Abstract
In the process and the apparatus, a gas stream is divided into three partial gas streams. The first partial gas stream transports the material to be ground into the grinding and friction space of a mill (26), while the second partial gas stream runs around the friction space in the mill. The third partial gas stream is connected to the output side of the mill and takes up the reduced and dried ground material, transported out of the mill by the first and second partial gas streams, in order to transport it to a separator (30).
