Aluminum oxide, aluminum metallic and metal. Aluminum oxide through sieves in the third section engages the bottom of the rotary drum.
Aluminum dross crusher is used to accelerate the recovery rate of aluminum from its dross. In this paper, an attempt has been made to optimize the performance of aluminum dross crusher by optimizing certain parameters affecting the performance of aluminum dross crusher by design of experiments method such as Taguchi method.
A process for preparing calcium aluminate from aluminum dross comprising crushing (10) the dross and extracting solubles therefrom with water in a digester (14). The brine so obtained is processed in a crystallizer (32) to obtain fluxing (32 (a)) materials contained therein, and the insolubles are furnaced (22) to separate the free aluminum metal therefrom.
The aluminum recovery from white aluminum dross by a mechanical treatment and sizing followed by remelting process was investigated. The dross was subjected to a ball mill, and the obtained particles were sized in different ranges. They were studied by advanced materials characterization techniques. It was found that the larger particles contain high metallic portions, and …
