A Laboratory Vibro Sifter (also known as a lab vibro sifter, R&D vibro sifter, or small-scale vibratory sieving machine) is a compact vibrating screening device designed for small-batch processing in research and development settings. It is commonly used in pharmaceutical, chemical, food, and other laboratories to separate, grade, and sieve powders, granules, or mixtures based on particle size.
Unlike larger industrial vibro sifters, lab models are smaller (often 8-12 inches in diameter), portable, and suitable for processing limited quantities of material while maintaining high precision and compliance with standards like cGMP (current Good Manufacturing Practice).

Process Operation of Vibrating Screen
This vibrating energy screen is unit consisting of circular pre-tensioned screen mounted on the frame along with vibrating motor. The vibrating motor imparts three plane vibrations to the screen due to revolving eccentric weights. Total assembly is mounted on suitable springs so that it becomes a independent body which vibrates without parting any vibrations to the foundations.
