The project
  • Feeding a weighing station with the five products
  • Transfer the batches from this weighing station to the two turbo mixers
  • At the outlet of the turbo-mixers, fill two buffer silos
  • Feed one of the two materials to five extruders from these silos. Not all extruders run on the same material at the same time.
What was the response?
  • Power supply Weighing unit - The weighing unit consists of two hoppers:
    • The main hopper (250kg) receives the PVC fed from a floor hopper and the CACO3 fed from a Big-bag emptying station (equipped with a stripper).
    • The secondary hopper (15kg) receives the three additives. It is fed by 3 small hoppers.

 

  • Feeding of the turbo-mixers: At the exit of the weighing unit, 2 intermediate hoppers receive the preparations before being transferred.
    When each turbo-mixer is called, the preparation is transferred to it by a flexible mechanical feeder.

 

  • Turbo-mixer outlet: At each outlet, a flexible mechanical feeder fills a buffer silo to store a certain volume of dry-blend.

 

  • Extruder feeding: At the exit of each buffer silo, a line of feeders allows the transfer of each dry-blend to the extruder hoppers.
    Solenoid valves are used to select the material to be fed to each extruder.

 

CONTROL: Each workshop is controlled by an electrical cabinet.
The process is managed by a PLC and touch panel.
