A Sigma Mixer or Sigma Kneader ,it consist of U trough bowl with two ‘Z’ shape blades each rotates in opposite direction for proper mixing of material . The sigma kneader mixer is used for kneading, mixing, crushing, dispersing for high viscosity, high elastic plastic materials ,like solid & semi solid materials like dough, powders, cream, paste or dough-like materials .
Main Features
* Sigma Mixer is a Batch type Mixer
* Its mixing Trough and Blades can be fabricated in several material ,including mild steel, stainless steel 304 and 316 grade.
* Blades of sigma mixers are designed to obtain thorough mixing of high viscosity materials.
* Sigma mixers have fixed with Heavy-duty gears to sustain of load of Kneading.
Optional Accessories
* Liquid Spray System
* Vacuum System
* Blades Cooling Arrangement
* Screw System
* Automatic Valve Discharge System
With sigma kneader mixer ,what benefit do they bring for you ?
Here , let us simply tell some advantage it has :
1. Mix High-Viscosity Materials
Perfect for rubber, adhesives, dough, battery slurries, etc.
Can handle materials regular mixers can’t process.
2. Provide Intense Shear & Uniform Mixing
Twin sigma blades apply strong mechanical force.
Ensures consistent blending of solids, liquids, or pastes.
3. Handle Heating, Cooling, or Vacuum Processes
Built-in jackets and vacuum options allow:
Reaction control
Solvent removal
Air bubble elimination
4. Improve Product Quality
Reduces lumps, dry spots, and uneven distribution.
Essential for premium product formulations.
5. Save Time & Labor
Fast mixing cycles and powerful blending reduce batch time.
Automation options (e.g., tilting, extrusion discharge) help streamline operations.
6. Enable Custom Production
Can be tailored for:
Capacity (lab to industrial scale)
Discharge methods
Blade speed & ratio
Hygiene levels (for food or pharma)
As we can see ,with the sigma kneader mixer , it can do a lot if you’re working with thick, sticky . So sigma mixers are widely used in chemical, pharmaceutical, food processing, coatings, adhesives, rubber manufacturing, grease and lubricant industries and many other fields.
* Paint & Solvents: Kneading of polyester putty, glass putty, adhesives, sealants
* Rubber & Plastics : Mainly used for Homogenizing, mastication, and color mixing , it can be used for mixing of Rubber compounds, silicone, TPR, PVC plastisols
* Adhesives & Sealants : Mainly used for Blending resins, fillers, and catalysts under controlled temperature or vacuum, applicable for Epoxy, PU, silicone sealants, hot melt adhesives
* Chemicals: Mainly used for High-shear mixing of reactive or hazardous materials ,applicable for Explosives, putty, carbon black masterbatch etc.
* Food Industry: Mainly used for mixing sticky or tough food materials consistently,applicable for chewing gum, dough, candy bases
* Pharmaceuticals & Cosmetics : Mainly used for Homogenization under hygienic conditions, often with heating/cooling, applicable for Ointments, creams, gels, active compound pastes
* FMCG: Blending of liquid soap, liquid detergent
In conclusion, These sigma kneader mixer has become the first choice mixing equipment in many industrial fields as it is commonly suitable for high-viscosity materials, powerful mixing, high efficiency, uniformity, durability and safety. The sigma kneader mixer plays a very important role in chemical, food, pharmaceutical, building materials and other fields, helping to improve production efficiency, product quality and production feasibility.
