The primary aluminium metal production carbon anode is a high volume product even on the global scale, which can benefit from optimising the aggregate packing. The general impression from literature is that the industry employs relatively simple methods for particle sizing, modified and enhanced by specific knowledge about the materials in question. The study lists examples of current and possible methods for measurement and control. The packing of given particle size distribution is substantially affected by surface roughness and particle shape, factors that normally is addressed empirically. The civil engineering sector uses simple methods for particle sizing, relying on empirical knowledge of the materials. Typically, the Fuller curves - which is a based on sieving - are used: Cumulative % finer than= √(((particle diameter)⁄(maximum particle diameter))) ∙100% Ceramic industry generally involves smaller particle size than anode carbon, and liquid content and factors affecting particle surface effects are important.
