ABSTRACT:
For cone crushers comprising an eccentrically-driven crushing cone, it is necessary to provide a labyrinth seal between the inwardly disposed eccentric drive and the crushing cone, the upper seal half thereof being connected to the crushing cone and the lower seal half thereof being connected to the eccentric drive. A new labyrinth seal is essentially distinguished in that helically extending fluids are provided on at least one wall of a cylindrical ring of the lower and/or upper seal half. It is thereby achieved that the slight air flow constantly emerge from the sealing gap and a penetration of dust into or, respectively, through the sealing gap is reliably prevented.
