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.
