Vibro Screen, Manufacturer of Vibro Screens
|
CONSTRUCTION AND FUNCTION :
Vibro Screens are designed on the principle of gyratory motion generated by double eccentric weight mounted on two ends of the shaft of vertically mounted specially designed vibratory motor. The screening assembly consisting of one or more set of Deck/screens is mounted on a set of annularly located springs, effectively isolating the base from vibrating assembly.
The double weight moving with the shafts and located at relative angular position produces three dimensional vibrations which in turn cause the material falling on the screen mesh move at a specific speed in straight to spiral direction giving controlled and effective screening.
Due to the adjustability of weight and the relative angle between them it is possible to make the material move on the screen in desired path to achieve the desired retention time for effective screening before the material gets discharged from the outlet spout. During this process the particles smaller than the mesh aperture fall through the mesh and the oversize material gets discharged from the outlet spout. This process is repeated on the next mesh in case of multi deck screening.
MODELS :
The series SVS-SLX & SeriesS VS-SVX have common models and basic details which are shown below. However, by default, the Vibro screen requirement is understood to be for Series SVS-LX product.

| ATTACHMENT & ACCESSORIES |
Dust Cover :
This accessory is must for dust free screening. It is conical cover with an inlet hole in centre for feeding material and as inspection window to see the screening process on the mesh. Dust cover is clamped on the topmost deck with the help of 'V' grooved and 'C' clamp and can be removed easily if not required. |

Ball Tray / Ring Tray :
This is useful to achieve non clog screening. A tray having rubber /PP balls or rubber / plastic rings is mounted underneath the fine mesh screen. The ball / ring get continuous vibrations from machine and hence they jump and hit the fine mesh from below. This makes particles trapped in the mesh holes to fall down and thereby keep mesh opening as clear as possible. |
|
| |
|
Feed Tray :
This is effective for multiple deck screening and grading application. The material which gets thru the mesh near the outer periphery of the screen gets very less retention time on the next mesh. Feed tray is a reverse conical tray mounted between two decks so as to collect the material falling from upper deck and feed this material in the center of the next screen to give the material maximum retention time. |

Quick Opening Clamps :
This is useful for the applications where frequent opening is necessary due to requirement of cleaning and / or change of batch or color. It is advisable NOT to use this feature if it is not demanded by application. |
|
| |
|
Mesh Fixing Fixture :
A useful accessory incase where mesh is to be tied frequently due to high wear and tear from abrasive or heavy nature of material. It is still advisable to keep a spare screen ring if the mesh change over is to be done fast. |

Feeder Hopper :
This device helps you to ensure continous and steady feed to the machine. Very useful where feed material is to be manually dumped from bags. |
|
| |
|
Anti Vibration Mounts :
Isolates the machine vibrations of machine from the ground. It also helps in accurate leveling of the machine. |
