Claims (1)

Claim A medium-speed mill containing a housing with a grinding chamber, grinding table and rolls, ring armor placed on the housing opposite the grinding table, a nozzle apparatus formed by the lateral surfaces of the latter and armor, and drying agent supply pipes installed in the housing under the grinding table, Including with the fact that, in order to reduce aerodynamic losses, energy consumption and metal consumption. the annular armor is installed with the possibility of vertical movement along the housing, and spiral or inclined channels are made on its side surface 15, the number of nozzles for supplying the drying agent being equal to the number of rolls and each of the nozzles installed tangentially under the corresponding roll in the housing, and 20 the distance between the channels increases in the direction of flow of the drying agent from the corresponding pipe. ba FIG. 3
