Rigid PP/HDPE Plastic Flake Pelletizing Machine
Convert rigid PP and HDPE flakes into stable, uniform pellets through a two-stage extrusion and water-ring pelletizing process.
Key Advantages
Core process strengths for rigid flake pelletizing.
Two-Stage Extrusion
The first stage handles melting and coarse filtering. The second stage improves homogenization, degassing, and final melt stability.
Intelligent Feeding
VFD-controlled screw feeding keeps material input stable and helps maintain steady output during long runs.
Advanced Filtration
Segmented dual-stage filtration reduces contamination and extends screen-change intervals.
Dual-Zone Degassing
Vacuum degassing removes residual moisture and volatiles, which is important for printed flakes and material with variable moisture.
Working Principle
A two-stage melt filtration and pelletizing flow for cleaner pellets.
Consistent Feeding
Rigid plastic flakes enter through a screw conveyor with controlled feed rate for stable material flow.
First Stage Extrusion
The primary extruder melts and plasticizes the flakes while performing coarse filtration.
Second Stage Extrusion and Degassing
The secondary extruder improves melt uniformity and uses dual vacuum zones to remove trapped gas and moisture.
Fine Melt Filtration
The melt passes through a finer screen changer before pelletizing so the final pellet stream is cleaner.
Water Ring Pelletizing
The die-face water ring system cuts the melt into uniform pellets, then cools and dries them for immediate storage or reuse.
