An R&D Vibro Sifter, also known as a laboratory-scale vibro sifter or small vibrating sieve machine, is a compact, high-precision equipment designed for screening, sieving, and grading materials in research and development (R&D) settings. It uses gyratory vibration to separate solid particles based on size, removing impurities or unwanted elements from mixtures of solids-solids or solids-liquids. This makes it ideal for small-batch testing, pilot-scale production, and quality control in labs, where space and precision are key.
Unlike larger industrial models, the R&D version is typically cGMP-compliant, portable, and easy to clean, with features like quick screen changes and dust-free lids. It’s commonly used in pharmaceuticals, chemicals, cosmetics, food processing, and materials science to ensure uniform particle distribution and compliance with standards.

Key Features
-
Vibration Mechanism: Powered by a gyratory motor with eccentric weights, creating three-plane vibrations for efficient separation without damaging delicate materials.
-
Screen Sizes: Often 12-inch (300mm) diameter for lab use, with options up to 20-30 inches; multi-deck configurations allow grading into 2-5 layers.
-
Materials: Stainless steel (SS 304/316) construction for corrosion resistance and hygiene; non-metallic springs to isolate vibrations.
-
Capacity: Handles 10-50 kg batches, with adjustable amplitude and time controls for precise results.
-
Advantages: Low maintenance, energy-efficient (reduced motor HP), quick assembly/disassembly, and suitable for wet/dry sieving.
How It Works
-
Feeding: Material is loaded into the hopper or directly onto the pre-tensioned circular screen.
-
Vibration: The motor generates high-frequency gyratory motion, causing particles to stratify—smaller ones pass through the mesh, while larger ones are ejected via an outlet.
-
Separation: Springs amplify vibrations without transmitting them to the base, ensuring stable operation. Impurities or oversized particles are automatically discharged.
-
Output: Graded material is collected below, with efficiency up to 98% for fine powders.
This process typically takes 3-5 minutes per batch, minimizing downtime.
Applications
R&D Vibro Sifters are versatile across industries:
-
Pharmaceuticals: Sieving powders, granules, and APIs; removing lumps for tablet/capsule formulation.
-
Chemicals: Grading pigments, dyes, fertilizers, and metal powders.
-
Food & Cosmetics: Processing starch, coffee, or cosmetic bases; ensuring particle uniformity.
-
Other: Ceramics, plastics, rubber compounds, and minerals for R&D testing.

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.
