CONE CRUSHER CRUSHING CONE, CRUSHING CONE MANTLE HOLDER FOR A CONE CRUSHER CRUSHING CONE, CRUSHER HAVING A CONE CRUSHER CRUSHING CONE AND METHOD FOR FASTENING AND RELEASING A CRUSHING CONE MANTLE

摘要

The present invention relates to a cone crusher crushing cone comprising: a crushing cone shaft having an external thread; a crushing cone body which is arranged non-rotatably and concentrically around a portion of the crushing cone shaft; a crushing cone mantle which is supported on the crushing cone body; and a crushing cone mantle holder which comprises a nut, which has a central threaded hole with an internal thread which interacts with the external thread of the crushing cone shaft, and a clamping ring which has a central opening and fixes the crushing cone mantle on the crushing cone body. The crushing cone mantle holder comprises at least two externally threaded screws, and the nut has at least two bores, of which each bore has an internal thread and is associated with a specific one of the at least two screws, the internal thread of each bore interacting with the external thread of the specific associated screw in such a way that, due to a rotary movement of the at least two screws relative to the nut, the distance between the clamping ring and the nut can be changed from a first distance to a second distance which is different from the first distance, so that the internal thread of the nut is axially braced against the external thread of the crushing cone shaft.Furthermore, the invention relates to a crushing cone mantle holder, a crusher and a method for fastening a crushing cone mantle to a crushing cone body or releasing it therefrom.
