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.

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.

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.

Application & Development of Vibrating Screen in Food Industry

Vibrating screen used in food industry is a kind of high efficiency screening machinery for high precision fine powder and other materials , which is easy to operate, fully enclosed structure, 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 which are commonly used in daily life,vibrating screen will be a good helper. 
Take starch or rice powder as example, usually the first procedures : impurity removal of raw materials - screening-weighing;secondly , soaking- coarse grinding-germ separation-fine grinding-screening of starch-protein separation-centrifugal dewatering- thermostatic drying, lastly,weighing-product packing. We can not imagine how to deal with the screening in the process of food without vibrating screen. Vibrating screen overcomes the difficulty of fine material screening easily, which also makes food diversified and entire food industry develop rapidly.

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.

New dust removal method for vibrating screen

Most of the Dust removal method of supported type vibrating screen in our country is cloth bag dust removing technology, which includes cover dust catcher, pipelines, cloth bag dust collector, induced draft fan and chimney, etc. The advantage is high dust removal efficiency. However,the disadvantage is large investment, low dust collecting rate, easy blockage of horizontal pipeline, large pumping air volume, high operating cost, big occupied area of dust catcher,induced draft fan and chimney, besides, it needs to set up full-time operation& maintenance personneland the dust transport equipment.
In order to solve the above problem, we have researched a new resolution with high rate of dust removal system, low processing cost, long service life, less investment, small area coverage and short construction period.
The new dust removal method offers secondary dust removal for supported type vibrating screen.Primary dust removal equipment will fixed above the vibrating screen,collected dust will enter into vibrating screen; Secondary dust removal equipment will be placed near vibrating screen and remove dust by itself.

Primary dust removal: seal the supported type vibrating sieve surface and set a dust filter above it,set up an efficient filter bag to filter the air, clean air will be discharged through 3.0 kW fan, thus dust will enter into the vibrating screen through the bottom of the filter. Vibrating screen drives sieve surface vibration,while the dust filter is fixed, so one moveswhile the other one not, both connected by the pipe, the joint connection adopts rubber to reduce the vibration.
Secondary dust removal: Seal the supporting type vibrating screen and dust removal joint, leave a open mouth to connect the pipe for conveying the escaped dust into the secondary dust filter,set a high efficient dust filter bag to filter the dust, and then the clean air will be discharged through 3.0 kW fan, then the dust is discharged from the filter at the bottom of the tube and the valve.

What is the applicable material for drum screen?

Drum screen is a kind of cylinder revolving screening machinery that relies on gravity, its working principle is different with rotary vibrating sieve, linear vibrating screen, drum screen can generate strong exciting force, so if dealing with the proportion of lighter materials, it is not suitable for drum screen, the screen is easy to get blocked due to the irregular shape material, and the most important is the screening effect is bad, so what is the applicable material for drum screen?

trommel screen

Drum screen also is often used in mining, sand ,gravel industries, common screen mesh size can be larger than 5 mm, the smallest mesh size should larger than 3 mm, if the mesh size is smaller that is the wire mesh is small ,the service life will be shorter, besides, the drum screen doesn’t do a good job for on sieving fine material and the sieving efficiency is not very good.

 

Except for sandstone, drum screen is also more commonly used for granular material screening, such as: chemical fertilizer, ceramsite and so on. The sieving efficiency is good and easy to handle large-scale capacity.
