Abstract
A demand feed strategy is described which ensures optimal feed rates of ore to aluminium electrolysis cells. The strategy is monitored by observing pot voltage and is fine-controlled by adjustment of ore feed rates. Satisfactory operation is achieved by a combination of automatic temporary adjustments made by individual pot controllers and by more permanent manual adjustments of ore feed rates. The feed strategy has been operated for a number of months in the new No 1 potline at Granges Aluminium in Sundsvall, Sweden. It raises current efficiency, reduces the risk of muck formation and reduces energy consumption by limiting anode effect frequency.
