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.

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 Helpful installation tips of vibrating feeders?

Vibrating feeder is generally used for evenly, regularly feeding, distributing bulk material in different production lines to guarantee the steady connecting between the upper and bottom equipment. When feeder model is small with little capacity, the drive device can be 2 sets vibrating moor; while the feeder model is large with heavy capacity, the driven device can be 2 sets motor and vibrating exciter. It will be selected according to the actual technical requirements. 
In addition, vibrating feeder can be designed to be seated type or hanging type according to the on-site working condition and installation space. 
When vibrating feeder is installed under the hopper or silo outlet, and there is no enough or suitable installation foundation for vibrating feeder, it can be hanged with hanging devices to save the installation space,which makes the equipment connecting more easier. 
If the customers require seated type,vibrating feeder should be installed on embedded foundation.
If the material size is very small,similar like powder, dust etc. The vibrating feeder can be enclosed with dust hole and connect the dust collector in system to protect the environment. 
If any special requirements, vibrating feeder can be customized to meet the special technical requirements.

► Introduction and working principle：
Rotary vibrating screen is designed as a high-precision screening machinery. Round vibrating sieve is composed of vertical motor,and eccentric weight installed at two ends.We can produce horizontal, vertical, inclined motions by adjusting the upper and lower eccentric weight.Diameter can be ranged from 400mm to 2000mm, with single or multiple screening decks.
► Working Principle：

XZ Rotary Vibrating Screen is a vertical-motor system, with eccentric hammers being installed on top and bottom of the machine, where the motor acts as the vibratory source. The direction of the eccentric hammers may change its rotational mode either in horizontal, vertical and inclined movement onto the sieving screener surface. The trajectories of the materials on the sieving machine can be change by adjusting the phase angle on both top and bottom parts.

Introduction of Circular Vibrating Screen

Circular Vibrating Screen is a kind of new and highly effective vibrating screen that does circular vibrations and has multiple layers. Circular vibrating screen adopts cylinder postures eccentric block to produce strong exciting force. Its main body is connected by high strength screw bolts. A circular, elliptical vibration motion is created in order to sieve the materials efficiently. It is composed of screen box, screen mesh cloth, suspension (or support) device, underframe and motor.

► Working principle
Circular vibrating screen separator uses eccentric block(YK type)/eccentric shaft(YA type) to produce strong exciting force, due to the unbalanced centrifugal force of inertia of the weights on the exciter, screen box vibrates, it can obtain different amplitudes by changing the exciter eccentric weight.
