A gyratory crusher comprises a first crushing shell (4) mounted on a crushing head (3), and a second crushing shell (5) mounted on a machine frame (16), a crushing gap (6) being formed between said first and second crushing shells (4, 5). A method of controlling the operation of said crusher comprises measuring a parameter being representative of the stresses to which the crusher is exposed during the crushing of material, determining an average value of said parameter, determining a deviation value of said parameter, calculating a peak value based on said average value and said deviation value, comparing said peak value to a reference value, and controlling the operation of the crusher in view of said comparison between said peak value and said reference value. |
