Double Cone Blender

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 of Double Cone Blender:

1. Vessel: Comprises two conical sections joined at their bases.
2. Drive System: Typically includes a motor and gearbox to rotate the vessel.
3. Support Frame: Holds the vessel and allows it to rotate.
4. Loading and Unloading Ports: For adding materials and discharging the mixed product.
5. 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.
