Abstract
The invention relates to a roller mill having a modular construction. In order to permit an increased rated grinding capacity with a limited roller/rocking lever mass and a larger number of rollers, the standards are displaced outwards and the rocking lever axes, relative to the displaced standards, are positioned eccentrically and radially inwards between the grinding table and standards.
