Abstract

Roll press or mill with two adjacent rolls (2, 4) with cooperating compression surfaces, mounted in bearing housings located between an upper and lower box girder, one roll being adjustable, with a material feed system with at least one fill chamber (6) with walls (22, 24) parallel to the roll axes and extending into the roll gap (8) and with apparatus to eliminate the air entering the roll gap with the material, provided with air admission holes in the region of the roll gap leading into an air collection chamber connected with air outlets. On each side of the fill chamber walls, parallel to the axes, chambers (16, 18) extend essentially over the breadth of the compression surfaces of the rolls and are closed at their ends. The chambers are each connected to the roll gap by a passage (28, 30) formed between the compression surfaces at the perimeter of the rolls and the lower end of the walls adjacent to the walls of the filling chamber. The chambers (16, 18) are provided with air outlets (34, 36).
