Description
Technical field
The present invention relates to preparation equipment magnetic-gravity concentrator technical fields, and in particular to a kind of electromagnetic field screening machine.
Background technique
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 use permanent magnetic system, 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 mine particle exists
It sorts and forms slight magnetic coagulation in area, increase the effective gravity of itself, accelerated sedimentation；Magnetic coagulation is when into no field regions
Dispersion；Entering still further below has field regions, and forms slight magnetic coagulation.Gangue and lean intergrowth are raised water flow and take away, and become
Tailing；Magnetic coagulation after purification continues to move downward as concentrate.The equipment exists cannot be by coarse grain intergrowth and biggish arteries and veins
Stone is taken off, easily runs the disadvantages of black.
Column magnetic separator uses electromagnetic field, generates strong and weak changing magnetic field in sorting space, it is poly- to carry out multiple magnetic to ore pulp
Conjunction-dispersion-magnetic polymerization can be sufficiently separated out in conventional magnetic plant product in being mingled with, lean intergrowth and monomer arteries and veins
Stone.The magnetic field of column magnetic separator can be adjusted according to the variation of ore properties.The shortcomings that equipment is that water consumption is big, another is at deficiency
Output qualified tailings are unable to, chats needs to return former process or reprocessed.
Magnetic field screening separator increases magnetic iron ore and gangue and the heavy size of intergrowth using magnetic mine magnetic coagulation in magnetic field
Difference is effectively separated gangue and intergrowth using the sieve being mounted in magnetic field, and chain magnetic coagulation is discharged from sieve becomes essence
Mine, gangue and intergrowth become chats through sieve pore.The equipment is obvious to the selected upgrading effect of magnetic iron ore, and there is granularity to be applicable in model
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 electromagnetic field screening machine.Permanent magnetic field screening machine uses permanent magnetism
Magnetic system, the disadvantage is that magnetic field strength can not be adjusted, screening effect is affected by mine property.
Electromagnetic field screening machine uses two sides electromagnetism magnetic system, which is rectangular solenoid, cannot between two solenoids
More balanced magnetic field is formed, disadvantage is also the magnetic field strength being difficult to by adjusting two sides electromagnetism magnetic system, is formed in sorting area
The sorting magnetic field of suitable magnetic field strength.
Other than deficiency is individually present, their common drawbacks are difficult for magnetic agglomeration gravity separator, column magnetic separator and Magnetic field screening separator
With output qualified tailings, the chats of formation needs to return former process or is reprocessed, and causes process flow complicated in this way, attached
The problems such as piping facility increases, and occupied area increases.In addition, the processing capacity of picking equipment is less than normal, it is difficult to meet industrial production
Need be also a problem.Therefore, it is adjustable to develop magnetic field strength equilibrium, to adaptable to mine change of properties and can be improved
The picking equipment of processing capacity is necessary.
