ABSTRACT:
The invention relates to a material bed roller mill having two rollers (1, 2) which are rotatably supported in a machine frame (3) and driven in opposite directions and whose roller gap, which is charged from above with the grinding material to be comminuted, is delimited at its ends during the operation of the roller mill by a grinding material guide plate (5) which can be removed from its operating position, whereina) the grinding material guide plate (5) is displaceable in an upward direction and away from the end of the roller gap to such an extent relative to its operating position that the rollers (1, 2) can be removed from the machine frame (3) in the horizontal direction;b) during that displacement movement, the grinding material guide plate (5) is guided by guide bodies along an arc-shaped guide andc) in the operating position, the grinding material guide plate (5) is supported towards the outside against the forces exerted by the grinding material by support members which are connected pivotably to the grinding material guide plate.
