Bottom Discharge Sigma Blade Mixer

Bottom Discharge Sigma Blade Mixer Equipment Parameters

Key Features of Bottom Discharge Simga Blade Mixer

• Zero-Dead-Zone Bottom Valve Design: Features a custom-engineered hydraulic or pneumatic bottom valve (ball valve or flush-bottom valve) that conforms to the cylinder's curvature, completely eliminating material residue and accumulation in dead zones.
• High-Vacuum/High-Pressure Sealing: Maintains an airtight seal throughout the process—without the need to tilt the vessel—preventing solvent evaporation, oxidation, and external contamination.
• Efficient, Rapid Discharge: Utilizes a combination of gravity and agitator blade thrust to allow high-viscosity pastes to discharge directly into downstream process vessels or pump inlets.
• Modular Heating/Cooling Jacket: Supports electric heating, thermal oil heating, or water cooling, ensuring precise control over reaction and mixing temperatures.

Key Valve Types and Discharge Configurations

1. Hydraulic flap valve (segment valve): The valve plate conforms to the curvature of the cylinder bottom and opens by flipping downwards or to the side. It features minimal dead zones and excellent sealing performance, making it suitable for medium-to-high viscosity compounds and pastes.
2. Ball valve/Butterfly valve (large-bore): suitable for materials with good flowability, relatively low viscosity, or a semi-fluid state; these valves offer simple operation and facilitate automated control.

Bottom Discharge Sigma Blade Mixer Typical Applications

Bottom discharge sigma blade mixer is widely used in industries requiring specific flow characteristics for viscous materials or necessitating sealed reaction and degassing processes:

• Silicone sealants / Glazing sealant base: Kneading, dehydration, and degassing of high-viscosity base materials.
• Polyurethane (PU) adhesives & Resins: Moisture-proof, sealed mixing with direct bottom discharge into packaging.
• Hot melt glue & Butyl sealants: Melt-blending via jacketed heating and high-temperature bottom discharge.
• Electronic thermal conductive pastes / Silicone greases: High-thermal-conductivity pastes requiring high purity and a bubble-free finish.
• Pharmaceutical & Food pastes: Compliant with GMP cleanliness standards and designed for easy CIP (Clean-in-Place) processing.

The bottom discharge sigma blade mixer features a high-performance discharge valve integrated at the lowest point of the vessel bottom. During the mixing process, the valve seat sits flush with the inner wall of the vessel, eliminating dead zones; upon completion of mixing, the bottom valve is opened, and the Sigma blades rotate in the discharge direction to ensure rapid and clean material unloading. This setup is particularly well-suited for products that do not require granulation but demand exceptionally high standards regarding containment, cleanliness, and operational safety.
