Principles of Double Cone Blender:
The Double Cone Blender operates on the principle of tumbling action.
It achieves mixing by rotating a conical vessel, causing the contents to continuously fall and disperse, promoting thorough intermixing of the particles.
Construction:
Vessel: Comprises two conical sections joined at their bases.
Drive System: Typically includes a motor and gearbox to rotate the vessel.
Support Frame: Holds the vessel and allows it to rotate.
Loading and Unloading Ports: For adding materials and discharging the mixed product.
Optional Features: May include intensifier bars for breaking up agglomerates and ensuring uniform mixing.
Working:
Materials are loaded into the blender.
The vessel rotates around its axis, causing the particles to tumble and cascade.
The continuous movement ensures that particles intermix, achieving a homogeneous blend.
Once mixing is complete, the blender is stopped, and the contents are discharged.
Uses:
Pharmaceuticals: Mixing powders and granules.
Food Industry: Blending dry ingredients like spices and baking powders.
Chemical Industry: Mixing fine chemicals and dry powders.
Merits:
Simple design and operation.
Effective for free-flowing powders.
Minimal heat generation, suitable for heat-sensitive materials.
Gentle mixing action, preserving particle integrity.
Demerits:
Not suitable for sticky or cohesive materials.
Limited mixing efficiency for very fine powders or particles with large density differences.
Requires regular maintenance to ensure smooth operation.
