Abstract
Roller packages (IO) for grinding devices (70), comprising a first roller (II), which is maintained by at least one first bearing body (13), and a second roller (12), which is maintained by at least one second bearing body (14). The first bearing body (13) and the second bearing body (14) are prestressed against each other and comprise stop elements (17, 19) with stop surfaces (18, 20), the contact of which counteracts a contact of the rollers (II, 12). The rotational position of the first stop element (17) determines the minimum width of the grinding gap. Also disclosed are grinding devices (70), methods for operating a roller group (IO) and methods for determining the radial force acting between the rollers (II, 12) of a roller group (IO).
