Abstract:
A material bed roll mill omprising:first and second rolls (2, 3) which are rotatably mounted in a machine frame (6), said first and second rolls being driven so that they rotate in opposite directions and pressed against one another with a pressing force of more than approximately 50 MPa and up to approximately 400 MPa; a replaceable outer wear protection casing (2b, 3b) mounted on each end of the first and second rolls; at least two (first and second) bearing jewels (8, 7) for each of the first and second rolls (2, 3), said bearing jewels (7, 8) being disposed in the machine frame (6) and are axially spaced from one another; and first and second roll shafts (4, 5) each projecting axially on one side and is rotatably mounted in the corresponding bearing jewels (7, 8) for rotating the first and second rolls; wherein said first and second rolls (2, 3) are mounted at one end in the machine frame (6) each having only one roll shaft (4, 5); and wherein the first bearing jewel (8) adjacent to the first or second roll is retained as a bearing jewel which is displaceable transversely with respect to an axis of rotation (2a, 3a) of the roll, while the second bearing jewel (7) which is remote from the roll is disposed so as to be stationary; and wherein each of the first and second roll shafts (4, 5) is disposed so as to be pivotable in the region of the second bearing jewel (7) about a pivot axis (7a) extending transversely with respect to the axis of rotation (2a, 3a) of the roll.
