Silicone rubber sigma mixer is screw discharge type. When silicone rubber sigma mixer is in operation:
Two "∑"-shaped blades rotate in opposite directions at different speeds, forcefully shearing, compressing, and kneading the high-viscosity silicone rubber material. After mixing, the material is conveyed by the bottom screw and continuously discharged through the extrusion system.
This structure achieves a combination of high-strength mixing and automatic discharge.

1. High-efficiency mixing capability
Double sigma blades generate strong shear force, enabling rapid dispersion of silica and fillers.
2. Automated screw extrusion
The bottom screw allows for continuous discharge, eliminating the need for manual material handling and improving production efficiency.
3. Suitable for ultra-high viscosity materials
Especially suitable for processing high-viscosity silicone rubber mixtures.
4. Controllable temperature
The jacketed structure allows for heating or cooling, ensuring stable mixing temperatures.
5. Sealed structure design
Suitable for the production of rubber and chemical materials requiring a sealed environment.
