Screw elements are the core functional parts mounted onto the shafts inside the barrel of a parallel co-rotating twin-screw extruder. They determine how material is transported, mixed, melted, and pressurized along the extruder's length.
Different functions of different screw elements
| Item | Functions |
| Conveying Elements: | Primarily transport material forward (pumping action) |
| Kneading Blocks (Kneading Elements) | Provide intense mixing, shearing, melting, and dispersive mixing. |
| Reverse Conveying Elements | Restrict flow, create back pressure, increase fill level upstream, and enhance mixing efficiency. |
| Specialty Elements | Primarily enhance distributive mixing (blending without high shear) |
Why they matter
The specific type, length, pitch/angle and sequence of screw elements determine the extruder's performance for a given material and process (mixing quality, melting rate, devolatilization efficiency, pressure build-up, output rate). Configuring the screw profile correctly is crucial for optimal results.
Production process
Choose Nickel alloy to make your screw elements
Why to choose Nickel to make screw elements in Lithium Battery
Superior Corrosion Resistance:
Withstands highly corrosive fluorides (e.g., from PVDF binders) much better than standard steels, preventing pitting and degradation.
Enhanced Wear Resistance:
Significantly reduces abrasion from hard ceramic fillers (like Al₂O₃/SiO₂) commonly coated onto separators, extending element life.
High-Temperature Strength:
Maintains structural integrity and dimensional stability under the sustained high processing temperatures required for separator polymers.
Reduced Metal Contamination:
Minimizes metallic wear debris generation, crucial for preventing internal shorts in sensitive lithium-ion batteries.
