摘要:
A dust seal for a cone crusher or gyratory crusher and a cone crusher or gyratory crusher are provided, wherein the crusher includes a stationary part having a dust collar, and a crusher head which is supported so as to be rotatable relative to the stationary part in a crushing direction of rotation and in an idling direction of rotation which is opposite to the crushing direction of rotation. The dust seal has a crusher head contact portion configured for directly or indirectly contacting the crusher head, and a dust collar contact portion configured for directly or indirectly contacting the dust collar crusher head. The dust seal is configured to impart a frictional force between the crusher head and the dust seal via the crusher head contact portion, and/or between the dust collar and the dust seal via the dust collar contact portion upon rotation of the crusher head at least in the idling direction of rotation. The invention is characterized in that the dust seal is configured so that the frictional force imparted by the dust collar contact portion and/or the crusher head contact portion is higher upon rotation of the crusher head in the idling direction of rotation than upon rotation of the crusher head in the crushing direction of rotation.
