Ultrasonic Vibrating Screen Used for Battery Powder Industry Separation

Battery powder is a battery containing magnetic metals such as lead, nickel, lithium and magnet properties of non-metallic materials. During the treatment of the entire process , vibrating screen plays an important role, we often choose ultrasonic vibrating screen because the separation material belongs to powder material.
Compared with ordinary rotary vibrating screen , ultrasonic vibrating screen is equipped with an extra ultrasonic system, which allow the ultra fine powder can accept the huge acceleration of ultrasound, it can solve adhesion, friction and blockage in the screening of ultra fine powder when using the common rotary vibrating screen and improve the screening efficiency and net cleaning efficiency.
Security is very important in screening because these materials are presented with a certain degree of magnetism and electrical conductivity, these items belong to the secondary water lighted objects,besides as material is slender and easy to float in the air, under the influence of moisture in the air,it will produce hydrogen, which is flammable once it is in the fire,the instantaneous explosion will occur,thus the ultrasonic vibrating system requires a explosion-proof motor.

The Price of Vibrating Screen in Xinxiang

With the rapid development of economy, vibrating screen equipment has already took the place of manual screening. There are lots of questions when it comes to buy a set of vibrating screen for the first time. Generally speaking, the price is what we care about primarily and it can’t not simply determined by its quality. There are other issues we must take into consideration when buying the oscillating screen.

• Price Fluctuation of Raw Materials: the raw materials of shaking screen is steel plate, steel prices’ fluctuation take an effect of the whole machinery. Thus, the selection of different raw materials will bring to different cost. This is the reason why the the same type of vibrating screens have different price.
• Technology: the processing technology of the vibrating screen takes an crucial part of its quality. Keep the manufacture technology from the parts processing to the overall design under strict supervision would guarantee screening classification efficiency.
• Material: vibrating screen can be made into two different types with carbon steel and stainless steel with the latter cost is relatively high.
• Model: the model of vibrating screen is usually divided on the basis of its diameter and the length of cylinder. There are two different categories , light and heavy vibrating screener. Each sieve machine has been made both from different raw materials and technology. This is why the same type of vibrating screeners have different price.

Henan Pingyuan Mining Machinery Co., Ltd reminds you warmly that vibrating screen selection must in accordance with your present situation. Don’t be confused by the so-called vibrating sieve price.

The Requirement of Linear Vibrating Screen in Pharmaceutical Industry

As we all know, pharmaceutical industry has strict requirement for hygiene of various equipment,so we must choose stainless steel 304 or 316 for linear vibrating screen. The contact material part can not appear stain and impurities ,the rubber accessories must reach medicine food hygiene standards as well.
In fact, the linear vibrating screen structure is simple, the so-called standard refers to construction material, it must be 304 stainless steel, and must be the pharmaceutical grade in the selection of sealing, linear vibrating screen needs to be washed carefully for several times by alcohol, and it needs polishing treatment to keep it clean and smooth.

How to Select and Install Screen Cloth of Linear Vibrating Screen

The selection and installation of screen cloth is very important for linear vibrating screen. Select the most suitable screen cloth and install it according to correct way can improve the performance and prolong the service life of the linear vibrating screen.
1. How to select the most suitable screen cloth?
a. Because it is complicated for screen cloth installation of linear vibrating screen, we should select the screen cloth with thicker wire diameter.
b. While cutting screen cloth, we should keep the width of screen cloth consistent with the mesh frame, length should be 50-70mm longer than mesh frame.
2. How to install the screen cloth of linear vibrating screen?
a. Since the tensity of screen cloth will affect the screen efficiency directly, we should keep the screen cloth tension during installing the screen cloth.
b. Please confirm whether needs to add the bouncing balls according to mesh size and difficulty level of the screened material.
c. We should add suitable supported mesh size under the screen cloth if the mesh of the screen cloth is high or bulk density of the material is big.
d. While install the pressing plate, we should keep the flatness of the plate and line with strong scalability sponge sealing to lock it uniformly.
e. After completing installation, we should test the condition of feeding material and screening with few materials. If materials run forward uniformly, classify accurately without mixing phenomenon,linear vibrating screen can be used well. If not, we should adjust the linear vibrating screen mesh and test again.

Reasons lead to circular vibrating screen mesh plug

When circular vibrating screen works, the material properties are very different, as well as its shape. Due to different shape of material ,it can produce a various forms of mesh plug.After the analysis of PK machinery engineers, the cause of mesh plug mainly shown as follows:
1.Contains a lot of close to the separation point particles
2. The material moisture content is higher
3. The spherical particles or material has multi-contact points property to mesh 
4. Static electricity occurs
5. Material is a fibrous material
6. Flake shape material proportion is more
7. Woven mesh wire diameter is too thick
8.Thick Sieve mesh, unreasonable hole shape design, which will lead particles get stuck.

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.

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. 

How to Make Vibrating Screen Look Clean without Stainless Steel?

Stainless steel vibrating screen will become matt if they are used for a long time, when screening materials with chemical reactions (such as corrosion) ,there would be a passivation film on the surface, it will exist steadily as a shape of the oxide in the nature. In other words, though stainless steel working conditions and oxidation are not the same, they will be oxidized in the end, this phenomenon is often called corrosion. The metal which is exposed in the corrosive environment, it will produce electro-chemical or chemical reaction on the surface of metal, even corrode. Corrosion resistance abilities of vibrating sieve passivation film are weak, due to stress caused by pitting corrosion reactions, it will generate small holes, coupled with the approach of chloridion, it will form a strong corrosive solution, which will accelerate the corrosion reaction rate, as well as the corrosion cracking inside the vibrating sieve, all of these will have a destructive effect on the surface of the stainless steel vibrating screen .
Therefore, stainless steel surface needs cleaning and maintenance punctually, especially in the corrosive environment to ensure its beautiful surface and extend the use life. It is necessary to pay more attention to not scratch the surface during cleaning, and please avoid cleaning the surface by using liquid bleaching composition or abrasives, steel wool and abrasive stuff, in order to clean up the washing liquid, please clean it with water again after finishing scrubbing the surface.
