Introduction to Plastic Pelletizer Machines
Plastic pelletizer machines are essential in the recycling industry, transforming plastic waste into valuable raw materials. These machines play a crucial role in producing high-grade plastic pellets, boosting profit margins and earning customer trust (www.plasticrecyclingmachine.net).
How Plastic Pelletizer Machines Work
The process begins with dehydrated plastic fragments entering the main machine for heating and melting. The melted plastic is then extruded and drawn through the die head, achieving granulation (shuliyplastic.com). The extrusion system includes screws, barrels, hoppers, heads, and mold heads, while the transmission system consists of motors, reducers, and bearings.
Types of Plastic Pelletizer Machines
Single Screw Pelletizers
