Twin screw extruder PVC plastic recycling granulator pelletizing machine are applied to the waste materials, which needs high processing performance of melting, volatilization, filtering etc., mainly works for the job of PVC scraps recycling and re-pelletizing.
PVC plastic recycling granulator pelletizing machine with international advanced recycling technology and combined with the actual application condition. 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.
The screw is made of high tool steel 38 CrMoALA or W6Mo5Cr4V2. 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.
The material is used high quality nitride steel, corrosion proof or antifriction with corresponding processed special designed two sets of vacuum.
New-style project of parallel three-axis driving makes the convex axis, convey Chain, decelerate and torque get together, which keep it compact, and the key bearings are imported soakage and spraying lubrication integrate smoothly technics, strengthening of tooth face, so they can ensure high torque, high precision and low noise
The selected material of drive components is dainty, including super intention alloy, cementiteing steel, cementiting and grinding.

Working Flow of PVC plastic recycling granulator pelletizing machine:
1. 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.
2. 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.
3. Cutting pelletizing: supplied with speed steel and hard alloy steel cutting blades for reliable performance. Compact structure allows less maintenance.
4, Blower and hopper: to cooling the PVC pellets and storage the pellets.
