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.

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.

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.

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

The Tin Powder Screening Problem for Ultrasonic Vibration Sieve

1.The output powder efficiency of ultrasonic vibration sieve is low, there is no finish powder or less after sieving, if this kind of situation appears, we need to check the performance of ultrasonic acoustic, whether it is due to the poor quality, resulting in screen mesh blockage, causing the finished powder cannot be sieved out.
2.Larger and smaller size of tin powder exceed the standard, when confronted with the problem, we first need to check screen mesh of ultrasonic vibration screen, uneven powder size mostly may be due to poor quality of screen mesh, aperture size is not same when manufacturers make the screen mesh, or some parts of screen mesh are damaged after long time use, here it requires us select standard and qualified screen mesh from the regular manufacturers, regular check of screen damage is also required.

3. The oxygen content of tin powder is excessive of the standard, it is mainly because of poor sealing ,which lead to air leakage, it is necessary to ensure good sealing and check whether the sealing ring and other sealing place are qualified or not, vibration sieve rubber sealing ring after long time use, it will occur deformation or a series of problems which results in the increase of oxygen content in tin powder. Therefore, check the sealing ring regularly, especially in the case of high temperature in the summer.
4. Unstable ultrasonic vibration screen will cause the screen mesh heating and screen plugging seriously, before using ultrasonic vibration sieve, please select and set the vibration motor power well, check the equipment adjustment flexibility and check if discharging outlet is smooth or not.

 

For points listed above, you will find the tin screening is a impregnable problem. As a senior research, development and production manufacturer, Henan Pingyuan Mining Machinery Co.,Ltd has devoted to solve all the screening problem, we are sure we will be the best choice, more information please click: www.pkmachinery.com

Little maintenance, big protection

Little maintenance, big protection

Have you ever seen a stainless steel vibration sieve covered with rust? It is easy to become matte if the stainless steel vibration sieve put into use for a long time.Therefor,for user,it is better to know the method to maintain the vibration sieve efficiently.Maybe a little maintenance,can make a big protection.Then the following passage will analyze this knowledge detailed.

The reason why vibration sieve become matte mostly because the airborne corrosion.Use long time exposed to the external environment, it is easy to oxidation.In such an environment condition,in order to prolong the service life of it, it is necessary to carry out the stainless steel surface cleaning maintenance in four aspects.

1.Be careful not to scratch the surface when cleaning

2.Avoid using with bleaching compositions and abrasive cleaning fluid

3.Do not use steel wire ball, grinding stuff cleaning stainless steel surface 

4.Scour the surface with clean water, removing washing liquid
