Abstract The behavior of coal during carbonization and the quality of coke are mainly governed by the grades of coal charged (type and rank) and the operating parameters, bulk density and heating rate. There are several possibilities to increase the bulk density. Among them, compacting of the whole blend before charging into the oven delivers the highest density and the best possible flexibility in the raw material selection. Significantly higher amounts of poor coking coals and other carbon-containing materials can then be used in coking blends. In this chapter, the methods of the industrial coal compacting are shortly presented, and the most relevant parameters influencing the compacting process and compact mechanical stability are discussed. Best practice applications are shown based on extensive experimental works by using specially designed and manufactured experimental setups. The economic performance of coal compacting is shown in the example of the stamp charging process. Coal compacting is a time and energy consuming process. Coal has to be crushed to a certain particle size distribution before compacting. The new developed compact grinding process, combining crushing and preliminary bulk density increase in only one process step, is presented as an approach to reduce the compacting time and consequently the compacting energy, which contributes to improving operational efficiency.
