The fan-type mill is employed in the power industry and is used for drying and grinding of coal, supplied for combustion in the powder torches of the steam boilers. By using a fixed baffle-plate (2) in the coal grinding, more even of the grinding plates (5), radial to the previous plate (6), and a hub-type plate (4) is ensured, which extends their operating life. To the fixed baffle-plate (2), at some distance, a deviating deflector (3) is fixed, by means of which the gases, containing abrasive coal powder are redistributed in such a way as to produce more even wear of the grinding plates (5) and the aerodynamic resistance at the inlet of the fan-type mill decreases. 1 claim, 2 figures
