The recovery rate can be 91% and the burning rate of aluminum can be reduced to 4%. Our aluminum machine belongs to this type of dross machine and it has a high recovery rate, no need for any fuel, and a short working time, processing 100-600 kgs aluminium dross in 10-12 minutes. The pressing recovery process method.

The recovery of aluminum depends on many factors. The aim of this work is to experimentally investigate aluminum recovery under different conditions. In this study, aluminum dross was processed in a direct-current electric-arc rotary furnace. The presence of crushing refractory bodies during processing was found to increase the …

In contrast, salt-free re-melting processes require cleaner scrap and generate dross-a mix of oxides and entrapped Al-as residue, which is then recycled in rotary furnaces with salts, although ...

According to Gil (Gil, 2005), Zaragoza based company IDALSA focuses on processing secondary wastes from aluminum industries. The technology adopted includes the oxy-combustion, pretreatment of the wastes, use of 18 ton tilting …

In the presented work, a study is conducted on the formation and possible further processing of aluminium dross. Within the scope of this experimental work, the pyrometallurgical treatment of Al-dross in the salt drum furnace was evaluated on the basis of an experiment in a TBRC (top blown rotary converter) by adding a salt mixture.

RECYCLE SALT-FREE ALUMINUM WITH THE NEW TRF DESIGNED BY DROSS ENGINEERING. The TRF furnace (tilting rotary furnace) used to melt aluminum scrap has demonstrated for more than 20 years that it is the best furnace for melting aluminum waste (cans - rolled profiles - paper - chips and dross ) It also demonstrated that it had the best …

9.2.1.3 Salt-Free Processing of Hot Aluminum Dross. This innovative process, described by Drouet and coworkers (2000) makes possible in-plant recovery of aluminum. It is named DROSRITE process, in which hot dross is charged to a refractory-lined rotary furnace, immediately after skimming from the aluminum holding furnace. The furnace is sealed ...

It is known that calcining the dry aluminum dross waste in a rotary furnace at a temperature above 982 °C yields a refractory product comprising majorly corundum (α-Al 2 O 3) and spinel (MgAl 2 O 4) (Yoshimura et al., 2008).
