Why Circular Vibrating Screen can not Start up and Amplitude is Small ?

Days ago,my Russian friend asked me why circular vibrating screen could not start up,however,the amplitude was quite small even if it start up,and the screening efficiency is quite bad,here I summarize the reasons as follows:
1.The circular vibrating screen motor breaks down,please replace the motor;
2.The electrical equipment control circuit fails,please maintain and replace the electrical equipment;
3.The voltage is low,you can alter the power supply;
4.There are many accumulation materials on the surface,please clean up the material;
5.The screen itself has fault,please check and maintain the vibrating screen;
6.The lubricating oil is over thick or caking,please clean the screen and add new lubricating oil;
7.You can also add balance weight to increase the amplitude.
Besides,please also note that the adjustment of vibration source on vibrating screen(exciter or vibrating motor) must be same,or it will cause equipment damage.

Vibrating feeder installation commissioning and maintenance tips

1.Vibrating feeder is used for batching and quantitative feeding material to ensure uniform feeding stability,horizontal installation should be adopted to prevent self flowing, declined10 degree installation should be adopted if there is continuous feeding, declined 15 degree installation can be adopted for viscous material and large water content material.
2 .After the installation, 20mm level lateral clearance should be left for vibrating feeder, suspension device should adopt flexible joint.
3. Before non-load test, please fix all bolts, especially the anchor bolt of vibration motor tighten the bolts again after continuous operation for 3-5 hours.
4. Two vibration motor must be reverse rotation when test run to check the current and noise stability, if any abnormal conditions, please stop the feeder and solve it timely.
5 Motor bearings should be lubricated every two month, for high temperature season bearings should fill the lubricating oil every month.

Small part with large effect : Vibrating Screen damper

Do you know Circular Vibrating Screen damper?it’s a device which limits vibrating screen horizontal vibration.
May be you feel puzzled,is there any vibration in the horizontal direction?The answer is no In theory, but the practice has proved that it exists, the reasons are as follows:
(1) The distribution of material on the screen mesh is uneven. 
If the material is uneven,it can lead to the uneven force for screen box ,thus vibrating error appears.
(2) Installation error.
The Circular Vibrating Screen needs horizontal installation,but in the process of installation, the error will inevitably occur, resulting in a height of four supports occur small deviation, but the small deviation will be amplified by the vibration exciter, thus it will result in greater vibration deviation.
(3) the stress error of the spring.

New dust removal method for vibrating screen

Most of the Dust removal method of supported type vibrating screen in our country is cloth bag dust removing technology, which includes cover dust catcher, pipelines, cloth bag dust collector, induced draft fan and chimney, etc. The advantage is high dust removal efficiency. However,the disadvantage is large investment, low dust collecting rate, easy blockage of horizontal pipeline, large pumping air volume, high operating cost, big occupied area of dust catcher,induced draft fan and chimney, besides, it needs to set up full-time operation& maintenance personneland the dust transport equipment.
In order to solve the above problem, we have researched a new resolution with high rate of dust removal system, low processing cost, long service life, less investment, small area coverage and short construction period.
The new dust removal method offers secondary dust removal for supported type vibrating screen.Primary dust removal equipment will fixed above the vibrating screen,collected dust will enter into vibrating screen; Secondary dust removal equipment will be placed near vibrating screen and remove dust by itself.
Primary dust removal: seal the supported type vibrating sieve surface and set a dust filter above it,set up an efficient filter bag to filter the air, clean air will be discharged through 3.0 kW fan, thus dust will enter into the vibrating screen through the bottom of the filter. Vibrating screen drives sieve surface vibration,while the dust filter is fixed, so one moveswhile the other one not, both connected by the pipe, the joint connection adopts rubber to reduce the vibration.
Secondary dust removal: Seal the supporting type vibrating screen and dust removal joint, leave a open mouth to connect the pipe for conveying the escaped dust into the secondary dust filter,set a high efficient dust filter bag to filter the dust, and then the clean air will be discharged through 3.0 kW fan, then the dust is discharged from the filter at the bottom of the tube and the valve.

What is the selection notice of rotary vibrating screen?

1.Size of working area: rotary vibrating screen is circular, sieve surface area will effect of screening yield, so screening efficiency and yield can be improved by increasing the screening area. So the size of the field is one of the keys to the vibration screening.
2.Material characteristics: material properties,flowability and size.
3.Construction material : because of the different sieving materials, the construction material is also different, for example: food, salt, sugar and other related food industries, the whole machine material is SUS304. One reason is that hardness,thickness and wear resistance of 304 material are better, besides, polished stainless steel is bright like a mirror, the surface is clean and health, maintenance is very convenient which do not affect the material quality after screening. If the material is chemical, metallurgical and other raw materials, you can choose Q235 material, which not only save cost but also not affect the use.
4.Screen mesh can be divided into two kinds: stainless steel and carbon steel.
The shape and size of rotary vibrating screen are different generally based on the actual application and the on-site condition, and can be designed according to the requirements of clients to meet special circumstances. Common types of rotary vibrating screen: XZS-800mm, XZS-1000mm, XZS-1200mm, XZS-1500mm, XZS-1800mm, etc.

What is the Helpful installation tips of vibrating feeders?

Vibrating feeder is generally used for evenly, regularly feeding, distributing bulk material in different production lines to guarantee the steady connecting between the upper and bottom equipment. When feeder model is small with little capacity, the drive device can be 2 sets vibrating moor; while the feeder model is large with heavy capacity, the driven device can be 2 sets motor and vibrating exciter. It will be selected according to the actual technical requirements. 
In addition, vibrating feeder can be designed to be seated type or hanging type according to the on-site working condition and installation space. 
When vibrating feeder is installed under the hopper or silo outlet, and there is no enough or suitable installation foundation for vibrating feeder, it can be hanged with hanging devices to save the installation space,which makes the equipment connecting more easier. 
If the customers require seated type,vibrating feeder should be installed on embedded foundation.
If the material size is very small,similar like powder, dust etc. The vibrating feeder can be enclosed with dust hole and connect the dust collector in system to protect the environment. 
If any special requirements, vibrating feeder can be customized to meet the special technical requirements.

Introduction of Vibration Platform

Vibrating/Shaking Platform is the device mainly used for reducing air and crannies among the material to compress the material; it is always used with silo.

►  Working Principle
Unbalance motors make the platform to oscillate. An oscillation insulating elastic suspension connects the top and bottom part of the platform. The amplitude of the oscillation can be changed by adjusting the unbalances on the unbalance motors during standstill. Besides, the vibration frequency can be changed during the operation time if an electric control with frequency inverter is being used. Both parameter have influence on the vibration intensity and allow an adaption to the different scopes.
