ROLLER GROUPS FOR GRINDING DEVICES, GRINDING DEVICES, AND METHODS

The invention relates to roller packages for grinding devices, comprising a first roller, which is maintained by at least one first bearing body, and a second roller, which is maintained by at least one second bearing body. In a first aspect, the first bearing body and the second bearing body are prestressed against each other and comprise stop elements with stop surfaces, the contact of which counteracts a contact of the rollets. The rotational position of the first stop element determines the minimum width of the grinding gap. Also disclosed are grinding devices, methods for operating a roller group and methods for determining the radial force acting between the rollers of a roller group.
