Roller packages (IO) for grinding devices (), comprising a first roll (), which is maintained by at least one first bearing body (), and a second roll (), which is maintained by at least one second bearing body (). 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 rolls (). 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 roll assembly () and methods for determining the radial force acting between the rolls () of a roll assembly ().

Roller groups for grinding devices, grinding devices, and methods

A roller mill () including a housing () having a milling-material inlet (), at least one milling-material outlet (), and at least two cambered rollers (') which are each arranged in the housing () so as to be rotatable about a roller axis (). At least one roller () is assigned a scraper (). The scraper () has a blade () for scraping milling material from a roller surface () with a scraper edge () which extends over an entire length (L) of the blade (), and comprises a holder () with a receiving region (). The holder is arranged in the housing () so as to be tiltable about an axis () parallel to the roller axis. An elastic bearing () is arranged between the blade () and the receiving region ().

Roller mill with a scraper

Roller packages (IO) for grinding devices (), comprising a first roller (II), which is maintained by at least one first bearing body (), and a second roller (), which is maintained by at least one second bearing body (). 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 rollers (II,). 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 (IO) and methods for determining the radial force acting between the rollers (II,) of a roller group (IO).

Top box for grain milling

Roller mill for grain milling

A transmission () for a feed and foodstuff roller mill () with a plurality of rotatably drivable rollers. The transmission () has a bearing housing () in which an input shaft (), a first output shaft () and a second output shaft () are accommodated. The input shaft () and the first output shaft () are arranged perpendicular to one another and the first output shaft () and the second output shaft () are arranged parallel to one another. The input shaft () and the first output shaft () are operatively connected to one another via a bevel gearwheel pair ('), and the first output shaft () and the second output shaft () are operatively connected to one another via a torque transmitting arrangement.
