Magnetic separator is the most widely used in the industry, the high versatility of the aircraft, one for recycling the removed powder particle body such as iron. In recent years the development of magnetic separator is quite fast, however, although the rapid development of magnetic separation equipment, but still can not keep up with the iron on the market, and now there are dozens of kinds separator classification, and its excellent performance has been recognized by the majority of users. According to the survey, magnetic separator equipment sales in the rate of 30% per day increased significantly, the use of equipment obtained lucrative, so many companies also have to enter this industry, many companies are prior to expanding the industry scale, the overall use of magnetic separators in the rise. overband magnet
Magnetic separator equipment trends, magnetic application equipment industry is smaller, more dispersed distribution companies, many enterprise data, especially SMEs, the data is difficult to get, I will be the industry representative enterprise data as a proxy variable to reflect the industry The overall operating conditions, and will be used in the analysis process correlation analysis.
According to market forecasts, China's magnetic separator in 2008 when the market is about more than 1.1 billion, in 2009, when magnetic separator equipment industry of China's coal mining and washing total construction grew by 53.1%, increase in Net Size 84.4%, showing a strong momentum of growth. Accelerated investment in fixed assets under the pull of China's coal mining and washing industry investment in fixed assets grew by 27.4%, including equipment purchase tools plus 24.4% positive. Magnetic separator as coal mining and washing of the necessary equipment, one can obtain a faster growth rate. magnetic drums
Magnetic separation is an integral part of selected mineral separation, and performance quality magnetic separator magnetic separation process is a key factor. Introduced in recent years, the structure and magnetic separation equipment domestic production live, elaborated magnetic separator actual status and trends. Accompanied by a magnetic separator technology constantly updated and growing development of permanent magnetic separator technology and began to develop in the direction of large-scale, as well as solve the low-grade, fine granularity, weakly magnetic minerals sorting opened a new road .
Currently, the more popular Chinese and foreign enterprises jointly set up factories, is to "market for technology." Despite the recent years, domestic companies are trying to seek a breakthrough in magnetic separation technology, but there is still a big gap with foreign countries. But the gap is not narrowing paragraph, I believe there is hope in the next few years to catch up with and surpass the advanced level.

optional separator four fatal errors

Magnetic separator as beneficiation equipment industry's most widely used, general-purpose high performance products. Here we explain just buy magnetic separator beneficiation equipment in the process, what errors need to note:
1, the magnetic device from a link, in addition to iron equipment handling a system of magnetic material pollution problems. Magnetic inevitable according to regulations of the device. magnetic knife holder
2, does not distinguish between the situation of the material in the magnetic material, the blind pursuit of higher magnetic field, too. The magnetic character of the material conditions which resolution you should use magnetic separation equipment, magnetic separation equipment which is more suitable for your kind of magnetic material tasks more efficient. The higher the magnetic field is not the task of the efficiency and the yield will be higher.
3, a single dry magnetic separation process a variety of materials in the magnetic material. General conditions one kind of magnetic separator magnetic separator settings are concentrated along a local material characteristics of these materials contain certain magnetism that these are the elements that this element separator separator can be difficult to come out and other magnetic elements elected. magnetic separation
4, blind investment, the investment is tantamount to deal with the problem. We should note that this is necessarily thinking investment effectiveness, we want our customers with an excess of investment to bring more benefits.

Mining Machinery separator where the vitality in the end

China is a country rich in mineral resources, with the world's industrial and technological progress, human beings for the growing demand for mineral resources, which the mining companies had a lot of pressure, exploitation of minerals in short supply. How to efficiently mine the resources will be effectively screened out as the current topic. Henan Rueiguang professional mineral processing equipment manufacturer to you by a magnetic separator to show modern dressing prospects. Magnetic Head Pulley
Iron ore is currently the most used, the greatest demand for minerals. When iron ore sorting equipment is the most commonly used magnetic separator, it is today's form of dressing. Magnetic Separator has been thinking about intelligent, large-scale development. Magnetic Separator in nearly 40 years of development, gradually formed its own unique pattern. After years of production separator beneficiation model has matured, all major equipment manufacturers constantly improve intelligence production process.
Beneficiation process localization trend. With the domestic research level, beneficiation equipment of recent patent applications significantly more emphasis on the support of their research results. Well, this will also inspire scientists too large for our processing equipment to catch up with the world advanced level intended contribution. Eighth, the trend of manufacturing orders. In the past, device model, performance and more fixed, companies tend to have certain levels. At this stage due to customer demand for increasingly sophisticated specific compounds, a direct result of manufacturing enterprises in the pursuit of zero inventory theories have nominal efforts. Neodymium Arc Magnets

Energy saving is the future of magnetic separation equipment industry will inevitably move toward a big trend.

Separator technology continues to progress in the development of today's society

Magnetic materials handling technology is one of the foundations, the past 30 years, magnetic separation has made great progress. The advantage of magnetic material is its wide range of applications. Magnetic separation process innovation power and can achieve great success also lies in the process can be used in different industrial sectors. This paper will present situation and future development of magnetic direction of development is reviewed.
Generating the magnetic field and the magnetic field gradient
Although the permanent magnet used for decades to generate a magnetic field in the magnetic separator, however, until cheap to produce high energy product and high coercive force of the ferrite magnet appeared before they get further permanent magnet application. Recently, the development of a strong rare earth permanent magnet materials, a new generation of permanent magnet roller drum magnetic separator appears. In such a roll is generated on the surface of the magnetic induction up to 1.9T and a high magnetic field gradient strength. Early, with the electromagnet core generates a magnetic field in the magnetic separator. Although this magnet still plays an important role, but, as the permanent magnets and the resistor of the air core coils and superconducting rotating air core coils spin occurs it has lower importance. The main disadvantage of the magnet core, which can be achieved by a magnetic field strength of the magnetic induction saturation magnetization of iron restriction. And, this magnet is restricted enlarged scale. Even moderate working gap, the magnet makes the amplification reduces the magnetic induction field, increase the weight of the separator. This magnet produces a magnetic flux density of not more than 1T.
On the contrary, there is resistance in the larger spiral magnet workspace produce up to 2T magnetic induction. This allows the manufacture of large magnet strong magnetic separator, its processing capacity can reach 100t / h. Superconducting magnet magnetic induction intensity can increase to 5T or higher, though, the most frequently applied magnetic separator magnetic induction is generally not more than 2T. pot magnets
There are two ways to generate the magnetic field gradient method, as seen from formula (1) is seen, the magnetic field gradient is also very important. By proper arrangement of permanent magnet blocks, or the magnet properly sharpened, or is reasonably arranged magnet poles, the magnetic induction intensity of the magnetic field may change and generating a magnetic field from the magnets as a function of the distance. This is called open gradient magnetic field gradient, in most drum magnetic separator, magnetic separator roller and plate separator machine is the application of the magnetic field gradient. In the hanging magnet magnetic field gradient is generally to 1T / m, in the rare earth permanent magnet roller separator machine, magnetic field gradients up to 100T / m.
The ferromagnetic objects (balls, mesh or steel wool) into the magnetic separator magnetic field can greatly improve the magnetic field gradient. The magnetization object (often referred to as media) can be produced when the magnetization of up to 5 * 104T / m local magnetic induction gradient. This innovation can greatly increase the range of magnetic force, so, can handle a lot of weak magnetic separator and even anti-magnetic fine particles. magnetic separation

Magnetic separation machine starting, stopping what strict requirements?

Domestic mostly magnetic separator magnetic separator imitation from abroad come, for now the most common Jones-type magnetic separator, its starting, stopping all have strict rules.
(1) First of all equipment before starting the gold surface inspection, to ascertain the reason for the last shutdown, if it is shut down because of mechanical failures, must be considered in order to boot troubleshooting.
(2) after making sure that equipment (including electrical equipment) is correct, the first pair of running equipment (such as pumps and host) for turning, turning one week after discovery rotation flexibility, no stuck phenomenon, indicating operation site accessibility, or to check and remove obstacles.
(3). Opened before the host to open the water valve and observe whether there is clogging faucets, check the pressure gauge, which means that pressure must meet the requirements of the value. Neodymium Magnet
(4) Start pump. Start pump, you must first open the cooling water, the oil ministries valve opens, and then start pump. After careful to check the hydraulic pump startup is normal, if there is leakage around oil, etc., be sure to make oil to maintain normal circulation.
(5) start the host, is operating normally, plus exciting current, be careful not to add a rating and should be added to the specified current ascending gradually. Non-transfected host first water, non-transfected host after the first excitation is forbidden host with a load starts.
(6) Host normal operation and immediately after excitation to the mine, pay attention to the mine can not have wood residue and other debris, can not have more than tooth plate gap mineral particles, can not have strong magnetic minerals. Generally in strong magnetic separator should be preceded by the removal of the weak ferromagnetic minerals, and use a sieve to remove large debris and mineral particles, in order to prevent tooth plate gap blockage. In addition, the mass fraction of the mine should be appropriate to the amount of ore to be uniform.tube magnets
Taking these six boot sequence can be obtained as follows: a comprehensive inspection of a water supply and a lubricating oil pump starts a starting coil cooling pump a starting host an exciting one to mine.
Stop into normal shutdown (ie preparation of downtime) and emergency shutdown (ie unprepared sudden shutdown due to an accident) are two normal shutdown magnetic sure to load the machine and then handle clean shutdown, shutdown and boot sequence order opposite.

The separator material selection to have a professional look

The importance of the accessories magnetic drum magnetic separator, magnetic separator equipment in the

magnetic separation work, always and material between the collision, so the magnetic drum magnetic separator

is prone to wear and tear. Badly worn, magnetic drum magnetic separator tube skin appears frayed phenomenon,

but once worn pulp enters the magnetic drum, which would be adsorbed on the surface of the magnetic system, overband magnet

has led to the drum skin with the magnetic system locking occurs, or slurry into the bearings leading to bearing

damage, but the damage to the machine is not working properly.
Permanent magnet drum magnetic separator for election do not fine-grained magnetite, or the mixed magnetic

minerals to remove the non-magnetic minerals. Permanent magnet drum magnetic separator tube surface

magnetic field strength is much higher than ordinary permanent magnetic separator, easy to operate and

maintain, and use of the various types of concentrator site has obvious energy saving performance. Oriental

permanent magnet drum magnetic separator magnetic separator cylinder can be equipped with three types of

tanks that half countercurrent tank (CTB), downstream slot (CTS) and countercurrent tank (CTN), to adapt to

different sorting requirements. Half countercurrent tank permanent magnet drum magnetic separator for the ore

particle size of 0.5 ~ 0mm roughing and is especially suitable for particle size of 0.15 to 0mm mineral selection;

downstream slot permanent magnet drum magnetic separator machine is suitable for roughing and ore particle

size of 6 ~ 0mm; countercurrent tank permanent magnet drum magnetic separator for the ore particle size 0.6 ~

0mm rougher and scavenger, and the coal industry heavy medium recovery.
For permanent magnetic separator the initial magnetic system structure. Sets in the magnetic system of the

cylinder wall with non-magnetic stainless steel, A3 steel pole plate, pole top corner on the use of NdFeB, the rest

of the main part of the ferrite. As can be seen from the distribution of magnetic flux density of the the initial

magnetic system structure, the magnetic field average can be achieved the 0.18T basically meet the design

requirements, but the pole midline and the magnetic field strength at the pole gap drops quickly, the magnetic

field distribution is uneven, the overall average field strength is relatively low. magnetic separator This is due to the ends of the pole

good neodymium-boron magnetic material near the pole midline ferrite materials caused. Must therefore be

carried out to improve on the original structure, using NdFeB evenly arranged, with a total amount of NdFeB

material does not change, only its tile pole surface.

magnetic separator composed of different decisions to different purposes

When we choose dry magnetic separator must go to understand the working principle of the dry magnetic

separator, dry magnetic separator in our understanding of the process, you will find an important role in the

efficacy of the use of the various components of different use efficiency determines the dry magnetic separator

scope of work and the ability to work, it must be when we use a professional understanding of these aspects. magnetic name tags
Magnetic roller in the sand dry separation machine to make normal use of the effect, the role is bigger on the sand

dry separation machine, we used magnetic drum magnetic field strength and reasonable adjustment of the

magnetic system allows flexible in use our magnetic roller in the separation of iron ore able to do the most

accurate separation, at a time when we need to pay attention is to maintain the cleanliness of the spear-drum,

when in use to better adsorption and separation of ore , so that the spear drum is the most important part of the

device. Role of the bayonet drum to be able to do the ore better separation, we adjust the size of the magnetic

force of the magnetic roller on the precise control of the current intensity must be done, and this can be done

under the control of the magnetic The adsorption and separation of the type of drum isolated on the type of ore.
We see an important role for sorting an important role in the adsorption and separation. High magnetic roller can

play an important role in our use is not to be ignored, the Director-General to the use of the magnetic separator, magnetic knife holder

we understand only use up to the current strength in separating what kind of ore particles can how to provide the

degree of magnetic, in order to do when we ore separation a very Chinese medicine, an exact separation of the

role of interest in the amount of ore.

Global NdFeB magnets changes in the industry with 25 years of development

Sintered NdFeB magnet energy product upgrade from the original of 35 MGOe (1983) to 57.8 MGOe (2004) is more rose to 59.6 MGOe (2006). Isotropic NdFeB bonded magnet of the magnetic energy product of 11 MGOe (1987), the anisotropic NdFeB bonded magnetic broom  nergy product of 25 MGOe (2001) has reached. Its global production of less than one ton in 1983 , the global production in 2008 amounted to 66,500 tons, with production of 5500 tons of bonded magnets, has reached 72,000 tons. Sintered and bonded magnets yield ratio of 92.4: 7.6. In short, NdFeB magnet industry have taken place regardless of the "quality" and "quantity" a undamental change it back out of the lab to become a global magnet industry. Today the global NdFeB magnet

NdFeB magnet will become a major commodity estimated after 2010. Today's global magnet industry is at a crossroads, and how to develop in the future, the road should be going? To give the correct answer, it is necessary for some in-depth and careful study of the global magnet industry. As the saying goes "learn lessons from past today, reflecting on the past, the the magnet industry today and five years ago, ten years ago is not the same, especially since 2005, the rare earth raw material prices rising structural! Current the metal neodymium

Price ($ 40/kg) is 3.6 times in 2005 ($ 11/kg). This has become difficult in the magnet industry is tantamount to worse. The sudden increase of the production costs and diminishing magnet, the magnet production in developed countries is difficult to maintain, forced to turn to the processing magnet downstream products such as components and assembly, magnet production to developing countries (mainly China). In the pressure soaring raw material prices, China's rare earth magnet manufacturers were forced to `make the appropriate adjustments: discard low-grade products, focus on the development of high-end products, the results yield decreased slightly overall, while the benefits are improved significantly, in other words, the effective use of rare earth rate, and enhance capacity for sustainable development of the industry.
