A Double Cone Blender is an industrial blending machine designed for the uniform mixing of dry powders and granules. It consists of a double-conical rotating vessel that ensures even distribution of materials by continuously tumbling them. This blender is widely used in industries such as pharmaceuticals, food, chemicals, cosmetics, and nutraceuticals for gentle yet effective mixing without material degradation. Components of Double Cone Blender 1. Double Cone Vessel A rotating, conical-shaped mixing chamber where materials are loaded. Designed to prevent dead zones and ensure uniform blending. Made of stainless steel (SS304 or SS316) for hygiene and durability. 2. Rotating Mechanism The vessel is mounted on a rotating shaft driven by an electric motor and gearbox. Rotates at a controlled RPM (Revolutions Per Minute) for optimal mixing. 3. Loading & Discharge Ports Top Opening: For feeding raw materials (manually or using a vacuum system). Bottom Discharge Valve: For emptying the blended material. 4. Safety Features Interlocking system to prevent operation if the lid is open. Emergency stop button for immediate shutdown. Dust-proof sealing to prevent contamination. 5. Optional Attachments Jacketed Design for heating/cooling if temperature-sensitive blending is required. Automated Material Loading System for high-capacity production. Working Process of Double Cone Blender Step 1: Loading the Materials The required powder or granular materials are fed into the mixing chamber. Loading is done manually, by vacuum transfer, or screw conveyor. The fill level is typically 50-60% of the total volume to allow free movement. Step 2: Rotational Mixing The blender is switched on, and the double-cone vessel starts rotating. The tumbling action causes particles to mix uniformly by continuously rolling and cascading inside the chamber. Step 3: Homogeneous Blending The materials are evenly distributed due to the vessel’s conical shape and smooth movement. The mixing time varies depending on material properties (typically 10-30 minutes). Step 4: Discharge of Blended Material Once mixing is complete, the discharge valve is opened. The blended product flows out smoothly due to the gravity-assisted cone design. Some models have a vibratory system to assist in complete discharge. Step 5: Cleaning & Maintenance The blender is cleaned after every batch to prevent contamination. Some machines have CIP (Clean-In-Place) systems for automatic washing.
