Vibro screens are one of the most versatile, reliable and economical continuous process equipment for carrying out various size based separation like screening, sifting, classification, grading, oversize or undersizes removal, de-dusting, de-watering, de-lumping, fiber recovery, filtration, pre-filtration and scalping.
Vibro screens are vibratory or gyratory sieving machine designed on the principle of gyratory motion generated by vibratory motor. The machine performs any size based separation with the use of wire mesh or perforated sheet and can work for various application of solid separation or solid liquid separation or slurry separation.
Vibro screens are mostly known as “vibroscreen” or “gyro screen” but also sometimes known by the names screening machine, screener, vibrator, sifter, grader, classifier, separator, sorter or filter.

Whether your application is small, large, straightforward or problematic, Techno can produce it with unequalled cost effectiveness.

Vibro Screens are designed to perform effective size based separation in coarse as well as fine sizes. Vibro Screens use wire mesh or perforated or slotted sheets for carrying out separation of material on basis of size. Vibro Screens are designed on the principle of Gyratory Motion and are one of the most versatile and universally adaptable machines working across spectrum of industries.
Vibro Screens can carry out various duties including screening of any powder or granules, sifting and grading or classification, removal of oversize/ foreign material before packing your finished product, lump/ undersizes/ chips/ dust removal from powder/ granules, solid liquid separation/ filtration/ grit (ungrounded Material) removal from slurry, syrup or oils, fiber / husk recovery from liquid stream.
Vibro Screens are used by Industries like Agro, Agro Processing, Ceramic, Chemical, China Clay, Dehydrated Food, Dyes and Pigments, Ferro Alloys, Foundry, Engineering, Food, Mines and Mineral, Metal Powder Processing, Plastic, PVC, Petrochemical, Paper, Roto Molding and many more.
Vibro Screens are very versatile process equipment and provide reliable and economical solutions for spectrum of size based separation operations performed in most of the industry sector / applications due to its flexibility and distinctive advantages. Vibro Screens are your best bet for performing the operation of Classification, Grading, Oversize/undersizes Removal, De-dusting, De-watering, De-lumping, Fiber Recovery, Fiber Separation, Continuous Filtration or any type of size based separation.

Construction and Function of Vibro Screen (gyro screen)

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 adjust-ability 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.

Anti Vibration Mounts

Isolates the machine vibrations of machine from the ground. It also helps in accurate leveling of the machine.
Lift the machine from the floor and install on DISC MOUNT, Screw down the bolts into their respective guides . By tightening bolt Leveling guide will rise from ground level along with machine.Thus you Level the machine. After leveling the machine, start the machine. Machine will generate shock / vibrations, this vibration will pass to the rubber of disc mount, and rubber will absorbs shock / vibration without transmitting them to the floor.

Feeder Hopper with Vibro Screen (gyro screen):

This device helps you to ensure continuous and steady feed to the machine. Very useful where feed material is to be manually dumped from bags.

Mesh Fixing Fixture For Vibro Screen (gyro screen)

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.

Ball Tray / Ring Tray for Vibro Screen (gyro screen)

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.
