Choosing the right construction materials is crucial to improving project quality and extending service life.

[0003] During the highway construction process, some raw materials (such as stone, asphalt mixture and carbon slag, etc.) need to be crushed to meet specific technical requirements or facilitate subsequent processing and use. At present, a crushing device is usually used to crush the raw materials. First, people pour the raw materials into the crushing device, and then the raw materials are crushed by the crushing roller to disintegrate and fragment the raw materials. Then, the raw materials are screened through the sieve plate, and the unqualified raw materials are screened and poured into the crushing device again for crushing. However, the existing crushing device requires manual removal of unqualified raw materials and then pouring them into the crushing device for secondary crushing, which is relatively troublesome.

[0004] In summary, there is an urgent need for a highway construction raw material crushing device that is convenient for secondary crushing of unqualified raw materials to solve the above problems. Utility Model Content
