A material crushing cavity structure, comprising:

a first crushing cavity structure for passing through 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, wherein, the first lining plate structure comprises a fixed cone lining plate and a moving cone lining plate, the working faces of the fixed cone lining plate and the moving cone lining plate are stepped curve faces, so that the first crushing cavity forms a first-stage laminating crushing cavity;
a second crushing cavity structure for passing through 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, wherein, the second lining plate structure comprises a concave-convex lining plate structure formed by arranging concave-convex structures on the working faces of the fixed cone lining plate and the moving cone lining plate in the first crushing cavity, so that the second lining plate structure is nested in the first lining plate structure to form a second-stage laminating crushing cavity;
wherein, the first-stage material crushing channel and the second-stage material crushing channel form a continuous material crushing channel.

A method for designing a multi-stage nested material crushing cavity structure, comprising the following steps:

S1) selecting a first crushing cavity structure according to the material characteristics of an input material, wherein, the first crushing cavity structure has a first crushing cavity and a first lining plate structure, the first lining plate structure comprises a fixed cone lining plate and a moving cone lining plate, working faces of the fixed cone lining plate and the moving cone lining plate are stepped curve faces, so that the first crushing cavity forms a first-stage laminating crushing cavity;
S2) selecting a second crushing cavity structure according to the material characteristics of a first-stage material obtained by the input material passing through the first crushing cavity structure, and nesting the second crushing cavity structure in the first crushing cavity structure to form a continuous material crushing channel, wherein, the second crushing cavity structure has a second lining plate structure, the second lining plate structure comprises a concave-convex lining plate structure formed by arranging concave-convex structures on the working faces of the fixed cone lining plate and the moving cone lining plate in the first crushing cavity, so that the second lining plate structure is nested in the first lining plate structure to form a second-stage laminating crushing cavity;
S3) selecting a third crushing cavity structure according to the material characteristics of a second-stage material obtained by the first-stage material passing through the second crushing cavity structure, and forming a multi-stage continuous material crushing channel by the third crushing cavity structure, the first crushing cavity structure and the second crushing cavity structure.
