Hot Die 37Kw Twin Screw Extruder Plastic Pelletizing Making Machine With Knife Cutting

SJSZ65/132 Twin screw extruder pelletizing making machine line with knife cutting

Features Specifications for SJSZ65/132 Twin screw extruder pelletizing making machine line: 
The PVC twin-screw extruder granulator is a high-speed twin-screw extruder with forced conveying, high-efficiency plasticizing and mixing and shearing dispersion. The back pressure of the inorganic head is refluxed to avoid high shear and overheating. The lower-stage extruder is a large-diameter single-screw extruder operating at low speed, with independent temperature control, low-speed operating with low shear force, internal cooling of the screw to avoid decomposition of plasticized materials, and single-screw extrusion to ensure the establishment of pressure and stable extrusion Out.

PVC twin-screw extrusion granulator application range: heat-sensitive polymer processing, large-capacity exhaust gas devolatilization treatment. Typical materials: PVC cable material, PVC transparent material, PVC tube material, low-smoke, low-halogen or low-smoke halogen-free cable material, various PE cross-linked materials and rubber dehydration post-processing operations.
