Soft Plastic PVC transparent particles pelletizing recycling granulating Line

PVC Granulating Production Line is mainly used for the PVC powder pelletizing；lt is the necessary equipment for the PVC injection machine and some special PVC products making. Application Rigid PVC granule, soft PVC granule for different kinds of profile or cable.

Production process flow:
Dose feeding → Conical twin screw extruder → Blowing hot-cutting mould → Blowing system → Vibrating screen&air cooling → Blowing system → Storage hopper → Finished product packing



Features of PVC granulating line:
A1. Screw feeder: the first step of the pelletizing recycling machine, PVC plastic flakes/scraps conveyed into the hopper through screw, the screw connect sensor to detect the material in hopper, once the flakes are full in hopper, the screw will stop; and once empty, the screw feeder will begin working.
A2. Extruder: to plasticization and degassing, a specialized single screw extruder applied to melt the pre-compacted material. The plastic scraps will well melted, plasticized in the first stage extruder, and the plastic will be extrude by the second stage extruder. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to heavy printed film and material with some water content.
A3. Non-stop hydraulic screen filter changer: double stage filtering, fore filtering in the first extruder, and fine filtering in the second extruder, to reduce the frequency of filtering sieves changing. The requirements on the filter technology depend heavily on the quality of the input material as well as the planned use of granules.
A4. Cutting pelletizing: supplied with speed steel and hard alloy steel cutting blades for reliable performance. Compact structure allows less maintenance.
