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 () 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.
