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 .

Failure to common feeder Brief

Feeder device is the latest developed models, power, energy efficient, good wear resistance properties and long service life . Feeders like other mechanical equipment

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

Moving coil layer between the motor turns occasionally check to exclude short circuit , connect the lead line .

apparent in 2013 , leading enterprises will have more market, small businesses will be very difficult . Follow the market development path , and stronger they are each broken

Common development direction machinery enterprises .

Fourth, the development of overseas markets into the mainstream

       For a long time , in the face of overseas markets , Chinese companies have been admitted by . However, with the continuous development of Chinese enterprises , China's

construction machinery has the strength to compete with international giants . Trinity acquired at the beginning of the German giant has revealed the strength of China's

construction machinery . Not

Whether it is going to acquire worth mentioning, or in the overseas construction base worth mentioning, the overseas market , our country will not hand over .

Five fire from the secondary market

       With the transition of economic development , the allocation of social resources will be more rational optimization, used equipment will become the new way of the

survival and development of construction machinery industry 2013 . On the whole , China's excavator market in second-hand refurbished , still in terms of re-manufacturing

business

Infancy, used construction machinery market has not and refurbishment , remanufacturing business interact , but this does not affect the used machinery in the Chinese market

since the fire .

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.

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 .

Shaker vibrates the main bearing

Bearing vibrations are mainly due to bearing rotates under the action of the load , causing the deformation vibration of bearings .
  1.1 Vibration bearing rings
  Vibration is essentially a rolling vibration screen bearing of the vibration of the bearing rings , the bearing structure , rigidity , precision manufacturing , installation , and usage

conditions and other factors. If the bearing inner ring raceway has a larger radial corrugations , the inner bearing outer ring rotation will produce radial vibration . Bearing

inner ring will not only cause a corrugated outer radial vibration , but also will cause axial vibration of the outer ring , coal screening machine the bearing will be subjected to axial load the

bearing , the outer ring of the axial relative position of the change, so rotating the inner ring of the bearing outer ring also produced mouth axial vibration shaker at work ,

for high-speed rotation of the bearing , because the ripple caused by the vibration frequency, there may be equal to the rotational frequency of the exciter shaft , which

produce resonance .
  Cage vibration 1.2
  Vibration of the cage , mainly due to the rotation of the bearing retainer and rolling vibrating the vibration generated by the impact on each other . Vibrating screens , the

impact load accompanied by various alternating load , will cause severe vibration of the holder , the vibration is generally believed that " due to the rolling element and the

sliding friction between the cage retainer induced from excited vibration .
  Vibration is mainly produced in the retainer ball bearing and tapered roller bearing in the radial gap is too large , good lubricating properties , shaker exciter shaft

transmission torque fluctuation such circumstances likely to occur.
  1.3 rolling body vibration
  In a large shaker ball bearings and roller bearings , when the bearings mainly take radial load and low-speed rotation , it will produce the whereabouts of rolling vibration .

Trial found that when the bearing radial load and grease in case of poor performance , early operation will hear "click \ Kacha" sound vibration , which was mainly due to the

load zone of rolling after leaving suddenly accelerated and cage collision and vibration emitted sound , this crash is inevitable but will disappear after a period of operation

.
  When the bearing radial shaker operating under impact loads , only a few months of its internal load bearing rolling elements , because the elastic contact with the ferrule

constitutes "springs" which supports the rolling line of action of the radial load generated through periodic oscillations ( and therefore at the center of the vertical shaft to

move or do horizontal movement ) . Especially in the low frequency vibration shaker , the type of vibration is more obvious .
  1.4 Friction Vibration
  Rolling friction vibration mainly refers to abnormal vibration , friction and vibration in general in a large ball bearings prone to using grease lubrication performance

particularly bad fats are more likely . According to the test and observation , bearing friction and vibration generation often has a direct relationship with the oil properties

. When lubricating performance is not good , or dirty , then the friction vibration prone , but also with the bearing outer raceway processing quality , and if this method of

using special precision machining , can be better controlled friction stir .
  Rolling over the vibration is often the result of various types of vibration . Tests showed that the bearing operation under normal circumstances , bearing parts bearing

surface waviness is caused by vibration of the main factors.
