Mix preparation on construction site

  • The mobile concept of the cold recycling mixing plant means the machine can be used in the direct vicinity of the operation site, saving both money and time.
  • The robust twin-shaft pugmill mixer exhibits high levels of mixing performance with consistent quality.
  • Mixing precisely to formula is made possible thanks to the use of accurate, microprocessor-controlled spraying units for adding various binding agents.
  • The slewing discharge conveyor enables the processed material to either be stockpiled or continuously loaded on to trucks.
  • Solid fold-out or rather extendable supports ensure the machine stands firm and enable it to be quickly and precisely aligned.
