Product Details

Raw material of bio-plastic, starch and plasticizer are fed into twin screw extruder via accurate LIW feeders separately with high automation and flexiblity to adjust formulation. Modular twins crew extruder equipped with super high torque gearbox,wear resistant & corrosive resistant barrels and screw elements, high torque shaft and safety clutch, efficient heating and precise control to ensures table, reliable and long term production.

Air cooling bed are designed with enough length to cool the melt strand off before cut by a traditional pelletizer, the whole system is simple and operated easily. Advance underwater cutting system can produce elliptical pellet with high automation, the closed system has no emission of smoke and dust to environment and can adapt to various capacity requirements. Rich and reasonable downstream equipments realize homogenization, sieving, drying&cooling until automat-ic packing smoothly.
Due to its low vibration and low noise level,the main extruder can be installed on most solid grounds with no need for any special base.

  • Specially manufactured screw and barrel to guarantee precision and quality
  • International brand variable speed control motor to precisely control the screw rotating speed
  • SIEMENS touching screen PLC control system,highly intelligent, easy to operate.

Application Scope of the Biodegradable pelletizer
