Abstract
A roller mill has a mill housing having a vertical axis. A coaxially aligned grinding track is arranged concentrically about the vertical axis and supports a plurality of grinding rolls. The mill housing is divided into a force-conducting housing part which absorbs horizontal grinding reaction forces and an air-ducting housing part which contains an air-ducting chamber and is mounted below the force-conducting housing part. The force-conducting housing part is supported on the foundation by supports. The air-ducting housing part is detachably secured to the force-conducting housing part and independently supported on the foundation by brackets and bearing supports.
