Applications &Working Principle
PromasTM Vibro Sifter is multi layer screening unit to separate mass composition of solids from solids, liquid from solid and gradation of materials in accordance with their shapes & sizes. Mostly found useful for the applications in pharmaceutical, chemical, food, drug, detergent, etc.
PromasTM Vibro Energy Separator is a rigid screening device that vibrates about its centre of mass. The central vertical axis being the same, vibration is accomplished by placing eccentric weights on the upper and lower ends of the motor shaft. Adjustment of the quantum and relative position of the top and bottom weight permits control of amplitude and material flow patterns.
Circular screen separators are unitized machines, which impart adjustable, multi-plane, mechanical vibrations to the material being processed. The basic assembly shown in the drawing consists of number of interchangeable frames for retention of screen decks & provision of discharge outlets. A motion generator (Vibro Motor) with double extension shaft having eccentric variable weights is rigidly mounted to the main screening assembly. The assembly is supported on the circular base by specially designed springs, which allow the screen assembly to vibrate freely. The controlled vibrations generated by motion generator are isolated completely from heavy structure. The isolation of spring from support base results in a self-balancing system, which requires minimum power & avoids mechanical stress.
Available in various models, named as PVS - 12, 18, 24, 30, 36, 48, 60 to PVS - 72, the numbers denote the diameters of the sieves in inches. It is a compact unit for easy operations with all contact; parts in AISI 316 and all other parts in AISI 304. Springs amplify vibration leading to reduced electrical power & maintenance cost.
The unit can be provided with single deck, double deck or triple deck as per requirements.

Online Agitated Vibro Sifter
The sifter is provided with pneumatic! motorized vibrator & a central discharge. The outlet of the sifter is connected directly to the load cell with digital weighing system. The models are available in GMP/ cGMP/ GAMP/ GLP/ GOP & are ergonomically designed for the ease of operation. The sifter is more versatile for online continuous production.
Turbo Sifter
Product is uniformly fed into the cylindrical sifting chamber by means of a feed screw which discharges into a rotating helical paddle. Turbo Sifters are available in various models.
Unique Features
- All the screens are fixed in circular square sectional frame with "Z" type specially designed sealing
- The mesh is fixed by using jig fixtures, gives maximum tightness to the screen, thus preventing the screen from sagging
- No welding or soldering is used for the screen, it is directly bolted to the frame
- Solid flanges with groove & "0" ring for perfect sealing so as to avoid the leakage of the fine dust
- All the sieve joints are Silicon moulded to suit GMP/cGMP standards
