magnetic separator and permanent magnet

magnetic separator and permanent magnet

The magnetic separator uses the magnetic difference between minerals for sorting, plays the role of improving the grade of ore, purifying solid-liquid materials, and recycling waste. It is the most widely used and highly versatile machine in the industry. One.

Magnetic separators are widely used in mining, wood, kiln, chemical, food and other industries. For mining, the magnetic separator is suitable for wet or dry magnetic separation of manganese ore, magnetite, magnetite, roasted ore, ilmenite, hematite and other materials with a particle size below 50mm. , Non-metallic mines, building materials and other iron removal operations and waste disposal operations

The magnetic separator (take wet permanent magnetic cylinder magnetic separator as an example) is mainly composed of 6 parts: cylinder, magnetic roller, brush roller, magnetic system, tank and transmission part. The cylinder is welded into a cylinder by 2-3mm stainless steel plate, and the end cover is cast aluminum or workpiece, which is connected to the cylinder with stainless steel screws. The motor drives the cylinder, magnet roller and brush roller to rotate through a speed reducer or a step-less speed regulating motor.

After the ore slurry flows into the tank through the ore feed box, the ore particles enter the ore feeding area of the tank in a loose state under the action of the water flow of the ore spray pipe. Under the action of the magnetic field, the magnetic ore particles are magnetically aggregated to form a magnetism group or magnetism chain. The magnetism group or magnetism chain is subjected to a magnetic force in the slurry and moves toward the magnetic pole and is adsorbed on the cylinder . Since the polarities of the magnetic poles are alternately arranged along the direction of rotation of the cylinder and are fixed during operation, the magnet or flux rotates with the cylinder, and the magnetic stirring phenomenon occurs due to the alternating magnetic poles and is mixed. The non-magnetic minerals such as gangue in the magnetism or magnetism chain fall off during the tumbling, and the magnetism or magnetism chain that is eventually attracted to the surface of the cylinder is the concentrate. The concentrate is transferred to the weakest part of the magnetic system edge with the cylinder, and it is discharged into the concentrate tank under the action of the flushing water sprayed from the unloading water pipe, and the non-magnetic or weakly magnetic minerals are left in the slurry and discharged out of the tank with the slurry , That is tailings.

Dry magnetic separator: Separation in the air, mainly used to separate large and coarse particles of strong magnetic ore and fine particles of weak magnetic ore. At present, it is also trying to sort fine ferromagnetic ore;

In addition, it can be classified according to the way the magnetic ore particles are selected, the movement direction of the feed material, the method of discharging the selected products from the selected section, and the structural characteristics of the discharged magnetic products.

The closed circuit through which magnetic flux is concentrated is called a magnetic circuit. The magnetic system of the magnetic separator needs to generate a certain intensity of magnetic field, and most of the magnetic flux in the magnetic field can be concentrated through the separation space. The height, width, radius and number of poles of the magnetic system, the magnetic potential difference between adjacent poles, the pole distance, the width of the pole face width and the pole gap width, the shape of the pole and pole face, and the pole face to the center of the arrangement The distance and so on have no small effect on the magnetic field characteristics.

The magnetic separator shown in the following figure is an example. The magnetic circuit part adopts a five-pole magnetic system. Each magnetic pole is formed by bonding a ferrite and a neodymium-iron-boron permanent magnet block. It is fixed to the magnetic guide plate with a screw through the center hole of the magnetic block On the upper side, the magnetic guide plate is fixed on the shaft of the cylinder through the bracket, the magnetic system is fixed, and the cylinder can rotate. The polarities of the magnetic poles are alternately arranged along the circumference, and the polarities are the same along the axial direction. Outside the magnetic system is a roller made of stainless steel non-magnetically conductive material. The non-magnetically conductive material is used to avoid that magnetic lines of force cannot enter the selected zone through the cylinder and form a magnetic short circuit with the cylinder. The part of the tank close to the magnetic system should also be made of non-magnetic materials, and the rest should be ordinary steel plates or hard plastic plates.

For the permanent magnet separator, the permanent magnet is the most important component, and the quality of the permanent magnet determines its performance characteristics. The permanent magnets of magnetic separators are generally made to a certain size (for example, length width height = 85 65 21 mm), so they are traditionally called permanent magnet blocks or magnetic blocks for short. The permanent magnet materials that can be used in the magnetic system of the magnetic separator include permanent magnet ferrite, aluminum nickel cobalt, iron chromium cobalt and manganese aluminum iron, samarium cobalt permanent magnet materials, and neodymium iron boron permanent magnet materials. At present, the mainstream permanent magnetic materials used in domestic magnetic separation equipment are mainly permanent ferrite (strontium ferrite, barium ferrite), followed by neodymium iron boron permanent magnetic materials.

In the design of the magnetic system, it is necessary to choose which permanent magnetic material to use according to the specific conditions of various aspects. The influencing factors can be summarized into the following aspects:

Magnetic field strength: A constant magnetic field must be generated in the designated workspace. The strength of this magnetic field determines which permanent magnetic material is required. The magnetic properties of NdFeB permanent magnets are much higher than ferrites.

Magnetic separation is a process of separating the components of mixtures by the usage of the magnets for attracting magnetic materials. A process which is used for the magnetic separation, detaches the non-magnetic material from those that are magnetic. Such technique is not useful for all, but only for the few minerals like the paramagnetic and ferromagnetic. Not all the metals are magnetic, silver, gold and aluminum are some of the examples.

Large diversity of the mechanical are being used for the separation of the magnetic materials. During the magnetic separation, magnets are present inside the two separator drums that bear drums and due to magnets, the magnetic particles are drifted by movement of drums. This can create magnetic concentrate for example, an ore concentrate.

The magnetic roller separators are most trusted equipment of magnetic separation followed by the industries for separating the ferrous from non-ferrous substances. Magnetic Roller Separator uses the powerful rare earth magnets which perfectly segregate feeds, and this is done by properties and the special series of the magnet used.

Most of magnetic Roller Separators are manufactured in China. For efficient and best quality magnetic roller separators, always consider the Chinese companies. Chinese magnetic roller separators have fixed magnet having the high field intensity and the gradient. Magnets used in magnetic roller separators are made of the alloys of rare-earth elements and these are relatively more powerful than the other magnets. These powerful rare earth magnets generate high attraction forces at the magnetic roller because of their properties and the special magnetic series. Obtained high magnetic forces of attraction have the low magnetic sensitivity and so therefore, separation of the very fine and low magnetic minerals are made possible with a high recovery. The magnets that are used in these rollers are manufactured by the Chinese industries themselves and they are relatively more powerful. Never try to assemble the magnetic roller separator at home, as this is very dangerous. You can get magnetic roller separators from the Chinese companies according to your requirements.

magnetic separator - an overview | sciencedirect topics

magnetic separator - an overview | sciencedirect topics

As magnetic separators progress toward larger capacity, higher efficiency, and lower operating costs, some subeconomic iron ores have been utilized in recent years. For example, magnetite iron ore containing only about 4% Fe (beach sands or ancient beach sands) to 15% Fe (iron ore formations) and oxidized iron ore of only about 10% Fe (previously mine waste) to 20% Fe (oxidized iron ore formations) are reported to be utilized. They are first crushed and the coarse particles pretreated using roll magnetic separators. The magnetic product of roll magnetic separators may reach 2540% Fe and then is fed to mineral processing plants.

As shown in Figure5, slurry is fed from the top of an inclined screen in a low-intensity magnetic field, with the mesh size of screen sufficiently larger than those of particles in slurry. As the slurry flows down the above surface of screen, magnetic particles agglomerate with the size of agglomerations increasingly growing and roll down as magnetic concentrate at the lower end of screen. The less- or nonmagnetic particles pass through the screen as tailings. Figure5 shows the operation of screen magnetic separators for cleaning of magnetite.

Commercial magnetic separators are continuous-process machines, and separation is carried out on a moving stream of particles passing into and through the magnetic field. Close control of the speed of passage of the particles through the field is essential, which typically rules out free fall as a means of feeding. Belts or drums are very often used to transport the feed through the field.

As discussed in Section 13.4.1, flocculation of magnetic particles is a concern in magnetic separators, especially with dry separators processing fine material. If the ore can be fed through the field in a monolayer, this effect is much less serious, but, of course, the capacity of the machine is drastically reduced. Flocculation is often minimized by passing the material through consecutive magnetic fields, which are usually arranged with successive reversals of the polarity. This causes the particles to turn through 180, each reversal tending to free the entrained gangue particles. The main disadvantage of this method is that flux tends to leak from pole to pole, reducing the effective field intensity.

Provision for collection of the magnetic and nonmagnetic fractions must be incorporated into the design of the separator. Rather than allow the magnetics to contact the pole-pieces, which then requires their detachment, most separators are designed so that the magnetics are attracted to the pole-pieces, but come into contact with some form of conveying device, which carries them out of the influence of the field, into a bin or a belt. Nonmagnetic disposal presents no problems; free fall from a conveyor into a bin is often used. Middlings are readily produced by using a more intense field after the removal of the highly magnetic fraction.

Conventional magnetic separators are largely confined to the separation or filtration of relatively large particles of strongly magnetic materials. They employ a single surface for separation or collection of magnetic particles. A variety of transport mechanisms are employed to carry the feed past the magnet and separate the magnetic products. The active separation volume for each of these separators is approximately the product of the area of the magnetised surface and the extent of the magnetic field. In order for the separators to have practical throughputs, the magnetic field must extend several centimetres. Such an extent implies a relatively low magnetic field gradient and weak magnetic forces.

To overcome these disadvantages HGMS has been developed. Matrices of ferromagnetic material are used to produce much stronger but shorter range magnetic forces over large surface areas. When the matrices are placed in a magnetic field, strong magnetic forces are developed adjacent to the filaments of the matrix in approximately inverse proportion to their diameter. Since the extent of the magnetic field is approximately equal to the diameter of the filaments the magnetic fields are relatively short range. However, the magnetic field produced is intense and permits the separation and trapping of very fine, weakly magnetic particles (Oberteuffer, 1979).

The transport medium for HGMS can be either liquid or gaseous. Dry HGMS processing has the advantage of a dry product although classification of the pulverised coal is required to ensure proper separation. Small particles tend to agglomerate and pass through the separator. It has been shown that individual particles of coal in the discharge of a power plant pulveriser flow freely and hence separate well only if the material below about 10 m is removed (Eissenberg et al., 1979). Even then drying of that part of run of mine coal to be treated by HGMS may be required to ensure good flow characteristics.

A schematic representation of a batch HGMS process is shown in Figure 11.5 (Hise, 1979, 1980; Hise et al., 1979). It consists of a solenoid, the core cavity of which is filled with an expanded metal mesh. Crushed coal is fed to the top of the separator. Clean coal passes through while much of the inorganic material is trapped to be released when the solenoid is later deactivated.

Data from a batch HGMS process of one size fraction of one coal are plotted in Figure 11.6 as weight per cent of material trapped in the magnetic matrix, the product sulphur and the product ash versus the independent variable of superficial transport velocity. At low superficial transport velocities the amount of material removed from the coal is high partly due to mechanical entrapment. As the velocity is increased the importance of this factor diminishes but hydrodynamic forces on the particles increase. These hydrodynamic forces oppose the magnetic force and the amount of material removed from the coal decreases (Hise, 1979).

For comparison, Figure 11.7 shows data from a specific gravity separation of the same size fraction of the same coal. While the sulphur contents of the products from the two separation processes are similar the ash content of the HGMS product is considerably higher than that of the specific gravity product. It should be emphasised that this comparison was made for one size fraction of one coal.

More recently dry HGMS has been demonstrated at a scale of 1 t/h on carousel type equipment which processes coal continuously (Figure 11.8; Hise et al., 1981). A metal mesh passes continuously through the magnetised cavity so that the product coal passes through while the trapped inorganics are carried out of the field and released separately.

Wet HGMS is able to treat a much wider range of coal particle sizes than dry HGMS. The efficiency of separation increases with decreasing particle size. However, depending on the end use a considerable quantity of energy may have to be expended in drying the wet, fine coal product. Wet HGMS may find particular application to the precleaning of coal for use in preparing coal water mixtures for subsequent combustion as both pulverising the coal to a fine particle size and transporting the coal in a water slurry are operations common to both processes.

Work at Bruceton, PA, USA has compared the pyrite reduction potential of froth flotation followed by wet HGMS with that of a two stage froth flotation process (Hucko and Miller, 1980). Typical results are shown in Figures 11.9 and 11.10. The reduction in pyritic sulphur is similar in each case although a greater reduction in ash content is achieved by froth flotation followed by HGMS than by two stage froth flotation. However, Hucko (1979) concludes that it is highly unlikely that HGMS would be used for coal preparation independently of other beneficiation processes. As with froth flotation there is considerable variation in the amenability of various coals to magnetic beneficiation.

In the magnetic separator, material is passed through the field of an electromagnet which causes the retention or retardation of the magnetic constituent. It is important that the material should be supplied as a thin sheet in order that all the particles are subjected to a field of the same intensity and so that the free movement of individual particles is not impeded. The two main types of equipment are:

Eliminators, which are used for the removal of small quantities of magnetic material from the charge to a plant. These are frequently employed, for example, for the removal of stray pieces of scrap iron from the feed to crushing equipment. A common type of eliminator is a magnetic pulley incorporated in a belt conveyor so that the non-magnetic material is discharged in the normal manner and the magnetic material adheres to the belt and falls off from the underside.

Concentrators, which are used for the separation of magnetic ores from the accompanying mineral matter. These may operate with dry or wet feeds and an example of the latter is the Mastermag wet drum separator, the principle of operation of which is shown in Figure 1.43. An industrial machine is shown in operation in Figure 1.44. A slurry containing the magnetic component is fed between the rotating magnet drum cover and the casing. The stationary magnet system has several radial poles which attract the magnetic material to the drum face, and the rotating cover carries the magnetic material from one pole to another, at the same time gyrating the magnetic particles, allowing the non-magnetics to fall back into the slurry mainstream. The clean magnetic product is discharged clear of the slurry tailings. Operations can be co- or counter-current and the recovery of magnetic material can be as high as 99.5 per cent.

An example of a concentrator operating on a dry feed is a rotating disc separator. The material is fed continuously in a thin layer beneath a rotating magnetic disc which picks up the magnetic material in the zone of high magnetic intensity. The captured particles are carried by the disc to the discharge chutes where they are released. The nonmagnetic material is then passed to a second magnetic separation zone where secondary separation occurs in the same way, leaving a clean non-magnetic product to emerge from the discharge end of the machine. A Mastermagnet disc separator is shown in Figure 1.45.

The removal of small quantities of finely dispersed ferromagnetic materials from fine minerals, such as china clay, may be effectively carried out in a high gradient magnetic field. The suspension of mineral is passed through a matrix of ferromagnetic wires which is magnetised by the application of an external magnetic field. The removal of the weakly magnetic particles containing iron may considerably improve the brightness of the mineral, and thereby enhance its value as a coating or filler material for paper, or for use in the manufacture of high quality porcelain. In cases where the magnetic susceptibility of the contaminating component is too low, adsorption may first be carried out on to the surface of a material with the necessary magnetic properties. The magnetic field is generated in the gap between the poles of an electromagnet into which a loose matrix of fine stainless steel wire, usually of voidage of about 0.95, is inserted.

The attractive force on a particle is proportional to its magnetic susceptibility and to the product of the field strength and its gradient, and the fine wire matrix is used to minimise the distance between adjacent magnetised surfaces. The attractive forces which bind the particles must be sufficiently strong to ensure that the particles are not removed by the hydrodynamic drag exerted by the flowing suspension. As the deposit of separated particles builds up, the capture rate progressively diminishes and, at the appropriate stage, the particles are released by reducing the magnetic field strength to zero and flushing out with water. Commercial machines usually have two reciprocating canisters, in one of which particles are being collected from a stream of suspension, and in the other released into a waste stream. The dead time during which the canisters are being exchanged may be as short as 10 s.

Magnetic fields of very high intensity may be obtained by the use of superconducting magnets which operate most effectively at the temperature of liquid helium, and conservation of both gas and cold is therefore of paramount importance. The reciprocating canister system employed in the china clay industry is described by Svarovsky(30) and involves the use a single superconducting magnet and two canisters. At any time one is in the magnetic field while the other is withdrawn for cleaning. The whole system needs delicate magnetic balancing so that the two canisters can be moved without the use of very large forces and, for this to be the case, the amount of iron in the magnetic field must be maintained at a constant value throughout the transfer process. The superconducting magnet then remains at high field strength, thereby reducing the demand for liquid helium.

Micro-organisms can play an important role in the removal of certain heavy metal ions from effluent solutions. In the case of uranyl ions which are paramagnetic, the cells which have adsorbed the ions may be concentrated using a high gradient magnetic separation process. If the ions themselves are not magnetic, it may be possible to precipitate a magnetic deposit on the surfaces of the cells. Some micro-organisms incorporate a magnetic component in their cellular structure and are capable of taking up non-magnetic pollutants and are then themselves recoverable in a magnetic field. Such organisms are referred to a being magnetotactic.

where mpap is the inertial force and ap the acceleration of the particle. Fi are all the forces that may be present in a magnetic separator, such as the magnetic force, force of gravity, hydrodynamic drag, centrifugal force, the friction force, surface forces, magnetic dipolar forces, and electrostatic forces among the particles, and others.

Workable models of particle motion in a magnetic separator and material separation must be developed separately for individual types of magnetic separators. The situation is complicated by the fact that many branches of magnetic separation, such as separation by suspended magnets, magnetic pulleys, or wet low-intensity drum magnetic separators still constitute highly empirical technology. Hesitant steps have been taken to develop theoretical models of dry separation in roll and drum magnetic separators. Alternatively, open-gradient magnetic separation, magnetic flocculation of weakly magnetic particles, and wet high-gradient magnetic separation (HGMS) have received considerable theoretical attention. A notable number of papers dealing with the problem of particle capture in HGMS led to an understanding of the interaction between a particle and a matrix element. However, completely general treatment of the magnetostatic and hydrodynamic behavior of an assembly of the material particles in a system of matrix elements, in the presence of a strong magnetic field, is a theoretical problem of considerable complexity which has not been completed, yet. Detailed description of particle behavior in various magnetic separators can be found in monographs by Gerber and Birss (1983) and Svoboda (1987, 2004).

The brick material ratio was: Slag(1.0mm<): Grog (3.0mm<): Ceramic Gravel (1.0mm<): Clay (1.0mm<) at 20 : 35 : 25 : 20. To this mixture, 2% of pigment were added. Kneading and blending was done by a Mller mixer for 15 minutes. Molding was done by a 200 ton friction press, and the bricks were loaded onto the sintering truck.

This paper presents preliminary results using the Magnetic Micro-Particle Separator, (MM-PS, patent pending) which was conceived for high throughput isothermal and isobaric separation of nanometer (nm) sized iron catalyst particles from Fischer-Tropsch wax at 260 oC. Using magnetic fields up to 2,000 gauss, F-T wax with 0.30.5 wt% solids was produced from 25 wt% solids F-T slurries at product rates up to 230 kg/min/m2. The upper limit to the filtration rate is unknown at this time. The test flow sheet is given and preliminary results of a scale-up of 50:1 are presented.

Most loads for flap valves, conveyors, vibrating feeders, crushers, paddle feeders, magnetic separators, fans and trash screens generally are supplied at 415 V three-phase 50 Hz from the 415 V Coal Plant Switchboard, although 3.3 kV supplies may be used when the duty demands. Stacker/reclaimer machines are supplied at 3.3 kV. Electrical distribution is designed to safeguard the independent operational requirements of the duplicated coal plant facilities and to ensure that an electrical fault will not result in the total loss of coal supplies to the boilers.

The first step in any form of scrubbing unit is to break the lumpy materials and remove tramp elements by a magnetic separator. The product is then led into the scrubbing unit. The dry scrubbing principle is to agitate the sand grains in a stream of air so that the particles shot-blast each other. A complete dry scrubbing plant has been described in a previous book of this library in connection with sodium silicate bonded sands.* For clay-bonded sands the total AFS clay content in the reclaimed sand varies from 05% to 25% clay depending on the design of the plant.
