  • Method for monitoring condition of bearings of a crusher, and a crusher
    Patent number: 6877682
    Abstract: Malfunctions of sliding bearings of cone crushers used in crushing stone are anticipated by providing sensors in connection to bearing parts, by means of which sensors it is possible to observe increases in friction forces. A beginning bearing damage can be detected by means of sensors at such an early stage, that extensive damage to bearings and to other parts of the crusher can be prevented.

  • Method for monitoring condition of bearings of a crusher, and a crusher
    Publication number: 20040050983
    Abstract: Malfunctions of sliding bearings of gyratory crushers used in crushing stone are anticipated by providing sensors in connection to bearing parts, by means of which sensors it is possible to observe increases in friction forces. A beginning bearing damage can be detected by means of sensors at such an early stage, that extensive damage to bearings and to other parts of the crusher can be prevented.
