System and method for characterising grinding material in a roller mill

The invention relates to a system and method for characterisation of a particle flow, for example, for characterisation of material for milling, in particular for milled cereals, in a roller frame with a roller passage (6) formed by a pair of rollers (2, 4) whereby the system comprises a withdrawal means (8) after the roller passage (6) for removal of a milled material sample (1) from the milled material flow exiting the roller passage (6), a presentation section (10) for conveying and presenting the taken milled material sample (1), a recording means (12, 24) for recording the milled material sample (1) passing through the presentation section (10) and an analytical means for analysis of the recorded milled material sample (1).
