The present invention relates to a milling device comprising a roll mill (19) having a plurality of rolls (1, 2, 3, 4, 5) for milling a mass (22), imaging means (25, 32) for imaging a surface on at least one of said rolls (1, 2, 3, 4, 5) and for generating a corresponding surface image (26), where said surface imaging means (25, 32) is arranged such the imaged region covers the whole working width of said at least one roll (1, 2, 3, 4, 5), and image processing means (27) for processing said surface image (26). The employment of an imaging means in connection with a roll mill provides a vary flexible and efficient milling system, as the generated image can be processed to fulfill a number of tasks, for example for generating a control signal used to set the operational parameters of the roll mill, for generating a warning signal relating to the deterioration of parts of the roll mill, or for generating an analysis of the state of one of the rolls of the roll mill. |
