Vibro separators are circular gyratory screens used to separate solids from solids and liquid from solid. Vibro Sifter consists of Specially Designed Motor mounted vertically at the center of the base plate of the Screen. The Screen is in between feeding hopper and bowl. The material is fed on to the centre of top screen. The undersize material passes rapidly through the screen during its travel to the periphery. The over size material get continuously discharged through a tangential outlet. This is achieved by specially designed Vibratory Motor along with eccentric Top and Bottom Weights.

Working Principle:

The top weight on the motor shaft rotates in a plane close to the centre of the mass of assembly. Rotation of the top eccentric weights creates vibration in the horizontal plane which causes material to move across the screen cloth to periphery increasing the horizontal throw, causing oversize material to discharge at a faster rate.

The bottom eccentric weight rotates below the centre of mass creating tilt on the screen giving vibration in vertical and tangential plane. Increasing the vertical component of motion, this promotes turn over of material on the screen surface helping maximum quantity of undersize material to pass through the screen. Rugged Springs placed over the circular motor base amplifies the vibration

Special Features of Vibro Sifter :

  • Faster Separation due to springs
  • Multi deck models available
  • Same sieve as used in Mechanical sifter.
  • Lesser Maintenance and Power Consumption than the
  • Conventional Sifter.
  • Simple & Compact construction.


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/ undersize/ chips/ dust removal from powder/ granules, solid liquid separation/ filtration/ grit (Un-Ground Material) removal from slurry, syrup or oils, fiber / husk recovery from liquid stream.

Vibro Screens are used by Industries like Pharmaceuticals, 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, Rotomolding and many more.

Vibro Screens are very versatile process equipments 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/undersize Removal, De-dusting, De-watering, De-lumping, Fiber Recovery, Fibre Separation, Continuous Filtration or any type of SIZE based separation.


Vibro screen is a generic product and specializes in Vibro screens, but offers Vibro screens for immense variety of applications and configurations. Depending on the specific function it is assigned to do, Vibro screens are also differently known as Vibro, Gyro, Gyro Screen, Sieve, Siever, Sifter, Separator, Screener, Filter, Pre-Filter or in some industry as Grader, Classifier etc. However to meet various customer needs and duties, Offers Vibro screens in various product series with different product specification. To get more details, refer to Models, Configurations and specifications.

Vibro Sifter / Vibro Screen Series SVS-SLX :

Series SVS-SLX is the Standard series meant for most industrial and semi industrial applications in general industry. This is a proven, sturdy and cost effective design in demand by most of the customers. This series is the fastest moving one with most easy availability of components and shortest delivery periods.

Series SVS-SVX :

Series SVS-SVX is the Premium series meant for specialized industrial applications very demanding in nature either by way of operating hygiene, operating environment or sensitivity of material being processed. More details of features can be available on request.

Series SVS-SGX :

Series SVS-SGX is the Special series meant for specific purpose. These one are mainly designed for off line duty or less demanding on-line duty. This type of design is recommended by us on requirements of specific cases.

Series SVS-SSX :

Series SVS-SSX is the Very special series meant for Rare industrial applications requiring high degree of customization with design arrived after various deliberations. For example…

  • Small Batch Siever
  • Soft Lump Breaker


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 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.

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.
