Abstract
Systems, methods and apparatus relating to evaluation of alumina feedstocks are disclosed. A system may include an alumina storage unit comprising an alumina feedstock, an alumina supply member in communication with the alumina storage unit and an aluminum electrolysis cell. The alumina feedstock of the alumina storage unit may periodically flow through the alumina supply member and to the aluminum electrolysis cell. A measurement device may be in communication with the alumina supply member, and may be configured to measure a supply member property and transmit a first signal to a processor. The processor may be configured to receive the first signal and produce supply member property data based, at least in part, on the first signal.
