Abstract
A device for grinding and separating grains, in particular for grinding malt, consisting of at least two roll packages (4, 5, 6) in the form of, with respect to their forces, self-contained units arranged vertically above each other on load-bearing columns (2) of a machine housing (3), and of a pair of screen units (7, 8) oscillating above the lowermost roll package (6) in opposite direction in a horizontal plane and thus with little vibration with respect to the overall device. The screen units are articulated on the machine housing (3) by relatively short levers (27', 29, 31', 33) into which the drive forces for the vibratory equipment are introduced from the center of the machine in such a manner that all rotating parts of the drive (9) are located outside the dusty screen space. In order to increase the screen surface, the screen units (7, 8) are each provided with two continuously inclined screen compartments (10 to 13) equipped with screen frames, all screen frames (14, 14', 15, 15') of a screen unit (7, 8) being firmly clamped on all sides or released for the pulling out thereof by the actuation of a single closure flap.
