  • Method and device for controlling the operation of a gyratory crusher
    Patent number: 8540175
    Abstract: A gyratory crusher comprises a first crushing shell mounted on a crushing head, and a second crushing shell mounted on a machine frame, a crushing gap being formed between said first and second crushing shells. 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.
