This two-stage nylon pelletizing line is intended for PA6, PA66 and selected engineering-plastic recycling or modification projects. Nylon is moisture-sensitive, so pre-drying, controlled feeding, venting and temperature management must be evaluated before the screw and filtration system are selected.
Material and Process Boundaries
- Clean production scrap, runners or regrind from known nylon grades
- PA6 or PA66 material requiring filtration and re-pelletizing
- Formulations containing glass fibre, fillers or additives after wear review
- Projects requiring staged plasticizing, degassing and melt stabilization
Mixed polymers, unknown flame retardants, excessive moisture or metal contamination can affect melt quality and equipment wear. Representative samples and material data are required.
Recorded Reference Models
| Model | Screw diameter | Screw length | Main motor | Temperature zones | Reference output |
|---|---|---|---|---|---|
| 130 | 130 mm | 3200 mm | 55 kW | 7 groups | 3–4 t/24 h |
| 140 | 140 mm | 3800 mm | 75 kW | 7 groups | 5–6 t/24 h |
| 160 | 160 mm | 4500 mm | 110 kW | 8 groups | 7–8 t/24 h |
The values are taken from the current product record and require confirmation. Usable output depends on nylon grade, moisture, additives, filtration, pellet specification and operating conditions.
Information Required Before Selection
- PA grade, source and material data sheet
- Moisture after drying and contamination level
- Glass fibre, filler, colour or additive percentage
- Required filtration and pellet quality
- Target output and cutting method
- Voltage, cooling water, floor space and operating hours
For formulation trials, compare the laboratory twin-screw extruder and pelletizer. Production compounding projects can also review the co-rotating twin-screw extruder.
