Two tonnes of alumina is required to produce one tonne of aluminium. The logistics of alumina therefore represent an important part of the aluminium production, including unloading of ships, internal transport and storage, fume treatment and finally distribution into the electrolysis pots. Over the last 20 years several automated distribution systems utilizing pneumatic conveying have been developed. These systems are closed, resulting in less dusting. However, due to the erosive properties of alumina and relatively high transport velocities, such systems require high maintenance frequencies. Problems also arise because secondary alumina forms scales when conveyed pneumatically.
