Artificial magnet

Divided horseshoe magnet and hump magnet, is the most common of all life, including the more popular horseshoe magnet. Refers to single-sided magnet magnetic one side, the other side of the magnetic weaker magnet, the method is treated with a special wrap-sided galvanized iron to one side of the magnet, so that one side of the magnetic shield will be wrapped, magnetic is refracted to the other side, the other side of magnetically enhanced. If only one side of the case with a magnetic, if the other side can cause damage or interference magnetic; some occasions, such as a magnet on the box only need one side with a magnetic, the other side is optional, there is no use of magnetic, this will greatly reduce the use of single-sided magnetic magnetic material costs and savings. Sided motor magnet refracted as refracted satellite signals pot or pan flashlight lamp to light refraction, the refraction effect is mainly determined by the following three aspects: 1 material: the choice of materials and thickness, and spacing of the magnet and the material has a close Relationship. Pure iron is easy to MFL, after special treatment refraction will increase, but not 100% shielding material developed, but the effect of different manufacturers make different materials.

Magnet classification

Magnets can be grouped into permanent magnet and magnetic plate， Permanent magnet may be a natural product, known as lodestone, also be made artificially produced (the strongest magnets are neodymium magnets). The non-permanent magnet, and only under certain conditions be magnetic, usually in the form of an electromagnet to produce, i.e. the use of electric current to strengthen the magnetic field. Soft magnetic core including silicon and soft; hard magnetic including aluminum, nickel and cobalt, samarium cobalt, ferrite and NdFeB, of which, the most expensive is samarium cobalt magnet, the cheapest is a ndfeb magnets, NdFeB magnets are the highest performance, but the performance is the most stable, best temperature coefficient is alnico, the user can select different hard magnetic products according to different needs.We are talking about magnets, generally refers to the permanent magnets

Features magnets

  By powder metallurgy production, low residual magnetism, reply small magnetic permeability. Coercivity larger, anti-magnetic ability to strong,magnetic plate separator  especially suitable for use as a dynamic operating conditions of magnetic structure. Hard and brittle materials can be used for diamond cutting tools. The main raw materials are oxides, it is difficult to corrosion. Working temperature: -40 ℃ to + 200 ℃.
Divided into anisotropic ferrite magnets (anisotropic) and isotropic (isotropic). Other magnetic isotropic sintered ferrite permanent magnet materials can weak, but can be magnetized in different directions magnet; anisotropic sintered ferrite permanent magnet material with strong magnetic properties, but only along the magnet predetermined magnetization direction magnetization.

The difference between NdFeB magnet and Ferrite magnets

NdFeB magnets because of their strong magnetism, in many applications the magnet occupies a dominant position, it is the difference between ordinary ferrite magnets is relatively obvious.
      Ferrite magnet is a ferromagnetic metal oxide.magnetic plate separator On the electrical characteristics, the ferrite resistivity than metal, alloy magnetic material is much greater, but also a higher dielectric properties. Magnetic ferrite can also have a higher performance at high frequency permeability. Thus, a wide range of high-frequency ferrite has become weak areas of use of non-metallic material. Belonging to the non-metallic magnetic material is iron oxide and other oxides of one or more metal composite oxide (positive or ferrite). 800-1000 Gauss magnetic force generally, often used in speakers, speakers and other equipment.

Ferrite permanent magnet material

1. Alnico magnet is an alloy of aluminum, nickel, cobalt, iron and other trace metal elements. Casting process can be processed into different sizes and shapes, very good processability. Magentic drawer Cast aluminum nickel and cobalt permanent magnet has a low reversible temperature coefficient, working temperature up to 600 degrees Celsius. Alnico magnet products are widely used in various instruments and other applications.
2. Samarium cobalt (SmCo) on the basis of different components into SmCo5 and Sm2Co17. Because of its materials are expensive and their development is limited. Samarium cobalt (SmCo) as a rare earth permanent magnet, not only has a higher energy product (14-28MGOe), reliable coercive force and excellent temperature characteristics. Compared with NdFeB magnets, SmCo magnet is more suitable for working in high temperature environments.

magnet is more suitable

1. NdFeB magnets which is found in the commercialization of the highest performance magnets, known as magnetic king, have extremely high magnetic its biggest energy product (BHmax) higher than the ferrite (Ferrite) more than 10 times. Machining performance itself is also very good. Operating temperature up to 200 degrees Celsius. And its hard, magnetic grate separator stable performance, good price, so its application is extremely broad. But because of its chemical activity is very strong, it must deal with its surface coating. (E.g. plating Zn, Ni, electrophoresis, passivation, etc.).
2. It is the main raw materials include ferrite magnets BaFe12O19 and SrFe12O19. Manufacturing method made by ceramic technology, texture rather hard, is a brittle material, since the ferrite magnets have good temperature resistance, low cost, moderate performance, has become the most widely used permanent magnets.

MAG magnetic separation reality advantages

Cyclones larger than 1-3 microns is suitable for the purification of non-sticky, non-fibrous dry dust. MAG magnetic grate separator is a simple structure, easy operation, high temperature, equipment costs and resistance (80 to 160 mm of water) purification equipment, purification equipment Cyclones in the most widely applied. Improved cyclone in the portion of the device can replace the exhaust filter device.

the use of MAG magnetic separation

Natural gas purification device into the cyclone zone through the device inlet, MAG magnetic grate separator after the gas containing impurities when axially into the cyclone separator tube, airflow diversion effect by the guide vanes and a strong rotation, airflow along the barrel downward spiral into the cyclone cylinder, high density droplets and dust particles under the centrifugal force thrown towards the wall, and gravity along the tube wall fall out of the mouth of the cyclone dust discharge pipe at the bottom of the reservoir area of ​​the device, from the bottom of the device a liquid outlet flows. Rotating air in the cylinder body contraction flow to the center, up to form a secondary vortex flow through the airway to purge gas chamber, and then flows out through the top of the device outlet.

MAG magnetic separation effect

MAG magnetic grate separator for a respiratory gas sample analyzer includes a closed container having a liquid trap filter chamber integral with the container. The liquid trap filter chamber includes an inlet compartment and an outlet compartment. The inlet compartment is interposed between a sample inlet port and a sample outlet port and includes a gas permeable, liquid impermeable filter element for separating liquid from a gas sample, the liquid separated from the gas sample passing to a collection chamber. The outlet compartment includes a further gas permeable, liquid impermeable trap filter element which is interposed between the collection chamber and a low pressure port, for preventing the flow of liquid through the output compartment to the low pressure port.

MAG magnetic separation production

MAG magnetic grate separator are designed to extract the ferrous material from the liquid, semi-liquid and air conveying powder in order to purify the material in the production process. Strong magnetic tubes inside the housing filtrates the flow and picks out the unwanted ferrous metal. The unit is simply mounted to the existing pipeline via flanged or threaded ends. Easy access is also possible using the quick release clamp.

Magnetic action

After the MAG magnetic grate separator works by other materials to be selected into the sorting space separator, by force and other mechanical forces (such as gravity, centrifugal force, friction, medium resistance, etc.) of the joint action. Suffered by the magnetic force of the magnetic mineral particles the size of magnetic minerals in itself relevant; non-magnetic mineral particles are mainly affected by the action of mechanical forces. Consequent, each movement along different paths, get separation. Generally magnetic particles in a magnetic field and suffered than the size of the magnetic field strength and gradient proportional.
MAG magnetic separation variety, usually in the magnetic field strength, magnetic flux media type, the working medium and the structural characteristics and other classification and nomenclature. The most basic classification is based on the strength of the magnetic field, there are three types: ① weak magnetic separator, the working gap of the magnetic field strength (0.6 ~ 1.6) × 105A / m, used for sorting the strong magnetic minerals; ② the magnetic separator , the working gap of the magnetic field strength (1.6 ~ 4.8) × 105A / m, used for sorting moderate magnetic minerals; ③ strong magnetic field intensity magnetic separator, the working gap of (4.8 ~ 20.8) × 105A / m for election Do weakly magnetic minerals. Since the 1970s superconducting magnetic separator, magnetic field strength up (28 ~ 40) × 105A / m, can sorting weaker magnetic minerals. According to the working medium, magnetic separator has (air) and wet (water) of the points dry. Separator structure and to choose other mineral magnetic strength and size related. In addition to the magnetic pulley used for sorting bulk material, the material can be processed by the particle size is generally a few millimeters to a few microns.

Quality magnetic coatings applied directly to the product's life

Experiments that, 1cm³ NdFeB permanent magnets on the air 150 ℃ of stay 51 days, will all be oxidized etched. In weak acid solution, it is more susceptible to corrosion. To make NdFeB durable, require it to have 20--30 years of life, it must be subjected to a surface anti-corrosion treatment, in order to resist the corrosive medium on the magnet against corrosion. Currently, NdFeB permanent magnet manufacturing industries widely used metal plating, chemical plating + metallization, electrophoretic coating and phosphate processing methods, the magnet surface coated with a layer of additional spacers, the magnet surface and the corrosive medium isolated to prevent violations of media trap magnets . 1, generally zinc, nickel + copper + nickel + copper + nickel electroless nickel plating three technology-based, other metal plating requirements are generally applied in other metal plating after nickel. 2, in some special cases will use phosphate: (1) NdFeB super neodymium magnets products because of turnover, save for too long without a clear follow-up of the surface treatment method when using phosphide simple; ( 2) When the adhesive force of the magnet need epoxy adhesive junction, painting, etc., glue, paint and other organic matter needs epoxy matrix invasion have good performance. Phosphating process can improve the infiltration capacity of the magnet surface. 3, electrophoretic coating has become one of the anti-corrosion surface treatment technology is widely adopted. Not only because of its porous surface of the magnet and the binding force of good, and are resistant to salt spray, acid, alkali and other corrosion, excellent resistance to corrosion. But its heat-resistant properties inferior compared with spray coating. Customers can request for their products work carried plating options. With the expansion of electrical use in the field of corrosion NdFeB customers have higher requirements. The HAST test (also known as PCT test) is a specialized test sintered NdFeB permanent magnets in the humid and high temperature environment of corrosion resistance. And how customers judge coating meets demands? The purpose is to salt spray test surface treated by anti-corrosion coating sintered NdFeB magnets make rapid corrosion test, when the end of the experiment, the samples were removed from the chamber, dried and eyes or a magnifying glass to observe the sample surface without spots , spot size of the area box changes color.

Electromagnetic separator debugging method before running

● Check the coil and electrical insulation properties of the motor, before electricity to meet the requirements after commissioning.

Application of magnetic separators in sorting iron

In order to obtain market recognition and the user's approval, we have increased the property of high magnetic induction in the iron sorting using magnetic separator. So that it has a number of distinctive features user-friendly application. Currently, most of the industrial applications in the area of ​​magnetic separator purification of iron fines in addition to the non-magnetic material, such as abrasives, refractories, chemicals, carbon black, silicon carbide, ceramics and coatings. In addition to iron equipment such structural forms are more common feature is the high magnetic field strength, magnetic field gradients big disadvantage is easy to plug a small processing power, more difficult to clean up the magnetic material, and mostly intermittent work. In recent years, magnetic grate separator has made great progress. Innovative and dynamic magnetic separation process can achieve great success but also that the process can be used in different industrial sectors.
In the iron choose another throughout the process, we strive to simplify the structure of the magnetic separator, so that it can be installed directly in the head of the conveyor belt. Similarly, it can also be configured to separate dry magnetic separation. When the magnetic plate separator, magnetic materials as the belt will move to the top of the drum is adsorbed off automatically go to the bottom, the non-magnetic material in a horizontal parabolic trajectory straight down. After the enhanced magnetic separator to the mine can be operated within 350mm of size, is the breadth of this kind can achieve a rare Several magnetic separator.
