PP HDPE 경질 플라스틱 플레이크 펠렛화 시스템

This two-stage HDPE flakes pelletizing system consists of two sets of single screw extruders and integrates the function of feeding, plasticization, and pelletizing into a single step. The final product generated by this pelletizing machine are high-grade pellets/granules (see additional images below) that can be directly put into plastic injection machines or other applications.

작동 원리

급송: The flakes are fed into the extruders by screw conveyors that are managed by VFD. The VFD feeding system halts automatically when the electric current in the extruder is elevated and will only resume when the electrical current returns to standard parameters.

가소화 및 탈기: A specialized single-screw extruder delicately melts the pre-compacted material. The plastic scraps are 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 substances and moisture are effectively removed. This results in more consistent final products.

용융 여과: This system utilizes segmented filtration. The first extruder is tasked with removing coarse contaminants via pre-filtration. A high mesh filter is then applied to the second extruder to eliminate fine particles. This lowers the frequency for changing filtration media and sieves.

작은 알모양으로 하기: To convert the extruded plastic into granules, a standard die-face water ring pelletizing system is employed. Once the pellets are formed, an advanced dewatering vibration sieve is paired with a horizontal-type centrifugal dewatering machine to dry the pellets for storage.
