Principles of Twin Shell Blender (V-Blender):
The twin shell blender, or V-blender, operates on the principle of diffusive blending, utilizing the tumbling motion to mix materials.
Construction:
Vessel: Two cylindrical sections joined at an angle to form a V-shape.
Drive System: Includes a motor and gearbox for rotation.
Support Frame: Holds the vessel securely.
Loading and Unloading Ports: For adding and removing materials.
Optional Intensifier Bars: To enhance mixing of difficult-to-blend materials.
Working:
Materials are loaded into the V-shaped vessel.
The vessel rotates, causing materials to tumble and cascade within the two arms of the V.
The repetitive movement leads to thorough blending of the materials.
After achieving the desired blend, the contents are discharged.
Uses:
Pharmaceuticals: Blending powders and granules.
Food Industry: Mixing dry ingredients.
Chemical Industry: Blending fine chemicals and powdered materials.
Merits:
Efficient for free-flowing and dry materials.
Simple and effective design.
Gentle mixing action, preserving particle size and shape.
Easy to clean and maintain.
Demerits:
Inefficient for cohesive or sticky materials.
Limited to batch processing.
Not suitable for large-scale production due to volume constraints.
