A Vibro Sifter , also known as a vibratory sifter ...

A Vibro Sifter, also known as a vibratory sifter, vibrating sieve, or vibrating screen, is a versatile industrial equipment used for separating, grading, and filtering powders, granules, and liquids based on particle size. It’s commonly used in the pharmaceutical, food, chemical, cosmetic, and nutraceutical industries.

🔧 How It Works:

The vibro sifter uses vibratory motion generated by a motor with eccentric weights. This vibration causes the material fed onto the screen to move across the surface, allowing particles of a specified size to pass through while larger ones remain on top.

🧩 Main Components:

1. Screen Deck(s):

• Circular frames fitted with mesh (wire screen or nylon) that determines the particle size separation.
• 
  
• Multi-deck designs can separate material into multiple size fractions in a single pass.

1. Vibratory Motor:

• Mounted centrally or on the side, it generates high-frequency vibrations.

1. Base & Frame:

• Provides support and stability to the unit.

1. Outlet Chutes:

• Separate chutes for fines (passing through mesh) and oversize material.

1. Cover (Optional):

• A lid with inlet port helps reduce dust and contamination—especially important for pharmaceuticals.

⚙️ Working Principle:

1. Material is fed from the top into the central inlet.
2. Vibrations cause the material to move in a spiral or horizontal motion across the mesh.
3. Smaller particles pass through the mesh and are collected from the bottom.
4. Oversized particles are discharged from the top outlet.

✅ Advantages of Vibro Sifter:

• High throughput with fine accuracy
• Compact & portable design
• Low maintenance
• Dust-free operation (with sealed lid)
• Can be used for both dry and wet sieving
• Quick screen changeover
