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 distribution metering device () for a roller mill which includes a housing () with at least one grinding stock inlet (), at least one grinding stock outlet (), and a feed roll () which is arranged in the housing () for metering grinding stock into a grinding gap of the roller mill through the grinding stock outlet (). The feed roll is rotatable about a feed roll axis (SA). A conveyor shaft () is arranged in the housing () for distributing grinding stock along the feed roll (). The conveyor shaft is rotatable about a conveyor shaft axis (FA). The conveyor shaft axis (FA) is substantially parallel to the feed roll axis (SA), and a first fill state sensor () is arranged in the housing () for ascertaining a first grinding stock fill state of the housing ().

An intake arrangement () for a roller mill which includes a storage container (), a force transducer () arranged on the storage container (), a level sensor () arranged on the storage container () for determining when a ground material level (B) is reached in the storage container (), and a control unit (). The control unit () is designed to determine a first fill level (A) of the storage container (), from a weight force (EG) determined by the force transducer (), and to determine a characteristic fill level curve (K), based on the determined first fill level (A) and the fill level (B) determined by the level sensor ().

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 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

A device for comminuting bulk material grains (K) having a first element, designed as a rotor having a cylindrical circumferential surface with a first surface () and a first receiving portion (), and a second element designed as a shear strip () having a second surface () and a second receiving portion (), and a supply unit. The first and the second surfaces () lie parallel to and face one another. The first and second elements are relatively movable between first and second positions (P, P) in a plane of the first and the second surfaces (). In the first position (P), the first and second receiving portion () communicate with one another, via a passage () forming a receptacle, in which the bulk material grain (K) can be positioned, and, upon moving to the second position (P), a cross section of the passage () is narrowed.

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.

A roller mill () for grinding material, an aspirating assembly (') and a method of retrofitting an existing roller mill. The roller mill () contains a grinding space (&#x2032;) for grinding material, a separating wall () separates the grinding space from an aspiration space (&#x2032;). At least one aspiration opening (), is formed in the separating wall () through which aspiration air can flow due to a pressure difference between the aspiration space and the grinding space. The roller mill () has a closing element () for opening and closing the aspiration opening (). The closing element () is in or moves into an opening position (O), which opens the aspiration opening (), when the pressure difference exceeds a threshold value, and is in or moves into a closing position (S), which closes the aspiration opening (), when the pressure difference falls bellow the threshold value.

Roller mill, aspirating assembly, and method for retrofitting a roller mill

A method of producing flour and/or semolina by raw material being fed into a feed opening of a roller press. The milling gap of the roller press is fixed, or damping of at least one of the rollers with respect to the lateral deflection is set, such that a first subset of the fill containing finer milling material forms a packed particle fill in the milling gap. In addition, the setting is carried out in such a way that individual particles of a second subset of the fill containing coarser milling material are in contact with the first roller and the second roller of the roller press. Subsequently, the bulk material is milled into milled product in the roller press () and the milled product is discharged through a discharge opening.
