| Abstract Scope |
The possible segregation during filling of alumina into storage silos causes substantial problems in the further aluminium production chain. For example accumulation of finenesses < 45 µm leads to sludge formation inside the electrolysis cells which can result in anode effects.
The present paper reports on the performance, functional and operational experiences with the Anti-Segregation Technology (ASS). The primary advantage of the air-locked ASS is feeding the alumina into the silos with an unchanged grain size distribution between inlet and outlet of the silo.
This paper describes how to integrate ASS Technology and how to use the optimization potential of this technology in several installations up to 50000 tons storage capacity engineered by Claudius Peters. |
