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.

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.

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 ?

All users know that the vibration motor is the vibration source of linear vibrating screen , it will bring inconvenience of operation if the vibration motor base cracks and damages. Here are some analysis reasons for you:
1. Too large motor power ,model selection and exciting force which exceed the normal load of vibrating screen, it will cause damage of motor base for long time operation
2. Too thin steel plate thickness design with long time operation will cause crack.
3. There is a problem with steel plate material.
4. Welding quality can not meet the requirements.
5. The installation position of the motor does not conform to the design requirements of the vibration dynamic specifications.

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.

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.

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.

Do not Ignore the Unbalance Motor Vibration Phenomenon of Vibration Table!

Vibration motor is not as what you imagine, only plus a few springs on the equipment, and put on a few motors, it will become a veritable vibration equipment, then will be used for vibration production? In fact, sometimes the question is much more serious than the imagination, the theory and practice is the only way which can reach truth. Next Henan Pingyuan Mining Machinery Co., Ltd will explain to you: The unbalance vibration phenomenon of the vibration motor for vibration table.

The problem of vibration which cannot meet the vibration motor in the running of the equipment, also can never be solved, that is uneven and unbalance of the vibration. The influence of the unbalanced vibration in the screening equipment is less, while the influence will often appear in making the vibration table. However in the reality, the unbalanced force of vibration equipment is often neglected by us.
1. In the use of a single vibration motor on the vibration table, it can appear the problem of motor rotation, the material will move on the surface of vibration table.
2. In the use two vibrating motors, it will change the uniform vibration point of the vibration table. Due to counter rotation of two motors , it will offset the power in the middle of the vibration table. If the vibration amplitude around the platform is 5mm, the vibration amplitude in the center of the table can't be over 3mm.
