Sigma kneading machine (also known as Double Sigma mixer or Double Z-type paddle mixer) is a mixing equipment designed specifically for high viscosity materials (over 500000 CPS), widely used in the chemical, food, sealing materials, rubber and plastic, paint and dye, and petrochemical industries.

Sigma kneading machine (also known as Double Sigma mixer or Double Z-type paddle mixer) is a mixing equipment designed specifically for high viscosity materials (over 500000 CPS), widely used in the chemical, food, sealing materials, rubber and plastic, paint and dye, and petrochemical industries。

Structural Design

Adopting Z-shaped propeller blades, installed in two semi cylindrical bodies, efficient mixing is achieved through compression, stretching, folding, kneading and other actions.

Some models support electric heating, steam heating, water cooling, and hydraulic cylinder flipping functions, such as stainless steel kneading machines that can be paired with vacuum pumping systems.

Application scenarios

Suitable for mixing high viscosity materials such as hot melt adhesive, butyl rubber, carbon, etc., some models support screw extrusion or hydraulic flip operation

1、 Main types

1. ‌普通型‌
   Basic equipment, suitable for the initial mixing of general materials such as silicone rubber and sealant.

2. ‌Vacuum type‌
   Equipped with a vacuum system, it can remove material bubbles and is suitable for the production of bubble free finished products such as silicone rubber and glass glue.

3. ‌high-temperature type‌
   The working temperature can reach 400 ℃, controlled by electric heating or thermal oil, specifically designed for processing high-temperature resistant materials such as APP flame retardants and high-temperature sealants.

4. ‌Laboratory type‌
   Small capacity (5L-50L), compact structure, suitable for research and development testing, supporting screw discharge and vacuum function.

2、 Core structure

• ‌mixing systemAdopting Z-shaped or ∑ - shaped double blade differential design to achieve shear and extrusion mixing.

• ‌Heating/CoolingThe jacket structure supports temperature control for steam, thermal oil, or water circulation.

• ‌出料方式Hydraulic flipping cylinder, screw extrusion or ball valve feeding, adapted to different material characteristics.

• ‌materialThe contact parts are mostly made of SUS304/316L stainless steel to ensure corrosion resistance and hygiene requirements.

3、 Typical applications

• ‌chemical industryMixing and dispersing of silicone rubber, sealant, and ink.

• ‌Food and MedicineUniform mixing of paste condiments and pharmaceutical preparations.

• ‌Special materialsReaction processing of carbon, flame retardants and other high-temperature and high-pressure environments.

4、 Purchase suggestions

• ‌Capacity selectionIndustrial use typically ranges from 100L to 4000L, while laboratory use typically ranges from 5L to 50L.

• ‌Function ConfigurationChoose vacuum, high temperature, or pressure type based on material characteristics.

Regular lubrication of transmission components and inspection of sealing systems are required during maintenance to extend equipment lifespan
