Description

Magnetic field beneficiation method and preparation equipment thereof
Technical field
The invention belongs to ore dressing field, be specifically related to a kind of magnetic mineral screening installation and method.
Background technology
Magnetic separation is a kind of method of simple and effective separation Magnetic Materials and nonmagnetics.Non-uniform magnetic-field screening installation, as various magnetic separators, although can carry out sorting for different types of ore deposit, is easily mingled with namagnetic substance in its magnetisable material sorting out.
All to carry out sorting in approximate uniform magnetic field environment according to the magnetic agglomeration gravity separator of magnetic coagulation principle invention and column magnetic separator.Its principle is that the method for utilizing back-flushing to carry out fluidized classifying separates the Magnetic Materials of reuniting with the nonmagnetics of not reuniting.Be mingled with for reducing, these two kinds of equipment are all discontinuous by magnetic system design, make it to realize the effect of reunite-dispersion-reunion, and in the time disperseing, flushing water can separate nonmagnetics.Although these two kinds of equipment can effectively reduce and be mingled with, very easily under the effect of back-flushing, lose for particulate Magnetic Materials, equipment needs a large amount of water to recoil in running simultaneously, is unfavorable for reducing discharging.
Magnetic field screening separator is to utilize the magnetic plant that carries out sorting in the approximate uniform magnetic field environment of another kind of Magnetic field screening method principle invention.Its principle is to utilize symmetrical pair of planar magnetic system of placing to form uniform magnetic field, and Magnetic Materials magnetizes and forms chain form in magnetic field, utilizes the method for screening that the Magnetic Materials of forming chain form is separated with loose nonmagnetics.The method and equipment efficiently solve magnetic agglomeration gravity separator and column magnetic separator water loss is large and particulate Magnetic Materials reclaims the weak deficiency of ability.But this Magnetic field screening separator has part nonmagnetics can not separate in the middle of being mixed in magnetic linkage while use, Magnetic field screening separator magnetic is permanent magnetic system simultaneously, and field intensity is difficult for regulating, and can not meet multiple demand.
Summary of the invention
The object of the invention is, for above-mentioned the deficiencies in the prior art, provides a kind of magnetic field beneficiation method and preparation equipment thereof, realizes Magnetic Materials and effectively separates with nonmagnetics, in avoiding being mingled with nonmagnetics in Magnetic Materials, has the higher Magnetic Materials rate of recovery.
Technical scheme of the present invention realizes in the following manner: a kind of mineral selecting equipment by using magnetic field, comprise rotation screen drum, rotation screen drum two ends are provided with screen cover and lower screen cover, upper screen cover is connected with motor, rotation screen drum top is provided with screen cloth, be provided with mine tailing discharge pipe and concentrate discharge pipe with the housing sidewall of the concentric installation of rotation screen drum, in the middle of mine tailing discharge pipe and concentrate discharge pipe, separate with dividing plate, housing two ends are provided with upper cover and lower cover, upper cover, upper screen cover is installed with feed pipe is concentric, lower cover and lower screen cover are installed with one heart, housing top is wound with coil, coil input end is connected to the unidirectional current of pulsatile change.
Described jet water spout is connected with concentrate discharge pipe.
What described coil was inputted is the unidirectional current that has pulsatile change
The present invention is arranging coil outward with the housing of the concentric installation of rotation screen drum, and on coil, input has the unidirectional current of pulsatile change, and when operation, device interior is full of water.Pre-separation material enters rotation screen drum through feed pipe, under the effect in the magnetic field producing at coil, magnetic mineral is magnetized and forms with magnetic linkage in the same way of the magnetic line of force and fall on the compass screen surface of rotation screen drum, under the sieving actoion of rotation screen drum, namagnetic substance separates with Magnetic Materials through screen cloth, and the magnetic linkage particle diameter that Magnetic Materials is formed is greater than mesh size, the material above screen cloth moves ahead along compass screen surface under deadweight.The magnitude of field intensity pulsatile change one direction that has the unidirectional current of pulsatile change that coil is produced is constant, thereby reaches the loose process of the magnetic chain of formation.Be divided into two products through repeatedly reunite-loose-reunion with after constantly sieving, arrive respectively concentrate discharge pipe and mine tailing discharge pipe.In addition, in concentrate discharge pipe, be added with back-flushing, thereby carry out fluidization sorting in concentrate discharge pipe time, further improve separating effect.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, the present invention includes rotation screen drum 7, rotation screen drum 7 two ends are provided with screen cover 6 and lower screen cover 11, upper screen cover 6 is connected with motor, rotation screen drum 7 tops are provided with screen cloth, be provided with mine tailing discharge pipe 8 and concentrate discharge pipe 10 with housing 12 sidewalls of the concentric installation of rotation screen drum 7, in the middle of mine tailing discharge pipe 8 and concentrate discharge pipe 10, separate with dividing plate, housing two ends are provided with upper cover 4 and lower cover 1, upper cover 4, upper screen cover 6 and the concentric installation of feed pipe 5, lower cover 1 and lower screen cover 11 are installed with one heart, and housing 12 tops are wound with coil 3.
The electric current passing through on described coil 3 is the unidirectional current that has pulsatile change, such as sinusoidal current.
In the present invention, sense of current is constant all the time, can prevent the magnetic chain fracture that magnetisable material produces, in addition, size of current, in continuous change, can make the magnetic size variation of magnetisable material, like this, the namagnetic substance being mingled with in magnetisable material is easy to come off.
The course of work of the present invention is as follows, feed pipe 5 arrives pre-separation mass transport in rotary barrel 7, the upper screen cover 6 of rotary barrel 7 is equivalent to power transmission shaft simultaneously, be connected with motor, driven rotary cylindrical shell 7 rotates, under the magnetic fields producing at coil 3, magnetisable material separates with namagnetic substance, magnetisable material is reunited and is chain form, magnetisable material and nonmagnetics are along with device inclined direction is advanced afterwards, when through screen cloth time, namagnetic substance diameter is little, can leak the online mesh that sieves, flow out by mine tailing discharge pipe 8, and the magnetic linkage particle that Magnetic Materials is formed is larger, can not be by the mesh on screen cloth, continue along with device inclined direction is advanced, finally get rid of by concentrate discharge pipe 10, realize separating of Magnetic Materials and nonmagnetics.
Equipment overflow water is discharged by the hollow shaft of lower screen cover 6, and the height of set outlet can regulate the height of liquid level in screening installation.
Whole device inclined is installed, inclination angle is adjustable, and rotation screen drum is adjustable by driven by motor rotating speed, and excitation power supply size of current and pulsation rule are all adjustable.The present invention has the advantages such as water saving, adjustable, high throughput simultaneously.
