Plastic extruder pelletizers in the process of pelletizing broken strips may be caused by a variety of reasons. This paper analyzes the causes of plastic waste recycling pelletizing machine broken strips and the corresponding countermeasures.
External impurities
- Check whether the dead ends of the PP plastic pellet making machine in each link of mixing and discharging are cleaned up.
- Increase the mesh size and number of screens of the plastic extruder pelletizer.
- Try to cover the holes where debris may fall (solid or mesh cover).
Internal impurities
It is mainly due to severe charring caused by the process or PP plastic pellet making machine, and the carbide is brought out into the plastic strip, which causes the strip to break under the action of traction force.
Poor plasticization of materials
Plastic extruder pelletizer extrusion temperature is low or the screw shear is too weak, resulting in the material is not fully plasticized. At this point there will be material lumps, ultimately resulting in broken bars.
Plastic extruder pelletizer exhaust is not smooth
Material moisture is serious, processing water vapor is not timely through the natural exhaust and vacuum exclusion, trapped in the material strip, under the action of traction caused by the broken strip.
