The invention relates to a roll mill having at least one pair of grinding rollers bearing against a substantially horizontal surface of a grinding table which is rotatable about a vertical axis. The rollers are mounted at one end of a roller support the opposite end of which is guided by guide lugs slidable vertically in guides and linked to the roller support by a tension rod. In order to achieve particularly smooth running of the grinding rollers on the grinding surface, the guides and the guide lugs lie approximately at the level of the grinding surface.
