Abstract: A rolling mill for milling cereals or the like, comprises three roll units, each including two rolls and bearings mounting the rolls for rotation about parallel axes, a housing provided with three outwardly open receiving portions for frontal insertion of the roll units and for supporting the latter after insertion. The receiving portions are vertically spaced from each other with two receiving portions having open ends at one side of the housing and a third of the receiving portions, located between the other two, having an open end at the opposite side of the housing. The rolling mill includes further treating devices in the housing between successive roll units and such treating devices may be constituted by swinging sieves.
