In the world of industrial mixing, Sigma Kneader equipment play a crucial roll in mixing process, especially in processes requiring high viscosity mixing for rubber ,plastic and chemical material in laboratories or pilot plants.
The sigma kneader mixer are mainly used for mixing, kneading and homogenizing of solid & semi solid materials like dough, powders, cream, paste, sludge, Silicone Sealant ,slurries etc.
But what exactly defines the style of a Sigma Kneader, and where are they specifically used? Let’s explore.
What is a Sigma Kneader?
A Sigma Kneader is one kind of heavy-duty mixer which are equipped with two counter-rotating blades (usually sigma-shaped) inside a horizontal, U-shaped trough. The two counter-rotating kneading blades rotate at different speeds ,which create a strong shearing and kneading action ,and thus making the mixed compound material are ideal for mixing high-viscosity materials that are difficult to process with standard mixers.
Style and Structure of Sigma Kneader Mixer
There are several type of sigma kneader mixer equipment including as follows:
* Twin-blade design: One blade rotates faster than the other, ensuring effective kneading and mixing.
* Z- or Sigma-shaped blades: Designed to maximize contact with materials and create a folding and stretching motion.
* Jacketed trough: For heating or cooling, depending on process needs.
* Tilting or bottom-discharge mechanism: For easy removal of finished product.
* Heavy-duty construction: Built to handle highly viscous and sticky materials like rubber, adhesives, and plastics.
These different features make these double blade Sigma Kneaders not only robust but also highly efficient great for kneading and homogenizing very intensive material that hard to mix for ordinary mixer machine .
Wide Application:
Sigma Kneaders are extensively used in veraious industries such as:
1. Rubber and Plastics
* Mixing silicone rubber, EPDM, or PVC compounds.
* High-shear dispersion of fillers and additives.
2. Adhesives and Sealants
Producing polyurethane adhesives, hot melt glues, and sealants.
3. Chemicals
* Processing resins, putty, and high-viscosity chemicals.
* Batch polymerization and blending.
4. Food Industry
Mixing chewing gum base, chocolate pastes, or thick dough.
5. Pharmaceuticals and Cosmetics
Formulating ointments, creams, and toothpaste.
Thereby, whether you are working with resins, rubbers, plastic or reactive chemicals, a Sigma Kneader machine offers reliable performance, consistent mixing, and process versatility.
We design Sigma Mixer ranging from capacity 10 litres lab model up to 5000 litres production models. These sigma kneader mixers are suitable capacity motor and gearbox incorporated considering raw material characteristics.
And also ,since we are direct factory , thus other additional features such as automatic tilting, screw system, heating arrangement, vacuum system can be tailored as per your specific needs .
