An example gyratory crusher for comminuting quarry material may comprise a crushing housing having a top and a bottom and a crushing cone having a top and a bottom. The crushing housing may be positioned around the crushing cone such that the crushing housing and the crushing cone form a circumferential crushing space having a crushing throat towards the top and a crushing gap towards the bottom. The crushing throat may be configured to receive quarry material, which, once comminuted, may exit the circumferential crushing space through the crushing gap. The circumferential crushing space may be tapered towards the crushing gap to facilitate this process. The crushing housing may include a crushing wall surface with an undulated surface disposed at least near the crushing throat. Waves of the undulated surface may include wave troughs and wave peaks and extend in a circumferential direction. |
