Single screw extruder

pelletizingfor PVCfor EVA

Overview
The planetary roller extruder is designed for feeding calender and calender-coating lines for PVC sheet production and, in two-stage versions, for pelletizing. Single-stage and two-stage configurations are available with a flexible mechanical design adjustable to different formulations. Toothed components are manufactured with high precision to interlock like gear elements, minimizing material buildup and enabling short change-over times.

Your Advantages

• Precise melt temperature control
• Self-cleaning design to reduce residues
• Narrow, controlled residence time distribution
• Balanced ratio of shear to heat transfer
• Short formula change-over times due to continuously interlocking toothed components
