Two mill systems are employed for most coal grinding applications in the cement industry. These are, on the one hand, vertical roller mills (VRM) that have achieved a share of almost 90 % and, on the other hand, ball mills whose share decreased to just over 10 %.

A validated, integrated digital twin of coal mill subcomponents The pilot project for this toolset involved a detailed investigation of the characteristics of a utility scale coal-fired boiler system utilizing different coal qualities and operating under various real-life conditions.
For ball mills there is a curve linking mill capacity with the top size of coal fed to the mill. The reactivity of the coal, measured in the first instance by volatile matter is needed to determine if the mill can be set to provide standard 70% less than 75 micron or a finer or coarser setting is necessary with corresponding alteration to mill
