Zusammenfassung:There is described a process wherein the raw fuel and a drying and carrier gas are led into a ventilator-mill operated at high speed, and wherein in the ventilator-mill the fuel is pre-comminuted and dried, the coarse fraction is led out from a classifier, e.g. an air-separator and ground to the desired fineness in a roller mill, the grist leaving the roller mill is recycled to the rotary part of the ventilator mill or the classifier, and from the classifier the final fine fraction ready to be combusted is passed directly to the place of application, e.g. burners via the ventilator-mill.
