Granules manufacturing machines as important equipment for plastic recycling, often encounter some common failures. If you know some common failures of waste plastic granules making machines, you can repair them in time to ensure production efficiency.
Granules manufacturing machine screw failure
Reason:
- Discontinuous feeding of the hopper
- The feed opening is blocked by foreign matter
- The screw groove is blocked by hard metal objects, and the material cannot be fed normally
Solutions:
Increase the feeding amount to make the screw feed continuously and stably. If it is confirmed that there is a metal foreign body dropped into the screw groove. You should immediately stop the small plastic granulator machine to dismantle the screw and remove the metal foreign matter
Main granules manufacturing machine doesn’t rotate
Reason:
- The power supply of the main motor is not connected
- The heating up time is not enough, or one of the heaters does not work.
Solutions:
- Check whether the host circuit is connected, turn on the power supply
- Check the temperature display of each section and confirm the preheating and warming time
- Check whether each heater has been damaged or has a poor contact phenomenon
small plastic granulator machine vent bubbling
Reason:
- The raw material is not clean enough with impurities
- Feed speed is too fast to make the granules manufacturing machine screw extrusion is not stable
- Plasticizing temperature is not enough to screw extrusion
Solutions:
- Clean the raw material before feeding or replace the filter screen
- Reduce the amount of feed to stabilize the plasticization
- Increase the waste plastic granules making machine plasticizing temperature
