The anode material needed to fuel the electrolysis consists of carbonaceous coke with pitch as binder. To produce this anode paste in the correct composition, the petroleum coke is crushed, dried, milled, sieved, sifted, and strictly separated for intermediate storage. Then, the milled coke is precisely weighed, preheated, and mixed with coal tar pitch serving as a binding agent. The coal tar pitch binding agent is directly injected in liquid form to the BUSS Kneader processing chamber. Its purpose is to shroud and penetrate the pores of the coke grains so as to bind them into a pasty mass. This compounding step plays a major role in anode production. The quality of the final anode mass has a significant influence on the properties of the aluminium. In order to achieve sufficient mixing quality and homogeneity, the specific energy input per ton into the anode mass during the preparation process is of great importance.
