UPVC PVC plastic hot cut pelletizing machine

PVC UPVC plastic pelletizing granulating machine line for sale

Description: 

This PVC plastic pelletizing machine is design specializes for recycling the recycled washed plastic PVC plastic flakes/scraps, such as PVC pipe flakes/scraps, PVC sheet flakes/scraps etc.

After processing techniques such as feeding, heating, melt, cutting, cooling etc., the final products are PVC plastic pellets/granules that can be to produce new PVC plastic products.

Features

The screw is made of high tool steel 38 CrMoALA, Special screw combination Euro-style rectangle barrel, reflux refrigeration channel optimized and disposed, which makes temperature difference in D areas smaller.

Innovated design of heater-tightened style insures high efficiency of heat transfer and high longevity of heater.

Working Flow of PVC plastic pelletizing Recycling machine:

Screw feeder → Conical twin extruder →  Cutting → Blower → Storage hopper → Blower → Storage hopper → Electric control panel

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.

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.

Cutting pelletizing: supplied with speed steel and hard alloy steel cutting blades for reliable performance. Compact structure allows less maintenance.

Blower and hopper: to cooling the PVC pellets and storage the pellets.
