    5. The output capacity will depend on the quality of waste to be regranulated
    6. Die-face cutter of repelletizer - the melt is pressed out through a perforated plate, cut off in hot condition by a rotating knives and pelletized by a centrifugal water cooling system
    7. Runs through the vibration sieve for drying and with the quick rotary motion concludes the drying prior to transporting finished pellets to the cyclone for temporary storage
    8. The agglomerator process is done between the shredding process and the feeding process through the conical long-term nitrated screw plasticizes and homogenizes the material in one operating cycle
