Aluminium Smelting

An important component of the integrated production plant in Freiberg operated by the PYRAL is its aluminium smelter plant.

Worldwide a specific primary energy consumption of approx. 163.730 MJ/t of aluminium is necessary for the production of primary aluminium from bauxite. On the other hand the secondary production of aluminium needs merely 19.505 MJ/t of aluminium and with that only 11.9% of the primary production. Therefore, this metal is very suitable for a recycling material recovery process from Urban Mining (waste as material resource).

The aluminium recovered from the pyrolysis will be smelted in either our  2-chamber hearth furnace or our rotary (salt-drum) furnace. In addition to our Pyralu, additional aluminium scrap with little residual adhesions will be used in the smelting plant.  The heating chamber has a recuperative preheating and low NOx burners.

The aluminium is discontinuously parted-off and transferred into alloy-, cast- and holding furnaces. An inductive metal pump is used.

Our rotary furnace is used primarily for thin-walled aluminium scraps and small grain aluminium.  This allows for lower energy intake and higher yields, consistent with our desire to efficiently use and save our resources. 

A further component of the plant is a Gautschi-cast strip with a fully automatic robot system for stacking and packing the ingots.
