Dross Engineering B37 battery breaking & separation video.

In 1970, Jean Armabessaire, President of Dross Engineering, delivered the first ‘transportable’ de-ironing furnace.

The furnace was shipped completely lined and ready to operate. This was a real innovation at the time because furnaces then did not have a casing and were built completely out of bricks.

The first oil crisis forced furnace builders to develop new energy saving techniques as ‘good’ furnaces of the time consumed 150 litres of oil (or equivalent in gas) per tonne.

Since then Dross Engineering has developed furnaces providing secondary smelters with ever increased performance and economy.

In 1990 they produced their first pilot TRF (Tilting Rotary Furnace) inspired by a very old technique and applied to melting aluminium.

The objective was to combine in a single furnace the advantages of several types of furnace: reverbs, dry hearths, and fixed axis rotaries; and above all to eliminate of greatly reduce the use of salt.

Today over 10 furnace builders worldwide offer their customers tilting rotary furnaces or TRF. These ‘revolutionary’ furnaces can melt at record speed practically the whole range of aluminium scrap, with or without salt, and offering energy returns of 350 – 400 kW per tonne, some 4 times less the in 1970.

Dross Engineering has a ‘honorable’ reference list with to-date some 38 TRF installed iin 20 different countries. Dross Engineering furnaces are fitted with the latest technologies such as oxygen probes, optical pyrometers with video and charge management etc…
