1. Dry cutting process of twin screw granulator
Dry pellet production means that after extruding the strips in the plastic pelletizer, the rotating blades immediately cut them into uniform-length pellets, and then send the pellets to the cooling and sieving device through the pipe by the fan. This pelletizing method is suitable for the mixing and pelletizing of polyvinyl materials.
2. Water ring cutting process of twin screw granulator
Water ring pelletizing production means that the strips extruded by the plastic pelletizer are immediately pelletized by the rotating blade and thrown to the high-speed rotating water ring attached to the inner wall of the pelletizer, and then the water flow takes the pellets to the water separator for dehydration After drying, it is sent to the material cooling device to cool down, which is the finished product. This production method is suitable for mixing and pelletizing polyolefin materials.
3. Underwater cutting process of twin-screw granulator
Underwater pelletizing production means that the strips extruded by the plastic pelletizer are immediately fed into the water to cool down, then cut into pellets, and then the pellets are sent to the centrifugal dryer by circulating water for dehydration and drying. This kind of granulation method is more suitable for mixing raw materials with twin-screw plastic granulator and used for larger batch production.
4. Cold cutting process of twin screw granulator
Cold cutting refers to the material that is mixed and plasticized by the plastic granulator, and then the plastic sheet material is formed from the molding die in front of the barrel, and then it is cooled in the sink and then coiled, and then cut with a special pelletizer grain.
