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.

Instruction of Trommel Screen

Trommel screen is composed of motor, reduction unit, cylindrical drum, screen frame and sealing cover. Cylindrical drum screen is normally elevated at an angle at the feed end.Classify

      1. Functions: configured for classification, screening, grading
      2. Type: open type, closed type
      3. Classification: shaft rotary screen, shaftless rotary screen
      4. Construction: carbon steel, stainless steel
      5.Applications Scope: widely used in chemical, coal, construction, gold mine, plastic,quarry,recycling, metallurgy, mineral-selecting industries, etc.

trommel screen

► Working principle
When material flow towards along the inclined rotating drum,materials jump and roll , the undersized material smaller than the screen apertures passes through the screen wire mesh, while the oversized material passes out at the other end of the drum.
► Advanage

    1.Steady and smooth operation.

    2.Low noise and low energy consumption.

    3.Simple structure with easy maintenance.

    4.Suitable to separate various materials especially poor quality of coal and coal slime.

    5.Equipment is fully sealed with cover in order to minimize the suspension of fine materials in the air during the operation. Low dust pollution.

    6.High screening efficiency due to installation of comb shape screen structure.

    7.Cylindrical shape of the screen provides larger surface area for the materials to in contact with. Able to handle large capacity of materials with high efficiency.

    8.Long life span.

► Features
    1.Smooth operation, low noise,low energy consumption
    2.Simple structure, convenient maintenance
    3.Trommel screen sieve can be sealed designed, no dust pollution
    4.Special screen mesh design, high screening efficiency, longer service life, less blockage

drum screen

► Application
Trommel screen sieve is applied to compost, chemical, coal, construction, gold mine, plastic, recycling,metallurgy,mineral-selecting,agriculture etc.
