Plastic pelletizer plants process waste plastic debris into pelletized plastic through a series of processes, providing a reusable raw material for manufacturing new plastic products. The pelletizing system is crucial in a plastic recycling granulating line.
Pelletizer mainframe: high-temperature melting and extrusion
The plastic pieces are first fed into the mainframe of the plastic pelletizer plant, where the high temperatures and high pressures help to melt them completely. At high temperatures, the plastic pieces gradually soften, melt, and turn into a viscous plastic substance. Once the plastic is completely melted, it is extruded into molten plastic strips that exit the main plastic pelletizing recycling machine. These strips have a large cross-sectional area so that subsequent steps are easier to carry out.
Plastic pelletizer auxiliaries: drawing and re-extrusion
Next, the extruded plastic strips from the main machine pass through the plastic pelletizing recycling machine’s auxiliary machine. The process here is similar to wire drawing, in that the coarse strips are extruded by the waste plastic recycling pelletizing machine die into spaghetti-like thin strips. This process not only makes the strips more uniform but also increases the ease of subsequent processing.
Cooling and pelletizing
After re-extrusion, the plastic strip enters the cooling section. At this stage, the strips are rapidly cooled to a more stable state by utilizing a cooling tank. The cooled plastic strip passes through a plastic pellet cutter where it is cut into pellets of specified lengths. These small granules are the final product and they are called plastic pellets.
