The impact coke granulation on pitch onsumption on carbon anode

All aluminium smelters use carbon anode in their electrolysis cells. Anode is a good electrical conductor. The granulation of coke plays signification role in anode structure. Most of the smelters classify the granulation of coke as follow:1- Coarse 2- medium 3- inter medium 4- fineH.S.P coal tar pitch use as binder of coke particles. Above classifications have special impacts on pitch consumption optimization of pitch consumption (financially& quality) is one of aluminium smelter challenge.This article is to explain about impact of dimension of coke particle on pitch consumption rate.
