Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a multi-stage compound crusher. Background Art

[0002] Material crushing is an essential process in the production of products across numerous industries, including mining, building materials, chemicals, and metallurgy. A single crusher can only achieve limited results, so multi-stage compound crushers are often used to maximize the degree of material crushing. Compound crushers offer highly efficient crushing capabilities for hard materials such as shale, glass, ceramics, bluestone, and metal ores, and are particularly widely used in the production of manufactured sand and gravel, as well as metal ores.

[0003] After searching, the patent publication number CN220547015U discloses a patent named a multi-stage compound crusher. The technical problem to be solved is that the crushing is generally performed in a single time, and the crushed materials will be of different sizes, and the crushing quality and efficiency will deviate, which will lead to the inability to use the materials of different sizes in the later stage. Compared with the existing crusher, when the crusher is put into use, the material is first put into the feed port, and the first motor is started during the period. Through the meshing principle, the first crushing roller will crush the material for the first time, and then the second motor is started. Through the same meshing principle, multiple second crushing rollers will crush the fallen material again in a way of receiving the material, thereby achieving the effect of multi-stage efficient crushing; but there are still the following disadvantages that need to be solved: it is inconvenient to adjust the fineness of the material.
