Aluminium dross processing system ALDROS


The most economical and least polluting method to use aluminium dross

The basis of the ALDROS technology is the conservation of metal by immediate stopping of the combustion so that no gases or vapours are released.

The most striking economic advantages are:

  • maximum separation of liquid metal
  • high percentage of metal in the final     product
  • no specific operation staff required
  • low maintenance costs
  • short amortization period

    • Positive environmental aspects:
  • no dust
  • no smoke
  • no bad odours

    • Aluminium technology as fully automatic process

    Handling:
  • The hot dross container is put onto     the lifting platform of the ALDROS     plant
  • Liquid metal is drained by opening     the hole
  • Starting the machine produces     further separation of liquid metal     in a closed atmosphere

    • Automatic processing:
  • In a hermetically sealed atmosphere a rotating     scoop feeds portions of hot dross from the dross     container into the cooling drum
  • In the inner tube hot dross is indirectly cooled by     water circulating in the double-jacked tube
  • DP-plants are milling the cooled dross without     intermediate handling and separate metal from     oxide
  • The metallic products are discharged by a     vibrochute
  • The oxide dust is sucked through pipes to the bag     filter and discharged
  • The program stops automatically as soon as the     processing is completed




    • ALDROS - Compact plants

    In these plants the remaining dross after the draining of liquid metal is cooled and subsequently separated from the oxide in an integrated autogenous mill.

    The products - coarse and fine metal fraction - can be remelted directly.

    The corresponding dust filter eliminates the oxide dust from the milling drum and the flue dust at the discharge.
