Test During Commissioning

A commissioning test video for a wooden chips circular vibrating screen, which will be delivered to Thailand. After assembly, each set machine muct be test running in our workshop. During commissioning, the Quality Control Engineer will inspect each technical parameters, to guarantee the equipment be qualified.

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.

Differences between the YK and YA circular vibrating screen

When customer choose and buy circular vibrating screen, YA and YK series of vibrating screens are optional. So what's the difference between the two types of vibrating screen? Which series should choose? Here,PK Machinery answers for you.
In general,YA and YK belong to circular vibrating screen series, YK series block type eccentric circular vibrating screen is updated products of YA axis eccentric circular vibrating screen.

 

According to the research,development and the application level of domestic and overseas vibration machinery , bring in the advanced technology in the same industry of Germany, Japan and other countries, combine with the actual running environment,our engineers fully optimize and design a new type of high efficient YK series vibrating screen.
In addition,retaining the feature of the original YA type axial eccentric circle vibrating screen,YK series circular vibrating screen has the following significant advantages:
1.Exciter adopts eccentric block form which not only makes the single heavy exciting force of the eccentric exciter weight increase, but also exciting force can be randomly controlled, so it is easy to modular design and use;
2.Simple machine structure is beneficial to improve the level of equipment manufacturing technology and assembly accuracy;
3.Using the flexible connection of cross axle cardan shaft or rubber coupling etc which makes running smooth;
4.Sieve machine is more efficient with greater capacity;
5.Using cycle and service life is longer;
6.Equipment maintenance will be simple and convenient,the machine running efficiency is improved significantly.

What reasons lead to material accumulation phenomenon of vibrating screen?

Some customers said material accumulation phenomenon occurred in the use process of vibrating screen, according to many years of analysis experience, the reasons can be summed up in four aspects:
1.There is a problem of vibrating screen mesh selection, too small mesh will cause a low rate of material passing through the mesh.
2. Check whether the ground level of the vibrating screen is flat or not, besides,high material inlet will affect the material running track, resulting in material tilting to one side.

 

3.Check whether the screen mesh and outlet are horizontal or higher than outlet or not, under normal circumstances, it should be horizontal or 6mm higher, the design is not the same according to different material discharging outlet.
4.There is a problem on the vibration motor angle adjustment, improper angle adjustment of vibration motor will cause material accumulation, if the angle is small,the material will spread outward quickly on the sieve surface,while if the angle is large, the spreading speed will be slow. If you have strict requirements of screening accuracy, the angle can not be too small so as not to affect the screening precision. In general, the vibration motor angle of the vibrating screen is 45 degrees when leaves the factory.
Users can also change the vibration motor angle to 100 degrees according to the the special requirements of the material ,and then material will be concentrated to the central screen mesh. 

How to choose the suitable vibration motor for the vibration machine?

Vibration motor has many types and models with a wide application,it is usually applied with the feeder, vibrating screen combination. The vibration motor is very important in the vibration machine. It directly determines the working efficiency of the vibration machine.The vibration mechanical vibration motor selection steps are as follows:
A.According to the operating requirements, confirm the required vibration of the frequency (r/min) and the amplitude Ym (mm).
Such as the six vibration motor (n=960r /min) can drive the vibration chute, vibration feeder, vibration mill, vibrating screen etc.
B.According to the structure of the vibration machine itself, get the vibration weight G (kg) and calculate the required vibration force Fm (N) .
C.According to the vibration of the operation to get Fm, you can get the model of the vibration motor, please pay attention to the exciting force FH is larger than Fm.
D.Design the overall structure, and calculate the actual vibration parameters, after the calculation, if the vibration motor is too large or too small, motor model should be re-selected.
E.Design of vibration isolation system. 

How to solve problem of damp material blockage occurs in vibrating screen?

Vibrating screen is a kind of high precision and fine powder screening equipment, with the characteristics of low noise, high efficiency, small size and quick screen mesh replacement,it adopts fully enclosed structure which is suitable for particles, powder, liquid, etc. Clients ever said wet material blockage occurred in vibrating screen,here PK Machinery will list some suggestion,hope it is helpful.
1.Increase the excitation force of vibration motor and increase the amplitude.
2.Increase the vibration frequency, please use the high-frequency vibrating screen.
3.Diluted with water to increase the liquidity of material.
4.Replace the screen mesh regularly to avoid damp material blockage.
5.Manual work assisted cleaning up the screen mesh blockage.
6.Equip with cleaning device, such as the brush.
