Description

Technical Field

[0001] The utility model relates to the technical field of garbage disposal, in particular to a crusher. Background Art

[0002] With the acceleration of industrialization and urbanization, the construction industry has also developed rapidly. The amount of construction waste generated is increasing day by day. The management of construction waste is difficult. It not only occupies a large amount of land, but also pollutes the environment. Therefore, with the progress and development of society, the regeneration and recycling of construction waste resources has become a topic of increasing concern.

[0003] After crushing, construction waste can be used as recycled aggregate, road filler, brick making raw material, etc.

[0004] It has been found in actual use that the existing crushers have the following deficiencies when crushing construction waste:

[0005] After the construction waste is put into the crushing structure, it accumulates on the crushing structure. The crushing structure rotates continuously to crush the construction waste in the gap of the crushing structure. However, the construction waste is in passive contact with the crushing structure, and the friction is small due to the single force point. The construction waste is constantly stirred and rolled on the crushing structure, resulting in a slow crushing efficiency of the construction waste, which affects the processing speed of the construction waste.

[0006] In addition, due to the irregular shape of construction waste, direct crushing of the waste is easy to cover the crushing structure, resulting in a short contact time between the crushing structure and the waste, and the contact area cannot be guaranteed, which easily leads to crushing dead angles, resulting in incomplete crushing. Some uncrushed parts are easy to leak directly from the crushing structure, resulting in incomplete crushing and uneven crushing size.

[0007] Therefore, the present application provides a pulverizer to meet the needs. Utility Model Content

[0008] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a pulverizer.
