    摘要: The embodiments of the present invention provide a crushing cavity structure for the technical field of crushing cavities of cone crushing equipment. The crushing cavity structure comprises: a first crushing cavity structure for through-crushing an input material having a first material characteristic, the first crushing cavity structure has a first crushing cavity and a first lining plate structure that match the first material characteristic, and the first crushing cavity and the first lining plate structure form a first-stage material crushing channel; a second crushing cavity structure for through-crushing a first-stage material having a second material characteristic, the first-stage material is obtained by the input material passing through the first-stage material crushing channel, the second crushing cavity structure has a second crushing cavity and a second lining plate structure that match the second material characteristic, and the second crushing cavity and the second lining plate structure form a second-stage material crushing channel.
