To produce flour and/or semolina, raw material is 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 (9) and the milled product is discharged through a discharge opening.

The present invention is related to an inlet arrangement for a grinding machine, preferably a roller mill, comprising a main sensor, preferably a force sensor, and an additional sensor, preferably a level sensor, that extends into the storage container to a level that corresponds to the level where the main sensor is provided, and a control unit which is configured to generate, from the values determined by the main sensor and the additional sensor and from a setpoint value, an output signal to control the flow of the milling material out of the storage container. The present invention is further more related to said control unit, a grinding machine, preferably a roller mill, comprising said inlet arrangement, and to a method for determining and controlling the level of milling material in a storage container for milling material of a grinding machine, preferably a roller mill, involving the above inlet arrangement.

A device, system and method, according to various embodiments, for processing a granular material to produce a flowable granular composition having a flowable form, without the addition of an additive. The granular material is passed between multiple rotating screws, the particles within the granular material are broken down, and moisture within the granular material is released until it assumes a condition such that the flowable granular composition will not substantially clump or form bridges when the flowable granular composition is in a humid environment, in a subsequent process, during transport or during storage.

A roller mill (10) for grinding material, an aspirating assembly (23; 23) and a method of retrofitting an existing roller mill. The roller mill (10) contains a grinding space (11, 11) for grinding material, a separating wall (17) separates the grinding space from an aspiration space (21, 21). At least one aspiration opening (13), is formed in the separating wall (17) through which aspiration air can flow due to a pressure difference between the aspiration space and the grinding space. The roller mill (10) has a closing element (14) for opening and closing the aspiration opening (13). The closing element (14) is in or moves into an opening position (O), which opens the aspiration opening (13), when the pressure difference exceeds a threshold value, and is in or moves into a closing position (S), which closes the aspiration opening (13), when the pressure difference falls bellow the threshold value.

A system and method for flaking. The system includes a stationary roller, and moveable roller, and an adjustable fixator applying tension between the stationary and moveable rollers. The fixator includes a pressure transducer and a linear indicator. The transducer and indicator allow the fixator to read pressures and make fine adjustments to the fixator to obtain a desired gap between the two rollers.
