A Double Blade Sigma Kneader is also known as Double Z Blade Sigma Mixer ,it is a heavy-duty mixer specially designed to handle thick, sticky, and high-viscosity materials.
The sigma kneader mixer are mainly used for mixing,blending and kneading high viscosity material, including Chemical, Dyes & Pigments, Paint, Polymers Plastic, silicon, rubber, iron compounds , Putties, Plastic, Pharmaceuticals, Printing ink, stiff pastes, Ceramic, Insulators , adhesives, polyester Compounds etc. When the two blade rotate at different speed towards each other causing product to be transferred from blade to blade .
When integrated with an extruder discharge system, the sigma kneader machine offers a streamlined process that don’t need the manual to remove processed materials, which increase high efficiency and product consistency.
Sigma mixer, the tangential action of is thoroughly obtained by ‘Z’ (SIGMA) shaped kneading blades, which rotates
Key Features
1. Sigma-Shaped Twin Blades
* Provide intensive kneading, shearing, and folding action.
* Blades rotate at differential speeds for optimal mixing.
2. Integrated Extruder (Screw Discharge System)
The extruder is usually installed at the bottom or side of the sigma kneader chamber.
When the compound material are mixed and blended ,it would come out of the chamber through a die, which allow controlled and continuous discharge.
3. Jacketed Chamber for Temperature Control
The jacked chamber designed sigma kneader supports heating or cooling for temperature-sensitive materials.
4. Heavy-Duty Gear Drive
This style double blade sigma kneader are specially designed for long life under high torque load.
5. Variable Speed Control (Optional)
Allows adjustment based on process needs.
Advantages of the Extruder Discharge System
* Reduced Material Loss: Ensures nearly complete product discharge.
* Consistent Output: Uniform shape and size of discharged product (especially for compounds or preforms).
* Labor Saving: No manual scraping or tilting required,also enhance product efficience and capability for your factories.
* Decrease Cycle Times: With this high efficient sigma kneader ,it speeds up production cycles, especially in batch operations.
Wide Applications Across Industries
The Double Blade Sigma Kneader with Extruder is widely used in:
* Rubber & Elastomers
For mixing and extruding silicone rubber, nitrile, and EPDM compounds.
* Adhesives & Sealants
Ideal for hot melts, polyurethane adhesives, and mastics.
* Polymer Compounds
Used for masterbatch preparation, thermoplastic blends, and reactive mixing.
* Chemical Industry
Processing resins, putties, caulks, and other thick chemical formulations.
* Food & Confectionery
For materials like chewing gum base, chocolate masses, and doughs.
Why Choose a Sigma Kneader with Extruder?
* High-shear mixing for difficult materials
* Safe, enclosed operation
* Consistent quality from batch to batch
* Easy to integrate into automated processing lines
* Ideal for post-heating/forming processes
In conclusion ,the Double Blade Sigma Kneader with Extruder represents a powerful evolution in mixing technology. It brings together high-efficiency kneading and clean, continuous discharge, reducing downtime and enhancing product consistency. For manufacturers dealing with dense and sticky materials, this double blade sigma kneader mixer system is a game-changer.
