PVC pellet lines
Counter-rotating twin-screw extruders for producing rigid and plasticized PVC formulations.
Bandera PVC pelletizing lines based on more than 70 years of experience manufacturing counter-rotating twin-screw extruders with diameters of 45-175 mm. The same screw pair processes different rigid and plasticized PVC formulations without mechanical modifications to the machine - with high energy efficiency and a low kW/kg ratio.
Key features
- 2B HTS counter-rotating twin-screw extruder with an L/D 28 barrel
- Horizontal volumetric dosing unit and vertical forced feeder
- Screw thermoregulation with silicone oil in the terminal section
- Pelletizing head with central or side cutting and quick opening
- RGT stainless-steel pellet coolers with a vibrating screen
- Fast format change via a barrel-shifting system
Typical applications
- Rigid PVC compounds for profiles, pipes and fittings
- Plasticized PVC compounds for cables and technical applications
- Recipes with different shares of additives and fillers
