A single screw extruder included inPET granulator lineis responsible for melting using a single rotating screw within a barrel and conveying plastic material,pushing it through a die to create a desired shape.
The single screw extruder involves main extruder that is responsible for extruding and melting the plastic and auxiliary extruder that is responsible for further melting the plastic and making it into strips to facilitate granulating process.
It's a fundamental piece of equipment of the PET plastic recycling granulator machine that is known for its simplicity,relatively low cost and ruggedness.
The Key Components of the single screw extruder include screw,barrel,hopper,die,extrusion system,transmission System,heating and cooling System.The functions of these components as follow:
Screw: As the heart of the extruder,it is responsible for rotating and conveying the plastic material forward.
Barrel: It is a heated cylinder surrounding the screw,responsible for melting the plastic.
Hopper:It is responsible for feeding the plastic pellets or powder into the barrel.
Die: It is a shaped opening at the end of the barrel,responsible for shaping the extruded product.
Extrusion System: It involes the screw,barrel and die,responsible for melting and shaping the plastic.
Transmission System: It is used in powering the screw rotation.
Heating and Cooling System: It controls the temperature of the barrel to melt the plastic properly.
