What Is Sigma Mixer?

8.26 (1)
Sigma Mixer, also named Kneader Mixer or Z Blade Mixer, is an ideal sigma mixer machine for kneading, mixing, vulcanization and polymerization of high-viscosity and elastoplastic materials.

How Does a Sigma Mixer Work?

Sigma Mixer machine has two blades rotating in opposite directions and is arranged in a side-by-side tangential differential type configuration, where one blade rotates faster and the other rotates slower. This design generates shear force, and the different rotational speeds enable the mixed materials to be rapidly sheared, ensuring that the materials can be thoroughly mixed with excellent mixing performance.

How About Sigma Mixer’s Blade?

Sigma Mixer machine blades can be sigma type or Z type, which are designed for different material processing requirements.

Sigma type blade has the features of strong extrusion, folding and self-scraping walls. It is suitable for elastic-plastic materials that require degassing and dehydration.

Z type blade has the characteristics of high shear, stretching and dispersion, and is suitable for the shearing, crushing and dispersion of high-viscosity materials. These blade designs enable the sigma blade mixer to achieve efficient mixing performance for different applications.

Does A Sigma Mixer Have Other Functions?

Sigma Mixer machine can be equipped with additional functions according to different processing requirements, including:

1. Heating and Cooling System 

2. Vacuum Mixing System 

3. PLC Control System 

4. Explosion-Proof Design 

How Does Sigma Mixer Discharge?

Sigma Mixer machine has three common discharge methods:

1. Hydraulic Tilt or Manual Tilt 

2. Screw Extrusion (Screw Extruder) 

3. Bottom Valve 

The Application Of Sigma Mixer

Sigma Mixer machine is widely used for the mixing, kneading, crushing, stirring, vulcanization, and re-polymerization of high-viscosity and highly elastic-plastic materials. The sigma mixer has the advantages of uniform mixing, no dead corners, and high kneading efficiency, making it suitable for high-viscosity material processing applications.|
Sigma Mixer can be used for sealants, neutral glass glue, acidic glass glue, hot melt adhesives, silicone rubber, butyl rubber, rubber, pulp, cellulose, batteries, inks, pigments, dyes, pharmaceuticals, resins, plastics, cosmetics, carbon paste, clay, plasticine, BMC, explosive materials, and other chemical products. It can also be used for food products such as dough, syrup, chewing gum, bubble gum, chocolate and other high-viscosity materials.
