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.

PK Vibrating Screen Applied in Silicon Carbide Industry.

There are 4 kinds application fields for silicon carbide, which are functional ceramics, high grade refractory material, abrasive material and metallurgical material. The different particle size silicon carbide will be used in different kinds of application field,thus it need different models of vibrating screen.
Silicon carbide powder vibrating screen
For powder silicon carbide vibrating screen separating, it needs ultrasonic vibrating screen. The ultrasonic screen machine is based on normal rotary vibrating screen, adding a ultrasonic generator on screen mesh. The ultrasonic generator emanates mechanical wave, driving the screen mesh do three dimensional movement and ultrasonic vibration as well. The combination of the two movement trajectory can solve many screening problems, such as fine material with high precision, high electrostatic, high adsorptiion, large density, little specific gravity etc. Property, which can greatly improve screening efficiency.
Impurity screening in silicon carbide screening industry
The vibrating screen can achieve separating the silicon carbide into different particle size powder, granulate SIC. One set vibrating screen can includes 4 layers screen mesh, which can separate out 2~5 kinds range end products, besides, these different range particle sizes are very near. The vibrating screen can quickly separate out and clear up the impurity, continuously deslagging. 
In a word, when different silicon carbide particle sizes are required,we can suggest suitable vibrating screenaccordingly, rotary vibrating screen, ultrasonic rotary vibrating screen and gyratory vibrating screen for fine screening; linear vibrating screen and circular vibrating screen for large particle size silicon carbide screening.

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.

How to Solve Mesh Plugging Problem in the Process of Resin Screening

There may occur mesh plugging when customer sieve resin by rotary vibrating screen after using for a period of time,even the screen is fitted with bouncing balls and perforated plates. Here our engineer gives the following suggestion:
1. The motor power is relatively large,you can increase the amplitude of the eccentric block assembly weight , then it can reduce the mesh plugging(The larger amplitude is, the lower blocking probability it will be).
2. The mesh cleaning device of natural rubber material needs to replace to silicone, the bouncing performance will be much better,which can reduce the mesh plugging effectively.

The Application of Vibrating Screen in Food Industry

Vibrating screen is a highly efficient screening machinery used in food industry. It’s mainly used for high precision fine powder and other materials with its advantage of easy operation and fully enclosed structure.

It is also suitable for granular, powder, mucus and other materials screening and filtering classification，Such as powdered sugar, starch, salt, rice flour, milk powder, milk, egg, soy sauce, vinegar, fruit juice, papaya powder, green tea powder, kudzu powder, and potato processing production. Materials mentioned above are used frequently in daily life, vibrating screen will be our best assistant.

Take Starch or rice powder for example, In the first step, we usually remove the impurity of raw materials followed by screening and weighing; The next step includes soaking, coarse grinding, germ separation, fine grinding, screening of starch, protein separation, centrifugal dewatering and thermostatic drying, The last step includes weighing and product packing.

During these steps, we will have great difficulty in processing the food without the screening of vibrating screen. Vibrating screen has the superiority in easily screening fine material, and therefore bring us the food diversification and help to develop the entire food industry rapidly.

True Or False Vibrating Screen

With the rapid growth of economy, vibrating screener market is becoming more and more important, meanwhile, more vibrating screen manufactures emerge as the times require. The products’ quality are uneven of different manufactures. Vibrating screener with superior quality is perfect in workmanship, plate standard and no welding seam blind angle welding seam, etc. There are some of merchants sell seconds at best quality prices who sacrifice customers’ interests for their own benefits.

As far as vibrating screen is concerned, it mainly consists of carbon steel, stainless steel 304 and stainless steel 316L. The carbon steel vibrating screen is appropriate for non-corrosive materials, while stainless steel 304 is commonly used in chemical, food, pharmaceutical industry, etc. The stainless steel 316L is applied in special industry which required for high standard with high cost.

Vibrating screen can be judged through the texture of screen machine. The surface of 304 stainless steel is smooth, toughness, high plasticity, and mechanical strength. But the vibrating screen with poor quality presents unqualified welding, easy oxidation, and thus cut down the overall quality. Therefore, the users must choose formal manufacturers through careful identification .

In addition, Users are supposed to get ready for the products inspection selecting products with high quality, safety performance, and great strength. Taking the price of the products into consideration. After all, “Different quality ,different price.” Never chose the inferior products for cheap price.

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.

Why Circular Vibrating Screen can not Start up and Amplitude is Small ?

Days ago,my Russian friend asked me why circular vibrating screen could not start up,however,the amplitude was quite small even if it start up,and the screening efficiency is quite bad,here I summarize the reasons as follows:
1.The circular vibrating screen motor breaks down,please replace the motor;
2.The electrical equipment control circuit fails,please maintain and replace the electrical equipment;
3.The voltage is low,you can alter the power supply;
4.There are many accumulation materials on the surface,please clean up the material;
5.The screen itself has fault,please check and maintain the vibrating screen;
6.The lubricating oil is over thick or caking,please clean the screen and add new lubricating oil;
7.You can also add balance weight to increase the amplitude.
Besides,please also note that the adjustment of vibration source on vibrating screen(exciter or vibrating motor) must be same,or it will cause equipment damage.

Strict Inspection—Provide Perfect Equipment for Cients（Ⅱ）

3.Thickness test of paint coating.
Adhere the coating thickness meter probe to the equipment surface,then the data is the coating thickness of this point.Since the equipment surface area is large,it should be tested with many areas, it also requires multiple measurements to take average.
4.Amplitude test of equipment
After equipment runs normally,adhere the amplitude measuring scale to the side wall of screen box.There are many different circles with different diameter,and the movement locus will become to ellipse due to vibration,however, circles’ movement locus is still a circle,it shows that this circle’s diameter is very approached to the equipment amplitude,therefore,the circle diameter is vibrating amplitude.
All tests above have their own standard data,when the testing data has big difference with standard data,we will debug repeatedly to ensure equipment with a optimum working condition.

Strict Inspection—Provide Perfect Equipment for Clients(Ⅰ)

After the circular vibrating screen production was completed,and there is an important step before delivery goods,that’s test running,and judge the equipment whether can work normally through equipment running condition,please see following test items:
1.Measuring rotary speed of principal shaft
The test principle is through infrared sensor scanning a fixed point on the shaft to confirm the rotary speed.Firstly,pasting the measured speed tags on rotor surface.then running the equipment,after the normal running，let the tachometer probe aims at one point on the tag movement locus,record the data,and it requires multiple measurements to take average.
2.Noise test of equipment running.
A good equipment should work without abnormal sound,after the equipment running normally,place the noise meter probe near the running parts of vibrating screen,record the data, it requires multiple measurements to take average.

What reasons lead to linear vibrating screen motor base crack ?

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.

1.Vibrating feeder is used for batching and quantitative feeding material to ensure uniform feeding stability,horizontal installation should be adopted to prevent self flowing, declined10 degree installation should be adopted if there is continuous feeding, declined 15 degree installation can be adopted for viscous material and large water content material.
2 .After the installation, 20mm level lateral clearance should be left for vibrating feeder, suspension device should adopt flexible joint.
3. Before non-load test, please fix all bolts, especially the anchor bolt of vibration motor tighten the bolts again after continuous operation for 3-5 hours.
4. Two vibration motor must be reverse rotation when test run to check the current and noise stability, if any abnormal conditions, please stop the feeder and solve it timely.
5 Motor bearings should be lubricated every two month, for high temperature season bearings should fill the lubricating oil every month.

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.

Maize can not be sieved without vibrating screen

 Vibrating screen should be adopted in the beginning of the removal of impurities during the production of maize starch,in order to ensure a safe production of raw materials,so the removal of impurities is very necessary, maize raw materials contain a variety of impurities, dust, organic impurities, inorganic impurities. The general design will be 3 screen decks, the first deck screen surface with an aperturesize of 17-20mm hole, aimed to eliminate over sized impurity; second deck screen surface with an aperturesize of 12-15mm hole, used to remove impurities of medium size, third deck screen surface with an aperturesize of 2mm hole, used to remove minor impurities.

It is very suitable for the screening and classification of powdery and granular materials, applicable to dry powder material chemical industry, food, medicine, metallurgy, plastics, glass, building materials, food, fertilizer, abrasives, ceramics etc.

How many types of vibration screen sieve mesh do you know?

Vibration screen sieve mesh is one of the main components of vibrating screen. If the sievemesh can not be chosen correctly, it will even affect the screening efficiency, when screening material is unqualified ( mesh is over sized), materials will accumulatedon the sieve badly (mesh is too small, material will accumulate on the sieve and lead to screen mesh damages). Here we’d like to introduce the different types of sieve meshed as below:
Woven mesh: material commonly used forscreening equipment with smallmaterial density and capacity. The construction materials are stainless steel sieve mesh, low carbon wire mesh, galvanized wire mesh. According to the material particle size, density, volume, material characteristics ,please choose sieve mesh with different construction material, aperture, wire diameter.

Punched sieve mesh: the span life of punched mesh is related to the mesh thickness, different mesh sieve size should use different thickness. The advantage of punched mesh is that it can be fixed according to the material shape.

Welding sieve plate: mainly used for ore sieving, coal sieving, it is welded by steel plates.

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.
