ABSTRACT:
A method for controlling a crushing gap width of a gyratory crusher of the kind including a crusher head is disclosed. The crusher head of the crusher is driven by a power unit and is positionally adjustable in relation to a crusher shell by a hydraulic motor. The hydraulic motor moves the crusher head of the crusher, thereby adjusting the crushing gap width. A power consumption of the crusher, pressure load on the crusher head, and the width of the crushing gap are determined continuously. The crushing gap width is controlled by being adjusted when the gap width is, above a pre-determined minimum gap width value, substantially in accordance with a control function which depends on both the power consumption and the pressure load, and which is so selected as to provide an intended crushing effect the material being crushed.
