The Reasons for Vibrating Screen Material Accumulation

The Reasons for Vibrating Screen Material Accumulation

During use, the vibrating screen surface may occurs the material accumulation phenomenon. So what causes the accumulation of material is it, here PK Machinery engineer based on years of experience in analysis of what can be attributed to four issues:
1.Make sure whether the vibrating screen mesh choice has problems or not, sieve mesh network is too small will cause low permeability material.
2.Check the placement of vibrating screen ground whether is flat, spout material will affect the operation of high trajectory, causing the material to one side.

3.Screen mesh and the discharge port whether is horizontal or is too high, under normal circumstances should be level or higher than about 6mm, depending on the material discharge port design are not the same height.
4.Vibration motor angular adjustment if there are problems, improperly adjusted the angle of the vibration motor can also cause material accumulation phenomenon, the smaller the angle on the screen surface material spread outward run faster, whereas angular displacement of the General Assembly so that bulk material outward open slow. If you are under strict requirements for screening accuracy, the motor angle should not be too small, so as not to affect the accuracy of screening, in general, the factory motor shaker angle of 45 °, the user can also special screening process based on its material requirements will adjust the vibration motor angle to 100 °, the mesh material is centralized.

Methods to Improve the Screening Efficiency of Vibrating Screen

For different ‪‎screening materials,the screening efficiency may different.In order to better sieving the materials,it is necessary to improve the screening efficiency of vibrating screen.Here,PK Machinery lists the methods which can really improve the sieving efficiency as follows.

vibrating screen

First of all,we will show you the two mainly tips.One is dry sieving,and the other is wet sieving.
For dry sieving, you should strictly control the feed water, when the water is high, then considering the screening ingredients.
For wet sieving,conditions permitting, this is the most effective means to improve the screening effect.

Then secondly,the following methods you also should pay attention to:
1.Selection with self-cleaning sieve sieve batter to reduce porosity, such as adding anti-clogging means spring rod sieve or screen below
2.Improve the sieve openings, high aperture ratio will help to improve the screening effect
3.When feeding, feeding along the full width of the screen to make full use of the screen surface
4.Reclining screening machine if conditions permit, the appropriate angle helps to reduce the material thickness, to achieve a thin layer of screening material
5.Counterweight adjustment method to improve the circular vibrating sieve effect

The Advantages of GTS Drum Screen

 Here PK Machinery would like to introduce the advantages of GTS drum screen :
1. wide application and adaptability
2. material feeding method is simple and varied
3. high screening efficiency ,it can be equipped with comb type cleaning structure
4. large screening capacity, easy to be large-scale
5. small energy consumption, long service life, less maintenance
6. low noise, good working environment

GTS drum screen structure: the main structure of drum screen is the sieving drum, which is inclined, the external drum is sealed by a sealing cover to prevent environmental pollution.
Drum screen can be equipped with comb clearing structure, in the process of screening ,the comb cleaning and the drum screen do relative movement to achieve the continuous screening purpose which will make drum screen clean and keep it from sticky, blockage and not not affect the sieving effect.

Gyratory Screen used for Tea was Delivered to India

On September 11th, 2015, one set gyratory screen ordered by our Indian customer was delivered from Qingdao Port. This kind of machine is used to screen tea and its capacity is 100-150kg/h. According to our customer’s requirements, the engineer selected model 5PXZS1236 to meet the needs.

 

Gyratory screen has 5 layers and the size of screen of every layer is 8 mesh, 10 mesh, 12 mesh, 16 mesh, 20 mesh respectively. So this type can meet customer’s demand well. Actually, this business can realize our mutual benefit.

 

In addition, PK Machinery has abundant experience in doing business with foreign customers and exporting vibrating screen, belt conveyor, bucket elevator, scraper conveyor and screw conveyor for many years. We anticipate your enquiry sincerely.

Dewatering Screen for coal industry

Dewatering screens have a wide variety of application including dewatering, desliming, degritting, rinsing, scrubbing and washing. It is made up of screen cloth, vibration exciter, supporting system and motor. Materials such as sand, gravel, crushed aggregates, frac sand, industrial sands, mineral sands, hard rock, precious metals, coal, iron ore, salt and other granular materials which can be processed through a dewatering screen.

Working principle:

      To dewater material effectively, damp material is feed onto a steep, downward inclined screen surface at the feed end of the Dewatering Screen to achieve rapid drainage. A pool of water begins to form in the valley as material builds up on the slightly upward inclined surface. Counter rotating motors create a linear motion, driving solids uphill, while liquid drains through the screen media. The uphill slope of the screen, along with a discharge weir, creates a deep bed that acts as a filter medium, allowing retention of material much finer than the screen openings.
      When the two vibrating motor that installed vertically on the coal dewatering screen rotate relatively, the eccentric block of two vibrating motors produce rated excitation force. The horizontal excitation force cancel each other out, the vertical excitation force is transported to the whole screen surface through the body mass vibration.

Features:
   1. Low noise, easy to maintain
   2. Large capacity
   3. High screening efficiency
   4. Light weight, easy to disassemble and replace
   5. Stable structure and strong exciting force

Advantage:

   1.Stable structure with strong exciting force
   2.High screening efficiency and low noise pollution created
   3.Durable and easy maintenance
   4.Materials that stuck at the screening mesh can easily remove
   5.Low energy consumption
   6.Large handling capacity.
   7.Light weight, easy to disassemble and replace

Application:
Dewatering screen is widely used in coal industry, ore industry, electricity industry metallurgy industry, mining industry etc.

The Development Trend of Vibrating Screen

Vibrating screen is widely used in mining, coal, smelting, building material, refractory material, light chemical, medicine, food etc..

With the higher and higher requirements, the development of vibrating screen reaches a new stage. Combining the domestic and abroad situation, it can be divided into some aspects as follows:
1.To develop in the direction of high efficiency and large output 
Development of industrial modernization process which increases enterprise scale and production capacity greatly, so it needs to match with an efficient high-throughput screening machine.
2.To develop in the direction of standardization, serialization and generalization 
This is a good way to guarantee the quality and reduce the cost , it also provides convenience for designing and organizing specialized production.

3.To develop in the direction of stronger vibration strength
The vibration of vibrating screen is strengthened gradually in order to improve productivity and screening efficiency.
4.To develop in the direction of light ,environmental protection and simply structure
Now the structure of vibrating screen is much more simple than previous one, it is more convenient to replace the screen mesh and will save a lot of time.
