A Pharmaceutical Vibro Sifter (also known as a vibratory sifter, vibro screen, or vibrating sieve) is a critical piece of equipment in the pharmaceutical industry used for separating, grading, and sieving powders, granules, and liquids based on particle size. It ensures product uniformity, removes oversized contaminants or lumps, and eliminates foreign particles, which is essential for maintaining drug quality, safety, and consistency in processes like tablet manufacturing, capsule filling, and granulation.
Pharmaceutical Vibro Sifter are designed to meet strict pharmaceutical standards (e.g., GMP compliance), often constructed from high-grade stainless steel (SS 304 or 316L) for hygiene, easy cleaning, and corrosion resistance.

Process Operation of Vibro Sifter Vibratory Sieve
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.
