HDPE Film Pelletizer System Description:
This two-stage HDPE film pelletizer system consists of two sets of single screw extruders and combines the function of feeding, plasticization and pelletizing into a single step. The final product produced by this HDPE film pelletizer line are high quality pellets / granules that can be directly put into plastic injection machines or other applications.
HDPE Film Pelletizer System Features:
1.Feeding： The film are fed into the extruders by screw conveyors that are controlled . The feeding system stops automatically when the electric current in the extruder is high and will only resume when the electrical current returns to normal parameters.
2.Plasticzation and degassing: A specialized single-screw extruder gently melts the pre-compacted material. The plastic scraps is melted and plasticized in the first stage extruder and then extruded by the second stage extruder. With this “dual-zone” vacuum degassing system, volatiles such as low molecular weight materials and moisture is efficiently removed. This results in more uniform final products.
3.Melt filtration: This HDPE film pelletizer line makes use of segmented filtration. The first extruder is responsible for removing coarse contaminants via pre-filtration. A high mesh filter is then applied to the second extruder to remove fine particles. This reduces the frequency for changing filtration medias and sieves.
4.Pelletizing:To turn the extruded plastic into granules, a standard die-face water ring pelletizing system is applied. Once the pellets are formed, an advanced dewatering vibration sieve is combined with a horizontal-type centrifugal dewatering machine to dry the pellets for storage.
