<p>A method for at least partly emptying a crushing chamber (48) formed between an inner crushing shell (18) and an outer crushing shell (12) of an inertia cone crusher (1). The inner crushing shell (18) is supported on a crushing head (16). A central axis (S) of the crushing head (16) will gyrate about a gyration axis (C) with an rpm, for crushing material in the crushing chamber (48). The method comprises - interrupting feeding of material to the crusher (1); - measuring, directly or indirectly, at least one of a position and a motion of the crushing head (16) during an amplitude control period; - comparing the measured position and/or motion with at least one set point value; - determining, based on said comparing the measured position and/or motion to at least one set point value, whether the rpm should be adjusted; - adjusting the rpm when necessary.</p> |
