  • Crushing plant and method for controlling the same
    Patent number: 8540176
    Abstract: There is described a crushing plant and a method for controlling the same. The crushing plant includes a crusher (1) and a feeding arrangement (3), and is driven by a diesel engine (13). A load value related to the diesel engine is retrieved e.g. by means of a J1939 interface. If the retrieved value exceeds a predetermined threshold value, the control loop of the feeding arrangement (3) is altered. Thereby it can be avoided that the diesel engine (13) stalls, such that continuous operation of the crushing plant may be ensured.

  • Crushing plant and method for controlling the same
    Patent number: 8172167
    Abstract: There is described a crushing plant and a method for controlling the same. The crushing plant involves a gyratory crusher (1) with means for controlling a minimum gap in a crushing chamber, and is driven by a diesel engine (18). A load value is retrieved from the diesel engine e.g. by means of a J1939 interface. If the retrieved value exceeds a predetermined threshold value, the minimum gap is increased. Thereby it can be avoided that the diesel engine stalls; such that continuous operation of the crushing plant may be ensured.
