Mine shaker on our lives change

Mine shaker is a highly effective new screening equipment , widely used in mining, metallurgy , coal, building materials, chemical and other industries. His presence in our

lives caused enormous changes to make banana screen our lives more colorful , but also for the progress of our times has made no

Contributions may be underestimated . If you do not mine shaker appeared Maybe people screening technology also provides time to stay in the most primitive , manual screening

would reduce a lot of screening efficiency . If sand vibrating screen this did not produce an invention , the building materials industry would not have today , we might still live

In the last tile or cave . Mine shaker emergence of human civilization is a great progress , but also a jumping point in China's economic development.

    In the early mine appeared shaker, its impact on popular material , because of the level of refining steel is very limited , so that early screening devices were powered by

its iron structure. We all know that there are a lot of iron compared to the drawbacks in the present steel, for example, easy raw

Rust , the China Vibrating Screen surface is more difficult to clean and so on. Although later it will be difficult to be coated with a layer of oxidized material on its surface , which we call the

oxide film , but that film will gradually shedding layers after a long time , the surface will still be oxidized rust. Stainless steel eased this

Kinds of situation, the stainless steel surface can easily be cleaned , in this sense , the stainless steel is the best material in public places. Ideal ideal material for food

processing , pharmaceuticals , beer and chemicals : Stainless steel is relatively high , such as in a hospital or other critical areas , sanitation requirements

.

    Stainless steel eased the problem of mine shaker difficult to choose the material , but also in steel production and screening equipment industry has been more widely used .

In our lives , there are many things there are things that are made ​​of stainless steel , such as we use for cooking

The chopper , dishware, some companies use the restaurant , bowls , spoons , etc. , as well as home cooking pots and shovels are all made ​​of stainless steel used to build .

Stainless steel products not only will not rust , and the surface is smooth , easy to clean, is our best choice. We

Have to say , there is a large part of the credit must be attributed to mine shaker .

Historical mining sieve shaker

Mine shaker since the beginning it has been generated through a lot of changes in generations , it is also an important component of the screen during this period were great

changes. Shaker sieve shaker is wearing coal vibrating screen parts on the screen so the quality is directly related to the user's cost level shaker , screen

Types can be divided into : stainless steel mesh, stainless steel dense grain I-Net, so all kinds of stainless steel crimped wire mesh square wire mesh is widely used in

screening of solid materials , Mining vibrating screen screening, filtering liquids. Initial shaker screen is square grid is prepared by commodity grade wire

, Its life is shorter, screening efficiency is lower.

   Today I produced mine shaker sieve are used silk , metal wire or synthetic fibers such as woven materials , uniform and stable surface holes , with the role of screening and

filtration fabrics for industrial use . apron feeder Rubber and polyurethane to replace the original wire, by means of rubber and

Flexible polyurethane itself , reducing soil and ore screen bonding ; increase mesh stiffness, increase the opening rate , replace the canvas with a rope skeleton skeleton ;

improve the shape and arrangement of the sieve opening orientation , improving the material was sieved through rate. Holes ( mesh size sieve unit length often

) , Said width of each aperture is also useful to represent the .

    There are also a lot of time with stainless steel mesh material, not only durable , but also will not rust , it looks very beautiful. Stainless steel is mainly used for pH

conditions screening and filtering , the oil industry make mud network , chemical fiber industry screen, electroplating industry for acid

Net wash , gas, liquid filtration and other media separation . Generally made ​​of stainless steel to death, nickel wire, brass wire for the material. Today screen has been in

industry, agriculture , science and technology , defense and other fields has been applied. On to the cutting-edge technology , high-tech industry , down to the basic

necessities of life , cultural life

Live , simultaneous development of the national economy and people's livelihood solidarity. We will be more effort from top to bottom in the screen production , produce more to

meet the requirements of the mining vibrating screening equipment .

Mine shaker routine maintenance should pay attention to the small details of

Mine shaker there will inevitably be problems in the use of the process , if we do the proper maintenance and routine maintenance work in the process, you can reduce the chance

of problems with the equipment. In the process Feeding equipment of maintaining the equipment , there are many small details we need to pay special attention

Otherwise, a small problem can bring us great disaster.

   Mine shaker routine maintenance including maintenance sieve surface , screen, motors, bearings and other parts. Especially the screen surface fastening found loose in a

timely manner should be stone feeding machine slightly loose fastening ; regular cleaning sieve surface , the paint off the parts should be repaired , rust and paint

For bare machined surfaces should be coated to prevent rusting industrial Vaseline . Regular usage of the inspection apparatus and connecting the drive bolt lock , the belt

tension to check the extent of the shaker , properly tensioned when necessary. During normal operation of equipment should always observe the sieve concentrated ore

Degrees, so that the concentration of control in about 40% , in order to improve the classification efficiency ; always check the various parts of the bolt is loose, and whether

the screen frame and chute and other collisions.

    Check the sieve class support device , observe whether the apparent hollow rubber mat or degumming deformation , when the rubber pad is damaged or crushed when the

transition should also replace the two hollow rubber pad . For routine inspection problems should be promptly resolved, the problem can not be left behind , as well as

, Mine shaker after each use will have to clean the surface , so a long time will rust. Proper maintenance can extend the life of mine shaker , so for enterprises to create

profits in excess of its original capacity , faithful wish mine shaker development

Getting better.

Mine continuously reform shaker makes more delicate flour

Mine shaker has already been applied to the sieving flour industry , the emergence of the screening equipment allows us to taste the more delicate flour , millet flour and rice

. We all know that in ancient times , people are Tsuishine to eat, it was inside eating noodles and rice are mixed

Mingled with many of the bran and impurities ,crushing and screening plant  and taste very good. Still later invented a stone , like the wheat and corn crops into stone in moshan two or three times after it

becomes very delicate , and that is that people have been using the most primitive of screening equipment , using cloth made

Kind of screen, the image circle Feeding machine outside with a layer of wood the same thing . After the good things into our mill sieve sieve surface two or three times , it will distinguish

bran and flour , and then the efficiency is quite low .

   Later, with the extensive application of mechanization level of progress and power , people gradually invented a lot of power to drive the machines that can convert

electrical energy into mechanical energy , and thus to get some work done . That is, in this period, people invented automated

Flour mill machine , wheat through the machine , the machine from a bucket coming out of a very fine flour from another pocket of wheat out of the skin , which is what we call

the bran. In this way produce flour looks very pale , taste is also very good to eat

, So that this is a very great invention of mankind . Among them, an important role in crushing equipment is out of the screening equipment , and people screening device of

choice is mine shaker device , because the device lighter texture , durable and high work efficiency . Because a machine

Working time is longer than a day , so you must choose a better quality machine , so mine shaker became the best choice flour screening industry.

   In addition to the production of flour , as well as flour , starch production, as well as millet , rice production process often eat in our lives are inseparable from the

screening effect of mine shaker . As the economy continues to improve the level of people eating areas will be increasingly high requirements , which requires

Those of us in the machinery industry should continue to reform and improve , because in order to meet the needs of society.

problem can not be ignored , it is no coal crushing plant exaggeration to say that mine shaker and China economic fortunes are closely related.

The previous thirty years ago , China's machinery and equipment manufacturing industry which is still a blank field , but now it is not the same, has made great progress and

development , which the wise and industrious coal production line people of our country and our government the decision has a great relationship , to date, the

State vibrating machinery manufacturing industry than in the previous decade , the industry 's GDP has tripled above , it has a great relationship with the continuous

development of China's machinery industry, the mining machinery industry as a pillar of the shaker also experienced during a large degree of development. Because mine shaker in

a very

Many industries have been applied , so that mine development shaker driven development of China's machinery industry , animal husbandry, also largely driven by China's economic

development .

    Mine shaker applications in mineral processing industry has a history of nearly its main role is to beneficiation industry in mixed materials of different particle sizes ,

single or multi- screen and through a number of different levels of granularity into the process screening . Ore to meet the requirements of the straight

Then was shipped to the smelter to extract the precious metals , does not meet the requirements of the role of the particles to smash through the mill again , and then again

screening , know to meet the requirements so far. Later, with the continuous reform of society, it is applied to the tailings to recycle them , this

Application not only brings greater development space for China's economy , but also the country's resources to achieve the reduction, sound , resource disposal, is the

inevitable choice of China's economic development.

    Today, social progress requires the increasing levels of mechanization , which requires China's machinery industry to be kept reform. We have been convinced that " only

through their own areas of expertise Plough and thus sharpen their own personality , so that enterprises with

There are difficult for competitors to replicate and only let their own competitiveness. "

maintenance needs as good as to the possibility crusher plant manufacturer of the occurrence frequency of failure is reduced . The following are common feeder to the

Failure, and analytical solutions.


1 When the feeder load test is normal, the normal production of lower amplitude , low efficiency , is likely to be due to improper feeding port equipment design , equipment

trough to put too much load and stress. At this point in time on the inlet to improve and reduce the feed pressure equipment to ensure design

Prepared to work in a stable production environment.

2 feeder vibration amplitude is small , mobile crushers for sale can not properly adjust the amplitude of the exciter . Exciter is excessive voltage thyristor current breakdown , the gap between the

components or devices to be extra prone to this situation after the material clogging . Need to be cleared up clogging material , replace the exciter control

Silicon. It should be noted that the feeder after a long run in between the electromagnetic coil turn short circuit thyristor will happen , so that the thyristor rectifier

burned, causing equipment downtime , the need for timely SCR solenoid replacement .

3 noise and percussion work when the feeder , when the device when the amplitude irregular , prone to abnormal shock. Feeder plate spring was broken , loose or broken bolts

exciter and the tank will cause irregular vibration equipment to be tightened or replaced with new connection

Then bolt and spring structure , and maintain equipment, spare parts , such as between the core and the armature certain gap , and the need to adjust the motor control, keeping

the rated working voltage , avoid machine parts collide with each other and voltage instability during vibration .

(4) Upon power feeder , the device does not vibrate or intermittent work , current unstable. Feeder vibration motor coil wire fuse blows or a short circuit will directly affect

the normal operation of the device, resulting in no vibration feeder , a timely replacement of the fuse on the vibration

Structural features griddle trajectory classification and anti-vibration method

Griddle screen box because the trajectory is circular or oval but called circular vibrating screen. And because griddle only one axis, also known as single-axis shaker.
   Griddle griddle is divided into ordinary and self-centering griddle, the difference between them lies in the different coal crushing plant structure of the vibrator, the former center of the

pulley bearing center is located on the same line, when the griddle operation, pulley will immediately sieve Box shake together, thus causing repeated stretching of the belt is

leaving

Easy to damage, and coal production line require a smaller amplitude. Because of these shortcomings, the griddle has been rarely used in the production process. Self-centering griddle pulley center

is located between the center and the center of the eccentric bearing, and to the center line of the eccentric pulley blocks the body's synthesis and Vibration

Centroid, and therefore, when the griddle work, not with the pulley with vibration sieve box, the rotational movement produced thereby is also possible to employ a larger

amplitude in order to improve screening efficiency. Thus, self-centering griddle developed rapidly gained widespread application. Currently used in mine production

Griddle are generally self-centering griddle belongs to this type.

   Griddle in the activation and deactivation, since the resonance region, the amplitude of the screening machine speed will increase, causing severe overload spring to

shortened life expectancy, belts easily damaged, and it will affect plant construction safety. Damper device is used to eliminate the resonance phenomenon, Paul

Mine permit safe operation. When increasing the rotational speed of the vibrator to about twice the critical speed, the eccentric block pop work required to produce the

vibration force and amplitude.

Crusher market uncertainties exist

 Soon to be over in 2011 , China 's construction machinery industry showed a high to low development trend ; due this year for the real estate industry to take the national

macro-control , especially since vibrating screen supplier the third quarter, the high-speed rail investment slowdown , real estate, regulation , monetary tightening , etc. impact

Sales in the second quarter after the sharp drop in China 's construction machinery industry . Faced coal screening machine with the current situation, we need objective and rational analysis .

Construction machinery industry since 2007 short span of five years, has experienced two rounds of ups and downs , there is the impact of the global financial crisis and China's

macroeconomic policy changes and deeper after the Chinese economy, after nearly three decades of sustained high growth , China 's economic structure China's economic growth

Long way to adjust its internal requirements , which will have long-term impact on the whole construction machinery industry .

Factors affecting the crusher crusher from the entire market, there are many such as : the price factor , the price of steel prices , the price of ore , building materials , and

even house prices will affect the crusher industry , thereby affecting the crusher offer. For now, broken

Of course, the price crusher is mainly affected by the steel , market dynamics and other reasons , according to analysts , and now the steel market equities is serious, the

reality of the market mentality comparison , these two points around the crusher price , as follows :

An unstable steel market

Steel prices rebound, plus plenty of early market funds , directly pushed up futures prices of steel. Under the influence of money effect , the admission of new funds has

increased the market's rally is expected to make the steel market, the trend of the stock market currently growing , so

Changes led directly to changes in steel trading operation mode .

Second, the lack of confidence in the market

1 , this year's wave of market is mainly due to the low market purchases of small traders , focused on the release of energy procurement , steel mills shipped homeopathic

control , causing stock market specifications , and then pushed the benchmark price of the entire market . In the absence of significant changes in the major supply and demand

side , so this

Wave of market expectations mainly rely on the market to push .

2 , after last year's market test, the mentality of the majority of traders and mills tend reality , the concept of reasonable profits popular, so this year a large stockpile of

market traders less, to explore the potential market demand , timely service, earn traders more than a reasonable profit ,

A little of this and more , reflecting the maturity of the current market sentiment , and then to violent fluctuations in the market price of inhibition , causing minor

fluctuations in the market price highs .

Steel industry trend will probably change the price structure mining crusher equipment : With the sharp rise in prices of various steel , volume shrinking market , the trend of

price movements and outlook uncertain , steel prices and the continued high level of opinion bearish iron

Stone price formation is a contradiction . Late steel prices , the short-term risk is not great, but if the procurement needs of downstream users still can not effectively

released, the possibility of rising steel prices will not be great .

From the mining machinery industry sales situation, this crusher sales significantly downward trend , one of the most important factors affecting the price of steel by the

crusher prices will have some growth. Of course, the impact crusher pricing factors are changing , the need to buy broken

Equipment in terms of consulting businesses get more price quote information is necessary .

Mining vibrating screen for the first time check before five aspects

    Mine shaker After tuning in production, in order to ensure the normal use, you must first run before belt weigh feeder the shaker to make the necessary checks, shaker in operation before the inspection should be prepared in five main areas.
Mining vibrating Vibrating feeder screen for the first time before operation check:
   1, screen frame and base connection block is removed.
   2, the base is fixed properly. Fixing bracket can be used to carry out fixed.
   3, the fine mesh is paved.
   4, the fuselage frame beam ring screws are tightened.
   5, the body is in a horizontal state.

Feeder design and production parameters when

  I. Overview
Motor feeder is widely used in electricity, building materials , coal, metallurgy , chemical industry , food industry , used to transport a variety of non-cohesive bulk materials . It is not suitable for handling viscous materials or particle size less than 0.06mm powdery materials.

   Mechanical vibrations screening equipment in many cases be harmful, it affects the machinery and equipment performance and life. On the other hand , also possible to use mechanical vibration . Motor feeder principle is the use of the working parts of mechanical vibration generating periodic motion , which is used to transport materials

.
   Vibrating conveyor Circular vibrating screen many forms , structures differ greatly, the main difference is driven in different ways . Exciter currently used in three ways: the eccentric rod driven ; eccentric inertia -driven and solenoid drivers . Others include the use of hydraulic pneumatic device as a vibrating conveyor drive

Agency, but is seldom used. Benpian is the use of the motor feeder eccentric inertial force driven.
  Second, the operating parameters of the feeder selection
  Feeder operating parameters include the vibration frequency, amplitude , excitation angle , the installation angle. Reasonable choice of operating parameters is important to ensure the normal operation of the machine condition , it is not only to meet the needs of productivity , but also taking into account the machine can withstand dynamic load capacity and consumption

The magnitude of power . Besides transport efficiency is also often closely related with the motion characteristics of the material . So the choice of the operating parameters must also consider the physical properties of the material during transport and dynamic characteristics.
    1 . Mechanical index and throwing index
    Most feeder in the near-resonant conditions of work, materials thrown in a continuous state of motion , generally have high mechanical index . However, considering the level of productivity of the machine , and the conveying distance of the length of the vibrating mass size , to avoid the lack of rigidity and impact material being

Often transported . The mechanical index usually feeder control K = 3 ~ 5, throwing index control Kp = 1.4 ~ 2.5. Transportation brittle materials , the reduction of the material in the course of transmission is too much broken , should adopt a smaller throwing index , or in certain selected under high throwing index

Frequency and smaller amplitude , in order to reduce material and the whereabouts of the tank relative to the impact velocity .
    2 . Excitation angles and mounting angles
    According to the size excitation angle conveyor speed , tank wear and degree of fragmentation of the material requirements and other factors to select , in theory , can depart from the maximum transmission speed of the mechanical index to determine the optimal excitation angle . But in fact many factors affect the transmission speed , the need for full points

Analysis . Motor feeder and generally excitation angle β = 25. ~ 35 . .
    Tank mounting angle is the angle between the horizontal plane ( installation angle ) , the value of the conveying speed of the material influence . Tank mounted down , the feed rate increased significantly. If a = -100 , the conveying speed can be increased about 40% ; α = -15. Can be increased by 75 % or more. However, α values ​​are not

Should be too large, because it not only exacerbate the wear material on the tank , but also by the natural angle of repose of the material limitations . Generally not more than 10. 15 . .
    3 . Frequency and amplitude
    Feeder drive used in different ways, to adapt his range of frequency and amplitude is not the same . To increase the transmission speed , lower frequencies should be used and a larger amplitude. It should be noted that the material falls trough the relative speed and inversely proportional to frequency , so the test

Consider reducing the relative impact velocity material ( for friable material ) should adopt a higher frequency and smaller amplitude.
    The eccentric inertial vibration feeder , due to the eccentric mass and the starting torque limit , the amplitude of 0.5 to 6 , corresponding to a frequency of 12 to 25 Hz , the frequency is too high due to the large dynamic loads often the bearing premature damage.
    4 . Transmission capacity
    Feeder transmission capacity by the width, material thickness , material density and actual average delivery speed decision.
    For different materials, transport of material thickness have different restrictions , such as more than its limit , transmission speed will be greatly reduced. Material thickness and the conveying speed between three cases . Where I is a thin material layer , in this region , the conveying speed with the thickening of the material layer

Rapidly , and soon reached the maximum. Ⅱ area is moderately thick material layer , transmission speed depends mainly on internal friction of the material , and with a slight decrease in the material layer is thicker . Ⅲ area belongs thick layer, in this region , due to breathable material conveying speed decreased significantly reduced .
    Third, the kinetic parameters of the feeder
    Motor feeder axis inertial shakers can generate directional excitation force . Between the two axes of the drive with a gear ratio of l pay connections ensure its rotation in the opposite direction , speed equal. As the two -axis eccentricity of the eccentric mass and the same size , so that the inertial force generated by a

Directions cancel each other , overlap each other in the other direction , the exciting force generated orientation . This force changes periodically , so that a rigid connection with this shaker conveyor trough also be directed periodic vibrations.
    In our study the dynamics of the feeder , the eccentric block is ignored during the rotation unevenness of the vibration parameters of the system , that it is a constant rotational speed . So that you can take it as a mechanical model with a degree of freedom of the system to study . Centrifugal force

Press harmonic changes simplify the calculation process , are close to the actual situation .

A feeder Classification and working principle
    Feeder oscillating screen at excitation can be divided into : electromagnetic vibration to the Branch machine, vibrating feeder and inertial self-synchronous resonance feeder, although structurally different , they are all from the tank, exciter and damper composition , this paper introduces the use of self-synchronous vibrating feeder relevant knowledge , self-

Synchronous eccentric block feeder motor inertia force generated by the connection of the two axial direction of the offset , and the two direction perpendicular to the axis is superimposed on the connection of the exciting force , is this exciting force materials vibrate.
Two self-synchronous operation mode feeder
    When transporting friable material or powdered materials , often using materials sliding mode, that material is always in contact with the bottom of the tank , the tank each vibration cycle , the material on the slide for some distance , so that the tank continuous vibration at certain frequencies can be material handling to go . But this tank vulnerable

Wear and tear , so no special requirements when transporting crushed material , the use of throwing motion , that is the material continuously forward tank top toss for parabolic motion , and then fall back to bottom , every toss once, some distance ahead . This approach is characterized by wear tank lighter materials

Conveyor speed is higher. Most feeder Saikawa throwing movement.

Vibrating feeder isolation methods and design principles

But after using multiple vibration isolation system , equipment

The structure is much more complex , the weight also increases.
    Feeder vibration isolation system parameters of the calculation shall meet the following requirements:
    ( A ) the feeder should be good and to be able to meet the needs of practical work isolation effect , that isolation factor should be smaller than a certain allowable values.
    ( 2 ) After loading , feeder amount of subsidence should be less than the allowable value .
    ( 3 ) feeder vibration during operation should not spring from work the body and have an impact and noise.
   Isolation system in feeder work plays an important role , and its direct impact on the design of the feeder is working. According to the design principles of the design of this feeder vibration isolation system safe and reliable, it allows the feeder to pass a building dynamic load significantly reduced. The design method

Dexing Copper Mine and many other applications to be a strong confirmed.

Air screen history of the development

Each device has its own research and development to production unique job functions , air sifter as a professional fine powder screening equipment , a lot of calcium powder

manufacturer is no stranger .
Airflow sifter available mining vibrating screen
 from 1992 has gone through two years of history, in the continuous development and improvement process, get a lot of help and support the use of

manufacturers , R & D airflow sieve purpose is to filter a variety of fine flour sieve difficult . Because powdery material surface area, easy to drift

Float flying, Sand screening machine if not easily over the net with a vibrating sieve , causing environmental pollution, perishable sieve mesh with a scraper with a winnowing machine fineness

imprecise , and high power consumption . Air screen in recent years in the promotion of third-generation and fourth-generation air screen technology research and development

process .
The greatest feature is the air screen large output , high efficiency, non-stick network, do not plug the mesh fineness precise and so on.

Ultrasonic vibrating screen which causes abnormal

① ultrasonic vibrating screen is not installed correctly , the basic exciter shaft and the shaft is uneven or off-center too ( if connected with a universal coupling , more

prominent ) .

② shaker moving parts and apron feeder chute, hopper and other parts do not move between the card of a foreign body .

③ feeding inequality causes partial load, even without the screen surface while feeding .

④ sieve fixed is not strong or damaged , resulting in secondary vibration .

⑤ different positions of the support spring stiffness disparity or fracture occurred.

⑥ ultrasonic weight feeder vibration sieve and a first natural frequency and resonance frequency of the same .

⑦ exciter assembly is poor, such as the double box-type shaker , shaker vibration direction when the two angles are different. Will cause both sides of the sieve vibration

direction angle inconsistent.

⑧ ultrasonic vibrating screen design is unreasonable, improperly positioned center of gravity , the direction of the exciter force failed to pass the center of gravity , large

deviations .

⑨ in shaker box using two interconnected large vibrating screen , after several run after overhaul prone to unusual circumstances , such as torsional vibration , material

deviation, sieve plates fracture , etc., mainly due to the exciter is 2 is equipped with primary and secondary eccentric shaft composed of two axes and then by two identical

Gear is connected , this structure ensures two axes synchronized with the speed of reverse rotation, so that the two axes of the exciting force superimposed , resulting in a

certain angle with the horizontal exciting force , in fact, the exciting force of the force direction entirely by eccentric eccentric position of the decision, which rely on the

two gears being meshed

To determine the correct position of the correct position of the eccentric . Due to the direction and gear meshing force Centrifugal force causes change, such as two exciter

force direction angle occurs when the ultrasonic vibration sieve torsional vibration occurs . Similarly , when connecting two ends of the exciter shaft flange bolt holes

dislocation,

Also produced similarly to the above case . So, when these cases will occur shaker is not running properly , and one of the torsional vibration sieve harm even worse.

Swing sieve vibrator how best ratio

Oscillator rotating weight on the screen surface can produce planar whirling vibration , and the lower rotating weight you can make produce cone rotary vibration sieve surface ,

the combined effects of the vibration screen screen surface can produce complex rotary -type vibration . Here to introduce the next screen using standard swing weights ratio:
1 If you are using the flange vibration motor , counterweight ratio of 3:1
(2) If it is used in vibration motor flange , counterweight ratio of 4:2
3 If you are using ordinary motor , when the weight ratio of 1:1 is most stable .
Swing sieve with weights proportional not independent , needs and swing angle screen interaction . For better feeding equipment  screening effect , to the proportion of the angle and material

properties of the three unified regulation.
Currently on the market swing and sway sieve sieve has two motors . One is in the flange type vibration motor , the other is on the flange type vibration motor . For some

special industries mainly in the use of materials screening vibration motor flange . Some southern enterprises to adopt the common motor to bring

Move swing sieve work , such a structure is very unstable , the failure rate is high, such a choice is not recommended .
