Crushing, Grinding and Reduction in Flour Milling
Grinding gap and particle size are reduced towards the end from roller mills which the grinding begins. The reason for this is that each process has disintegration and contraction while making gradually cutting, sorting and scraping actions during the separation of endosperm and bran. Therefore the grinding gap will be less in the next crushing process. This range varies depending on the

Pulverizer Wikipedia
There are three grinding roller wheel assemblies in the mill grinding section, which are mounted on a loading frame via pivot point. The fixed-axis roller in each roller wheel assembly rotates on a segmentally-lined grinding table that is supported and driven by a planetary gear reducer direct-coupled to a motor. The grinding force for coal pulverization is applied by a loading frame. This
