In the method and the device, a gas stream is divided into three partial gas streams. The first partial gas flow conveys the ground material into the grinding and friction space of a mill (26), while the second partial gas flow circulates around the friction space in the mill. The third partial gas stream is connected to the outlet side of the mill and receives the ground and dried …
