Abstract
A crusher system includes a gyratory crusher, which has a crushing head, on which a first crushing shell is mounted; a frame, on which a second crushing shell is mounted; and a driving device, which is arranged to cause, by means of a rotating eccentric, the crushing head to execute a gyratory movement for crushing material. The crusher system includes a device for generating a signal that indicates the current tendency of the crushing head to spin; a device arranged to establish, based on the signal, a maximum allowable rotational speed for the eccentric; and a device arranged to adapt the rotational speed of the eccentric to a rotational speed that is lower than the maximum allowable rotational speed.
