The utility model relates to the construction machinery, in particular to the hammer mills that can be used in mineral resource industry and agriculture for the production of fine powders of loose materials. The hammer mill comprises a proper mill (1) with an outlet branch pipe (2), a separator installed thereon, a cyclone-unloader (3), a bunker for coarse particles return for re-milling and an exhaust fan (4), communicating with the separator. The separator consists of an external conic body (6), an internal conic element (7) coaxial to it and an exhaust branch pipe (5). Novelty consists in that the internal conic element (7) is made with an anterior conicity, forming an annular gap with the external conic body (6), and with a posterior conicity, forming an annular gap with the exhaust branch pipe (5) of the separator. The internal conic element (7) is installed onto a rod, coaxial to the external conic body (6) and with the possibility of movement in axial direction, and the exhaust branch pipe (5) is movably mounted onto the axis of the external conic body (6).
