Two Stage Extruder Machine for Large Capacity Extrusion Line
1. Application
The SP-75/180 PE compound with CaCO3 granulating machine is specifically designed for high filler masterbatch, soft PVC, and rigid PVC applications such as pipes, wires, and more.
2. Features
The first stage is a TSE twin-screw extruder without a die. It utilizes the combination of barrel and screw to effectively melt, compound, disperse, and deagglomerate thermosensitive materials like PVC under low pressure conditions. The second stage is a single-screw extruder (SJ) that ensures steady melting, compounding, and strand formation due to its lower rotational speed, preventing overheating.
