installation and commissioning and trial operation
Installation
Separators There are two installation methods, namely the head mounted on the conveyor belt or the middle. Where conditions permit, particularly at high conveyor speed are adapted to be attached to the head, then the suspension height can be increased, but please note that the first round of the conveyor must be replaced by a non-magnetic materials, otherwise it will seriously affect iron removal results.When the separator installed in the central belt, the two rollers must be greater than the distance between the separator body width, or a group of idlers shall replace the non-magnetic roller. To enhance the effect of iron separator should be installed below the level of a non-magnetic roller, and it is higher than other rollers 50 ~ 150mm.
 Check the separator body reducer and electrical performance (coil resistance and insulation resistance), can be installed without problems.
Separators bench with four lifting lugs for installation, spreader should have sufficient strength, and adjustable suspension height.
Separator should be installed as far as possible so that the work gear position in the horizontal position, for maximum tilt angle should generally be less than 15 °, and the output shaft of the shaft end down, more than 15 ° measures should be taken to ensure adequate lubrication and prevent oil leakage.
 Unloading iron belt deviation and adjusted
Check the unloading iron belt, if the deviation phenomenon can be adjusted:
 Unloading iron belt deviation to the right of the forward direction adjustment method: on both sides of the bearing adjusting device evenly adjusted so that the driven pulley and the belt forward direction at right angles, and then on the side so that the belt deviation roller moves the same distance in the forward direction Finally the bearing adjusting means for tuning.

 Unloading iron belt direction of deviation in the forward direction on the left to adjust the direction: the same with 7.4.1. Make left at the same size roller moves in the forward direction, but also allows the right of the back roller same size, and then fine-tune the bearing adjustment device.
Note :: (1) Please be careful not to unload iron belt tension too tight.
(2) unloading iron belt separator body to adjust gain and a, b two o'clock slightest touch.
 To run power reducer 0.5 to 1 hour, no exceptions can be used normally.
8 Cautions
 If the down time is longer, again, the need for electrical performance gear check. Powered insulation resistance measurement be carried out before. The ambient temperature is 0 ~ 40 ℃ and relative humidity of 50 to 70%, the insulation resistance value should not be less than 10MΩ, damp should not be less than 1MΩ, when discovered insulation resistance value is less than 1MΩ should be dried processing, recovery, 1MΩ more to continue to use.
Separators near a strong magnetic field, so it shall be placed around the clock a class instrumentation.
 Reducer operation, check the lower belt electromagnetic separator body absorb iron pieces around whether and, if you must clear, otherwise it will damage the belt.
9 Care and maintenance
 Special fault does not occur as long as the separator, the usual regular inspection and maintenance are mainly conducted its surrounding dust Ex cleaned regularly refuel the bearing.
 Unloading iron belt and gear power cord should be regularly checked and found that trauma, timely replacement.
 Reducer for use:
 Reducer with pendulum pin gear meshing, planetary transmission principle. Reducer rated speed of 1500 rev / min, allowing both positive and negative direction.
 Reducer used under normal conditions in the oil bath lubrication, the oil level sight glass held in the middle of the can. Lubricants recommended E90 # extreme pressure gear oil can also be used 40 #, 50 # oil instead. Refueling rotary power seat ventilation cap to refuel unit, put oil rotary power seat bottom drain plug, the oil can be released .
 The first 100 hours of operation that is fueling a new lubricant should be replaced (and internal oil rinse), later replaced once every six months of continuous work (eight hours). If the condition is severe, you should shorten the oil change time.
Lubricants during use should always be added.
 Gearhead eyebolt lifting gear only.
10 unloading iron belt replacement
 Loosen the sprocket guard bolts, remove the cover and chain.
 Loosen the main bearing from the wheel pulley mounting bolts, remove the pulley from the bench, bench side idler also be removed.
 Loosen the separator body mounting bolts, remove the body from the bench, and then you can start a new belt package (non-magnetic blade should be installed, fastening and welding stopper), note the direction and unloading iron belt scraper run direction.
 On the ground put two wide planks, will unload iron belt on it.
Roll up the side of the separator iron unloading belt and the main body, insert the belt driven pulley inside (with a crane lifting)
 The gantry crane to the top of the separator body and fastened with bolts body bench.
 The main, driven pulley and idler alignment fixed after strong stand in, please note the main, driven belt parallel and with the same size of the gap inside the gantry.
 Installed chain, chains and regulate the tightness of the belt, cover shield.
 Make sure to check all bolts tightened after a good start reducer, if the unloading iron belt deviation phenomenon appears, press the 7.5 to adjust.

the magnetic pipeline of new modes of transport

September 18, Baotou Rare Earth Development Zone, a hall, a researcher gently press the push-button. With the powerful current input, a simulation of solid material carrying cargo quickly through the annular conduit of 80 meters, the analog materials transported to a predetermined position accurately. This is China's first maglev line pipeline transportation miniature pilot demonstration site, it's built and test success, marking a new mode of transport --- magnetic pipelines birth.

"Maglev" concept is not new to us. 10 years ago, the Shanghai building the world's first maglev train magnetic tool operating line, had the "maglev" This concept is well known. From a technical point of view, with different magnetic levitation train using superconducting magnets, the magnetic core technology pipeline transportation from the United States "maglev aircraft" used in the process developed linear synchronous motor technology. This technology is relatively mature in the United States, but China will apply to their pipeline transportation system in the world is the first time, there are many technical bottlenecks need to break.

内蒙古麦格普林 magnetic pipeline technology limited liability company with the United States Magnetic aircraft technology companies, researchers after a difficult technical research, and finally in pipeline transportation maglev technology has made breakthroughs in key technologies, and built China's first maglev pipeline transportation miniature pilot demonstration line. The demonstration line length of 80 meters, fully enclosed by a ring-shaped pipes and magnetic levitation warehouses of two parts. System is running, the pipeline's linear synchronous motor generates strong magnetic impetus laden position 10 meters per second, the speed of progress.

It is understood that on September 18 the successful test for the next test provides a comprehensive, detailed technical data and research experience in the construction. According to the schedule, then the project will also build one km and 12 km small demonstration line commercial demonstration line, this new mode of transport will ultimately lay the foundation for building large-scale investment.

According to the person samarium cobalt magnets in charge of the project, the transportation system to adapt to a variety of complex terrain, and not subject to climatic and environmental impact in the economy, energy, environmental protection, efficiency has other means of transport can not match advantage. Small postal parcels, large coal, ore distance transport, pipeline transport through magnetic, simple and convenient. Experimental data show that the diameter of 1100 mm magnetic levitation transportation system in the short-distance pipeline transport, coal, iron ore and other solid materials, annual transportation capacity of up to 5 million tons to 15 million tons. In transport costs, the advantages of magnetic pipelines more prominent. It is estimated that in the case of the same material transport, pipeline transport of magnetic power consumption cost is only 6% of the cost of fuel trucks. Moreover, the use of magnetic pipeline for transport, almost does not emit any harmful gases, the ecological environment will not produce any side effects.

My area is a resource region, particularly rich in coal resources. Like many mines and the national, most of our region's various mines located in mountainous terrain or Mid some mineral resources buried deep, so the construction of pit road or transport the ore from the mine face transported to the wellhead are very difficult. The traditional belts, small rail car high transport costs, low efficiency, it is difficult to meet in a short time a large number of large mining minerals shipped out mining site requirements. In this regard, the magnetic pipeline transport will come in handy, its transportation capacity, rapid and efficient features, will effectively solve our region's various short-distance transport of mineral resources.

Some experts called this new mode of transport following the rail, road, air, water and conventional liquid transport pipe outside sixth modes of transport. Miniature magnetic pipeline transport model line test success, scientific and technical cooperation in our region is a successful example, but also my district technology personnel in the transport technology a major breakthrough, its practical application and future development prospects.

. The disc with the upper rope mine management, the following connected with trenches, and in the rope with the corresponding parts of the tube mine to mine mouth, so that the separator is formed on the good overall, but also

Is SHP type wet strong magnetic separator different from other magnetic separator unique. New era and a new starting point, we are also full of new machinery and equipment to be utilized, plus

Fast pace of development of new community.

Separator is used in the powder particle recycling removal of iron in the body, are the most widely used industry, high versatility is one of the aircraft, and is widely used resource back

Closed, timber, mining, ceramic, chemical, food, and other factories. In the process of magnetic separator for each mineral particle size or a certain requirement, the current World

Circles on each piece of equipment samarium cobalt magnets is not perfect, dry magnetic separator is the same, it does not fully adapt to different mineral particle size. In actual operation, magnetic separator,

For the coarse, medium and fine has certain range requirements, and is not the same as those of the magnetic particle can be achieved is not the same effect.

, On the susceptibility of weakly magnetic minerals is constant, it is not the field strength and mineral particle shape change, only with the composition of the mineral itself, there is no

And the residual magnetic hysteresis phenomenon. Weakly magnetic minerals than the susceptibility is relatively small, weak magnetism, we order to facilitate research, some of the illusion of hematite, ilmenite and other magnetic

Minerals are classified as weakly magnetic minerals ranks to study and found that even at high weakly magnetic minerals under the effect of external magnetic field, magnetic saturation is difficult to occur. As for the strong

Magnetic minerals, it is not a constant than the susceptibility to increase the selectivity of the separation, magnetic products to improve taste, but with time should be increased in order to compensate for the excitation current

Increase the pole pitch and reduce the magnetic field strength; sweep the election as far as possible the extent of the work space to the minimum in order to improve the recovery rate.

Separator is the company with the characteristics of domestic magnetic separator, developed a new type of magnetic separator. The best performance at home and abroad, technology first

Advanced magnetic separation equipment. High gradient magnetic separator using vertical rotary swivels, recoil concentrates, and is equipped with high-frequency vibration mechanism, from the fundamental solution to the flat ring magnetic separator

Peace ring high gradient magnetic separator magnetic media clog the technical problems. It has a large enrichment ratio of feed size, concentration and quality fluctuations adaptable, reliable

Operation and easy maintenance. High gradient magnetic separator sorting the weak magnetic ore concentrate to achieve a high grade and high recovery of double height advantage. ,

Since the width of the magnetic system, the magnetic field strength changes in the axial direction is not the same. Small width of the magnetic system, the closer edge magnetic system, the magnetic field strength is lower, under

Drop tremendously in width large magnetic system, a large range of magnetic field is uniform, magnetic separation in the selection process is rarely used as an independent work, it is mostly related with the re-election

, Flotation beneficiation process and electrostatic matched in recent years, and with the shaker gravity flotation process compatible. Magnetic separator magnetic system, the use of high-quality ferrite and rare earth materials or

Magnet compound from the previous tube sheet average magnetic induction intensity 800-4000mT. At present, because the development of technology, can be made into a roll magnetic separator, magnetic field strength is also increased to

8000mT, has been measured is the highest field strength. Although the magnetic field is the use of the role of the work,

Only use protective wear layer tubular skin, magnetic separator life will be longer and can be more assured of using magnetic separator magnetic separator equipment is a common mineral processing equipment,

Differences in the use of magnetic minerals minerals choose another one device is the use of the magnetic characteristics of the fine ore minerals choose another production capacity is very strong, is widely used

Causes.

In addition to the magnetic mineral separator contributed magnetic mineral separation technology is now developing rapidly, is a typical product of magnetic separator, magnetic separator using the magnetic field distribution is

Magnetic minerals by the same size is different, effective magnetic substances like mineral separation, in the current common bauxite, limonite, hematite and other minerals

Sorting in Liledagong.

Magnetic Separator in use much water to use, such that we referred to as wet magnetic separator magnetic separator, there is no water we call dry magnetic separator. Wherein the moist

Magnetic separator into downstream type, counterflow, semi-counterflow. This is magnetic separator magnetic separator in slurry flow and the direction of rotation of the drum different decisions. Need to see concrete

Mineral specific analysis. Magnetic Separator principle is very simple, is to use a magnetic mineral ore on separate devices for things, but how accurate sorting of minerals carefully

, We need the guidance of a professional.

The method of adjusting the tank in the support frame pivot point subtraction of the four pads. Because the position of the cylinder is fixed, plus washer tank after increased work space becomes

Small; reduce gaskets, working gap becomes larger. Working gap size should be uniform in the axial direction, if the size of the gap ends are different, resulting in slurry flow rate range, the gap

One end of the body due to a large trough may produce ore slurry flow rate low deposition, or even blocked. Plug one end of the tank can be observed phenomenon is clogged suction side surface of the skin is not on the tube

Concentrates, working gap can be accurately measured when the overhaul, such as copper associated with gold, and silver-gold ores associated with arsenic. So check out the ore of

Chemical composition and the content is very important, we need to determine what can be recycled and which can be dealt with. Helpful, given the state of harmful elements, it is useful means

And what form harmful ingredients present in the ore, if the form of an independent mineral beneficiation methods when the available physical treatment to isomorphism exists when the
