Abstract
The invention relates to a vertical rotor mill, especially to an impact pulverizer or to a hammer mill for grinding granular material using impact tools (8). Said tools are fixed to a rotating, vertically arranged rotor (7) which is enclosed by a screen (9). The grinding chamber (19) is in turn enclosed by a conic housing (6). The aim of the invention is to simplify access to the screen (9) and to the impact tools (8), and to improve the operating characteristics. To this end, the cone (6) can be lowered together with the screen (9).
