Cone crusher crushing cone, crushing cone casing holder for a cone crusher crushing cone, crusher with a cone crusher crushing cone and methods for attaching and loosening a crushing cone casing
The present invention relates to a cone crusher crushing cone with a crushing cone axis with an external thread, a crushing cone body which is arranged non-rotatably and concentrically around a portion of the crushing cone axis, a crushing cone shell, which is supported on the crushing cone body, and a crushing cone shell holder, which has a nut with a central threaded hole with an internal thread , which cooperates with the external thread of the crushing cone axis, and comprises a clamping ring which has a central opening and fixes the crushing cone casing on the crushing cone body, wherein the crushing cone casing holder comprises at least two screws with an external thread and the nut has at least two bores, each of which has an internal thread and one of the at least two screws is assigned in each case, the internal thread of each bore cooperating with the external thread of the respectively assigned screw in such a way that as a result of a rotational movement of the at least two screws relatively z u of the nut, the distance between the clamping ring and nut can be converted from a first distance to a second distance which is different from the first distance, whereby the internal thread of the nut is axially braced against the external thread of the breaking cone axis. The invention further relates to a crushing cone jacket holder, a crusher and a method for attaching or detaching a crushing cone jacket to or from a crushing cone body.
