Suitability :
Mostly suggested for virgin, next to virgin or plant waste materials. HDPE, LDPE, LLDPE, BOPP FILM and PP natural.
How It Works :
In the entire process, A plastic material, normally in flakes form is placed into hopper of extruder, usually made from fabricated from mild steel or fabricated from stainless steel as per material requirement. There is a hopper magnet fitted inside the hopper to stop metallic particles from entering inside the barrel. The raw material in the form of flakes, is gravity fed into the hopper and through the feed throat, drop on the rotating screw. Barrel has a air vent for degassing the material and machine contains the AC frequency drives to adjust the motor rpm. Barrel has several amount of heaters fitted on the outer diameter. Which heats up the barrel to get extrusion process job done. Screw is connected with helical gearbox and AC motor which helps to rotate the screw. Raw material in flakes form starts to move forward along the rotating screw and enters the heating spot of barrel. Where it starts to melt. Molten plastic reaches the end of the barrel where hydraulic screen changer is fitted which filters the molten plastic and leads it to the die face cutting unit where sharp blade is rotating on high rpm on face of outer side backer plate of the screen changer. This blades cuts the molten plastic into round shaped pellets. Entire cutting process occurs In presence of constant water circulation. Finished pellets travels to the de watering unit along water flow. In de watering unit, pellets get completely dry and travels to the storage silo with the help of hot air blower.
