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.

Vibrating sieve surface material buildup reasons

In our company, there will be individual customers often call me to ask some information today explained one: Vibrating screens will appear in the course of the screen surface has a material accumulation phenomenon. So what is causing this phenomenon is the reason? Pingyuan mining mechanical engineer for detailed analysis of the phenomenon based on years of experience, can be attributed to four reasons:
1, the screen and the discharge port are in the same height? Under normal circumstances should be level or higher than about 6mm, depending on the material discharge port design are not the same height.
2, mesh shaker screen of choice if there are problems? Mesh mesh screen is too small will cause the material through network rate.
3, shaker vibration motor angle adjusting Is there a problem? Improper adjustment of the angle of the vibration motor can also cause material accumulation phenomenon, the smaller the angle on the screen surface material spread outward run faster, whereas angular displacement of the General Assembly to make the material spread out slow. If you are under strict requirements for screening accuracy, the motor angle should not be too small, so as not to affect the accuracy of screening, in general, the factory motor shaker angle of 45 °, the user can also special screening process based on its material Requirements will adjust the vibration motor angle to 100 °, the mesh material is centralized.
4. Check if the shaker is placed on the ground level, high spout will affect the operation of track material, causing the material to one side.

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.

Installation notice of circular vibrating screen punching mesh

General screen meshes include manganese steel woven wire mesh, punching mesh and stainless steel screen plate etc. Each kind mesh should be selected according to the on-site working condition. Today we will talk about the installation of punching screen mesh.
The punching screen mesh installation method for circular vibrating screen is the same with dewatering screen. 
Generally speaking, the slurry dewatering screen is horizontally installed,however, in order to guarantee the application effect, the screen mesh is installed with a negative angle. The screen mesh can be polyurethane material with tension type installation, or stainless steel bar screen mesh with compression type to meet different working conditions.

Circular vibrating screen is installed with angle, when adopt the punching screen mesh, it needs lumps of wood to press tightly, then tension with wood key . Please see the following sketch: 
If the screen mesh tension is not enough, it will bring negative influence:
1.The screen mesh is easy to bend and the screen mesh will slack and easy to revibrate. Meanwhile it will reduce the screen mesh service life. 
2.It will influence the effective screen surface, reduce the screening efficiency.
3.It will stop the material moving forward and reduce the capacity.
In this regard,in order to guarantee the smooth screen mesh , increase the service life and guarantee the capacity and screening efficiency, the tension of screen mesh must be improved.
