What are the advantages of twin screw extrusion?
The twin screw extrusion machines mix the ingredients, mainly polymers with inorganic fillers, reinforcements or other additives, or are used to obtain desired chemical reactions in a continuous and controlled way.
What is twin screw extrusion?
Extrusion is conventionally a continuous process which consists of transforming the matter inside a screw/sleeve system and forming it.
More simply stated, the co-rotation twin screw extruder is a machine consisting of two identical co-penetrating and self-cleaning screws which turn in the same direction inside the bore of a fixed envelope called a sleeve.
Clextral twin screw extruder
What are the advantages of twin screw extrusion in chemical, plastic and bio material applications?
Clextral twin screw extruders offer exceptional versatility to perform the following functions:
- Continuous chemical reaction
- Continuous mixing/blending
- Micro-mixing/macro-mixing
- Defibration
- Solid/liquid extraction
- Melting
- Degassing/devolatilisation
- Cooling
- Forming
The twin screw extrusion technology represents a strong substitution potential for conventional technologies implemented in chemistry and offers the following advantages in terms of:
• Sober and intensified processes (efficiency, capacity, continuous process, etc.)
• Control of the reaction (temperature, pressure)
• Homogeneity and reproducibility
• Confinement of the reaction (to better protect men and the environment)
