The conical mantle has an armpit groove for receiving a slip ring. The armpit groove is covered by the conical mantle with an armpit thickness L. Fretting wear is reduced by dimensioning the crusher head so that a ratio of the head diameter Dto the nominal interference fit diameter Dis most 2.5; and a ratio of the head diameter Dto the armpit thickness Lis at least 10.5.
