These wastes usually need to be processed and sorted for subsequent recycling and reuse. Concrete and bricks: including crushed stone, concrete, gypsum, asbestos cement boards, etc.

[0003] Asbestos cement board is a common building material, which is a mixture of cement, asbestos and other fibers. It can be used for indoor and outdoor decoration and structural materials such as walls, ceilings, roofs, partitions, etc.

[0004] In the process of recycling asbestos cement boards, it is necessary to crush larger asbestos cement boards into multiple small pieces to facilitate the transportation and storage of asbestos cement boards. Since asbestos cement boards contain harmful substances such as asbestos, asbestos fiber dust will be generated during the crushing process of asbestos cement boards. However, when crushing asbestos cement boards, it may be inconvenient to spray water or water may remain in the crushing box, so it may not be possible to pre-wet or wet-crush the asbestos cement, and then it is impossible to moisten the dust formed during the crushing process, which increases the flying ability of asbestos fibers.
