[0002] The disposal of construction waste is an important environmental issue, and a series of measures need to be taken to ensure that the waste is properly handled and reduce the negative impact on the environment.

[0003] The treatment process of construction waste generally includes the following steps:

[0004] Sorting: Since construction waste is mixed with a wide variety of waste, it needs to be sorted first to avoid malfunction of processing equipment;

[0005] Crushing: The sorted waste will be crushed, including coarse crushing, medium crushing, fine crushing and other processes, and the output and finished product particle size will be adjusted according to demand;

[0006] Screening: The crushed raw materials will be screened according to different particle sizes for subsequent use.

[0007] In order to deal with construction waste, special construction waste treatment equipment is also needed, including crushing equipment, sorting equipment, cleaning equipment and recycled aggregate production lines, etc. These equipment can effectively crush, sort and clean construction waste, and realize the resource reuse of construction waste.

[0008] However, the crushing equipment in the existing technology, when crushing construction waste, often uses two crushing rollers with crushing teeth to crush the construction waste by rolling and applying force to each other. However, the crushing effect of the construction waste is often poor due to the low density of the crushing teeth, while the high density of the crushing teeth makes it easy to be damaged. Therefore, for the crushing of construction waste, it is necessary to sort it in advance, which affects the processing cost of the construction waste. In view of this, we propose a construction waste treatment device. Utility Model Content
