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.

The Reasons for Vibrating Screen Material Accumulation

The Reasons for Vibrating Screen Material Accumulation

During use, the vibrating screen surface may occurs the material accumulation phenomenon. So what causes the accumulation of material is it, here PK Machinery engineer based on years of experience in analysis of what can be attributed to four issues:
1.Make sure whether the vibrating screen mesh choice has problems or not, sieve mesh network is too small will cause low permeability material.
2.Check the placement of vibrating screen ground whether is flat, spout material will affect the operation of high trajectory, causing the material to one side.

3.Screen mesh and the discharge port whether is horizontal or is too high, under normal circumstances should be level or higher than about 6mm, depending on the material discharge port design are not the same height.
4.Vibration motor angular adjustment if there are problems, improperly adjusted 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 so that bulk material outward open 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.

How to Install the Circular Vibrating Screen Punching Mesh?

Screen meshes Includes manganese steel woven mesh screen, perforated plate, stainless steel sieve, etc., each of which has its own special place, and therefore it should be selected according to the actual situation.Here we will share some of the easy to implement tips to install the circular vibrating screen punching mesh.
Vibrating mesh sieve punching method of installation with slime mesh sieve dehydration installation is similar. Entire slime dewatering screen is horizontal assembled, but in order to ensure the dehydration effect of the machine, so the screen is negatively corner installation. Alternatively polyurethane screen mesh, tension mounted, or stainless steel weld seam sieve, pressing installation, to meet different needs. But the circular vibrating screen is angled, when using perforated screen, pressing need for the use of square wood, wedge tensioning way.

Insufficient tightness of the screen will cause the following effects:
① mesh bending deformation, stress concentration serious, relaxation is easy to produce secondary vibration sieve, sieve premature breakage under alternating stress, caused no small economic loss;
② bending deformation affecting mesh sieve through effective screening area, so this should be through the sieve through the sieve material failed, resulting in reduced screening efficiency;
③ screen surface depressions lead to material retention, hinder the forward movement of the material layer, and ultimately affect the productivity of the shaker.

In view of this, increasing the tension of the screen, to ensure smooth screen surface, not only can effectively improve screen life, but also help to ensure the efficiency and productivity of vibrating sieve.

Why vibration sieve screen mesh damaged so fast?

Why vibration sieve screen mesh damaged so fast? Factors that quicken vibration sieve screen mesh damage are like screen mesh quality, screen mesh tensioning force, material feeding problems etc.In numerous factors,screen mesh quality is the key factors that aroused screen mesh damaged fast.Here we will introduce the each factor as follows.
vibrating screen mesh
Factors:
1.Screen mesh quality is an important factor that aroused screen mesh damaged fast. If the screen mesh material can’t meet with the requirement of the material sieve, then the screen mesh will damaged soon.
2.Screen mesh don’t have enough tension that caused the screen vibrate, in this case the screen mesh usually damaged or broken along the edging.
3.Generally speaking, screen mesh has an upper and a lower force layer, which request that the two layers contact closely. If the screen mesh pre-tensioning is poor, when the lower force layer is tension but the screen layer isn’t tension, then when the vibration sieve working the vibrating distance of the screen mesh is too long, can’t effective compress with the screen frame contact section, these is also one reason that aroused screen mesh damaged so fast.

4.Material feeding problem As we should keep feeding during the vibration sieve work process, if feeding too much one time will block the material normal movement on the screen plate, which not only easily make the screen mesh become loose but also will greatly reduce the capacity of the material. Feeding material too much one time will make the unbalanced motor loading suddenly increased, which not only easily damaged screen mesh but also easily caused the vibration motor damaged, so when we feeding material must feeding uniformity. If the feeding way has strong impact, the vibration sieve must equip with impact hopper. If the material impact the screen mesh will consume exciting force generated by the vibration source, which more likely to cause screen mesh damage and screen mesh fatigue.
screen mesh
Solutions:
1.When you choose the vibration sieve you should choose the quality reliable screen mesh
2.Check the tensioning force of the screen mesh usually
3.Check whether the screen mesh squeezing ramming or not
4.If you sieve liquid with strong impact, you’d better equip hopper or buffer.
5.If there is accumulation of material, you should find out the reason as soon as possible such as adjust the eccentric of vibration motor

Is The Driven Device Suitable For Linear Vibrating Screen?

Linear vibrating screen is designed with dual-vibration motor drive.According to the capacity of different material is different, the vibrating screen model and the vibration source is different also.Here PK Machinery would like to talk about the driven device selection for linear vibrating screen.
For some ceramics, food, and other less dense granular material, when dealing with a smaller amount, demand shaker model is small, usually less than the length of the screen surface 3000mm, width of the screen surface is less than equal to 1200mm, the small screen of its own weight , to meet the amount of processing conditions, the vibration source shaker select both synchronous and opposite vibration exciting force generated by the motor rotation direction. The motor can be installed on top of the screen box, bottom and sides.


Linear Vibrating Screen

For some coal, ore, building materials and other denser particulate material is too large, the environmental conditions, the general requirements of larger handling capacity, demand shaker models are also relatively large, usually larger than the screen surface length 3600mm, when the screen surface is greater than the width of 1500mm, the weight of the screen itself is also heavier. When the amount of processing required to achieve, you need to select running motor driven exciter excitation force generated as the vibration source, achieve grade materials. Exciter is usually installed above or below the screen box.
If conditions have space restrictions or special requirements, we also can make special optimized design.

So What is the Right Way to Operate the Linear Vibrating Screen?

What should we notice when use linear vibrating screen for the first time?Maybe you should be pay attention to  the following six points.
1.Check if there is bolt looseness of the linear vibrating screen.
2.Remove four fixed plates of all the springs on the linear vibrating screen in order to protect the machine from scratch during transportation process.
3.Read the manual carefully and check the components before testing the linear vibrating screen.
4.Since vibration motor works continuously, it needs to be filled with oil regularly .
5.Check if there is screen mesh damage when the machine stops working.
6.As some users may choose wood net rack, please also check if there is screen frame damage. Compared with steel net rack, the wood net rack is easy to replace screen mesh,however, the life span is much shorter.
