic separating unit to mine valve and valve II, and open magnetic separation
The valve I and air inlet of unit, the electromagnetic coil power-off of magnetic separating unit, this another part magnetic separating unit start to carry out ore discharge work
Industry so works alternatively, and realizes that continuous dry-type is made except ironworker.
8. application method according to claim 7, it is characterised in that: electromagnetic coil (7) generates 100 under the function of current
The magnetic field of~16000GS.
9. application method according to claim 7, it is characterised in that: giving wind speed in mine negative-pressure air duct is 0.1~100m/s,
The strip concentration of wind is 0.1~500kg/m3。
