  • Adjustable crusher
    Patent number: 5779166
    Abstract: The application presents an adjustable cone crusher which has a hydraulic cylinder-plunger-combination (15, 4) for adjusting the setting and supporting a main shaft at its bottom end. The combination contains a bypass channel (21), through which the pressure medium escapes from the cylinder when the combination has been extended by a certain distance. In this way the crushing cone is prevented from rising too much upwards.
