Description
Technical field
This utility model belongs to iron mineral upgrading technical field, is specifically related to a kind of electromagnetism Magnetic field screening separator.This equipment can
Selected for mineral such as magnetic iron ore, vanadium titano-magnetite and roasting magnetic iron ores.
Background technology
At present, China's iron ore deposit lean, thin, hydridization trend is increasingly severe, how to improve iron concentrate grade, reduce energy
Consumption, the emphasis direction of cost-effective Cheng Shi China iron ore beneficiation research.Magnetic agglomeration gravity separation method is the important method that magnetic iron ore is selected,
The equipment utilizing the method to develop mainly has magnetic agglomeration gravity separator, column magnetic separator and Magnetic field screening separator.
Magnetic agglomeration gravity separator uses permanent magnetic system, and its magnetic system cylindrically, has 3 ~ 4 layers, is divided into interior magnetic system, middle magnetic system, outer
Magnetic system, every layer of magnetic piece is interrupted configuration, and two sorting districts between interior magnetic system and middle magnetic system, middle magnetic system and outer magnetic system form 0 ~
The low uneven discontinuous stationary magnetic field of 15mT, sorting current feed sorting district with certain pressure to water ring.Magnetic iron ore
Granule, under the synergy of magnetic field force, ascending current power and self effective gravity of change, is formed when entering sorting district
Slight magnetic coagulation；Magnetic coagulation is disperseed owing to ascending current applies to shear flushing action to ore pulp when entering without field regions；
Enter still further below and have field regions, owing to the effect of magnetic field force forms again slight magnetic coagulation.Magnetic coagulation is in infall process
The scattered state of dispersion reunion repeatedly, is continuously available purification washing away of current of sorting, presss from both sides in magnetic coagulation under elutriation effect
Miscellaneous monomer stone-like pulse and intergrowth are raised current and take away, and become mine tailing；Magnetic coagulation after purification continues to move downward becomes essence
Ore deposit.The shortcoming of this equipment be coarse grain intergrowth and stone-like pulse can not be taken off, easily run black etc..
Column magnetic separator uses special power supply mechanism to make magnet exciting coil produce special magnetic field transformation mechanism in sorting space, right
Ore pulp carries out repeated multiple times magnetic polymerization dispersion magnetic polymerization, can be sufficiently separated out in conventional magnetic plant product and be mingled with
In, lean intergrowth and monomer stone-like pulse.The magnetic induction of column magnetic separator, and can be according to ore properties between 0 ~ 20mT
Change regulates at any time, and the magnetic field in choosing point space cuts in and out, order is the most downward, move in circles, and cycle period is also dependent on ore deposit
The change of stone character regulates at any time.Its Separation process: entered column magnetic separator middle and upper part, magnetic by mine feeding bucket through mineral-feeding pipe to ore deposit ore pulp
Granule particularly monomer magnetic-particle, under magnetic field force effect from top to bottom, is reunited and dispersion is alternately and repeatedly carried out, add
The flushing of tangential ascending current from bottom to top, elutriation effect, make to be entrained in monomer stone-like pulse therein and in, lean intergrowth is by upper
Rise current and drive rising, upper isopipe overflowing becomes mine tailing.Magnetite ore particles, including monomer magnetite ore particles and magnetic iron ore
Rich intergrowth, under the effect of the most downward magnetic field force and magnetic linkage effective gravity, is not rushed band by ascending current, and by bottom
Concentrate ore discharge bank of tubes goes out to become high-grade magnetite concentrate.The shortcoming of this equipment is that water consumption is big, and energy consumption is high, and device height is relatively
High.
Magnetic field screening separator is the Novel magnetite beneficiation that Zhengzhou Institute of Multipurpose Utilization of Mineral Resources, CAGS develops
Patent equipment.Magnetic sieve is easily mingled with stone-like pulse mainly for tradition magnetic separator, is more difficult to separate the defect of intergrowth, utilizes magnetic iron ore
In relatively uniform low-intensity magnetic field, magnetic iron ore is magnetized into chain magnetic agglomerate, increases magnetic iron ore and stone-like pulse intergrowth sedimentation velocity
Difference, difference in size, utilize the screen cloth being arranged in magnetic field effectively to be separated with intergrowth by stone-like pulse, and chain magnetic agglomerate is discharged from sieve
Become concentrate, stone-like pulse and intergrowth and become chats through sieve aperture.This equipment upgrading selected to magnetic iron ore effect is obvious, has granularity
Applied widely, water consumption is little, sharpness of separation is high and low power consumption and other advantages, and shortcoming is to use permanent magnetic system, magnetic field intensity without
Method regulates, and concentrate grade is by being affected bigger to ore deposit character.
In sum, this kind of low low-intensity magnetic field picking equipment with Magnetic field screening separator as representative solves to perplex China's iron mine substantially
Miscellaneous problem drops in upgrading for many years, but also has energy-saving and cost-reducing effect to a certain extent, but there is also respective shortcoming.
