<p>A method and a system for monitoring a gyratory or cone crusher (200) comprises a measuring apparatus (215) suitable for measuring load of the crusher; a first element (212) to be placed on a main shaft of the crusher and a first detector (213) suitable for detecting the first element which first detector provides a trigger starting a measurement revolution; and at least one second element (208,209,210) to be placed on a drive shaft of the crusher and a second detector (211) suitable for detecting the second element which second detector provides a trigger corresponding to a certain rotational position of an inner blade (201) of the crusher. The system comprises an output to a screen for presenting the loads or averages of the loads corresponding to rotational positions of the inner blade of the crusher. Detections of the monitoring system can be used for controlling and monitoring a crushing event for example by changing an area or a location of a feed opening of the crusher (200).</p> |
