Description
Technical field
The present invention relates to preparation equipment magnetic-gravity concentrator technical field, and in particular to a kind of concentrate type multistage electromagnetism magnetic field sieve
Select machine.
Background technology
It is the selected important method of magnetic iron ore that magnetic reconnection, which closes beneficiation method, mainly has magnetic group using the equipment of this method development
Poly- gravity concentrator, column magnetic separator and Magnetic field screening separator.
Magnetic agglomeration gravity separator uses permanent magnetic system, and magnetic system is cylindrical, be divided into, in, outer three layers of magnetic system, interior magnetic system with
Two sorting areas between middle magnetic system, middle magnetic system and outer magnetic system form uneven discontinuous stationary magnetic field.Magnetic ore deposit particle exists
Sort and slight magnetic coagulation is formed in area, add the effective gravity of itself, Accelerated subsidence；Magnetic coagulation is when entering without field regions
It is scattered；Entering still further below has field regions, forms slight magnetic coagulation again.Gangue and lean intergrowth are raised current and taken away, and turn into
Mine tailing；Magnetic coagulation after purification continues to move downward as concentrate.The equipment is present can not be by coarse grain intergrowth and larger arteries and veins
Stone is taken off, easily runs the shortcomings of black.
Column magnetic separator uses electromagnetic field, and the magnetic field of strong and weak change is produced in sorting space, and carrying out multiple magnetic to ore pulp gathers
- scattered-magnetic polymerization is closed, can be sufficiently separated out in being mingled with conventional magnetic plant product, lean intergrowth and monomer arteries and veins
Stone.The magnetic field of column magnetic separator can be adjusted according to the change of ore properties.The shortcomings that equipment is that water consumption is big.
Magnetic field screening separator utilizes magnetic ore deposit magnetic coagulation in magnetic field, increases magnetic iron ore and gangue and the heavy size of intergrowth
Difference, effectively gangue and intergrowth are separated using the screen cloth in magnetic field, chain magnetic coagulation is discharged from sieve as essence
Ore deposit, gangue and intergrowth turn into chats through sieve aperture.The equipment there is granularity to be applicable model the selected upgrading positive effect of magnetic iron ore
Enclose the advantages that wide, water consumption is small, and sharpness of separation is high.
Magnetic field screening separator is divided into permanent magnetic field screening machine and electromagnetism Magnetic field screening separator.Permanent magnetic field screening machine uses permanent magnetism
