Plastic Recycling Pelletizing Line with Hot Cutting Device

Plastic Recycling Pelletizing Line with a Hot Cutting Device is a specialized setup used in the recycling of plastic waste into pellets. This system includes several stages, focusing particularly on the pelletizing phase, where a hot cutting device is utilized to cut the extruded plastic into uniform pellets.

1. Pre-processing
Sorting and Crushing: The plastic waste is first sorted and crushed into small flakes or pieces.
Washing and Drying: The crushed plastic is washed to remove contaminants and then dried to eliminate moisture.
2. Melting and Extrusion
Feeding: The clean, dry plastic flakes are fed into an extruder.
Melting: Inside the extruder, the plastic is heated and melted. The temperature and screw design vary based on the type of plastic being processed.
Extrusion: The molten plastic is pushed through a die to form continuous strands or spaghetti-like shapes.
3. Hot Cutting
Hot Cutting Device: As the plastic strands exit the die, they are immediately cut into small pellets by a hot cutting device. The hot cutter uses rotating blades that slice the strands into uniform pellets while they are still hot and malleable.
Water Cooling: The hot-cut pellets are then cooled, typically using a water flow system that cools and conveys the pellets away from the cutting area.
4. Post-processing
Drying: The cooled pellets are dried to remove any surface moisture from the water cooling process.
Screening and Classification: The pellets are screened to remove any oversized or undersized pieces, ensuring uniform pellet size.
Quality Control: The pellets undergo quality checks to ensure they meet the required specifications, including size, color, and physical properties.
