  • Roller mill
    Patent number: 4147308
    Abstract: A vertical roller mill is disclosed for grinding material. The roller mill includes a rotatable grinding table at least one grinding roller resting upon the grinding mill, a pressure frame secured to the grinding roller and a housing which surrounds these elements. A guide mechanism pivotally connected between the pressure frame and the housing resiliently restrains movement of the pressure frame with respect to the housing and thereby reduces the transmission of forces from the pressure frame to the housing.
