Background The construction waste is construction waste generated in engineering due to artificial or natural reasons, such as dregs, waste concrete, waste masonry and other wastes generated in the production activities of construction industries such as removal, construction, decoration, repair and the like. At present, there are many construction waste crushing and recycling treatment apparatuses on the market, but general construction waste crushing and recycling treatment apparatuses have the following problems when crushing construction waste in a wet state: 1. Moist construction waste (especially containing fine particles such as soil, gypsum, mortar and the like) is easy to bond into clusters, and blocks a screen or a discharge hole of a pulverizer, so that the discharge efficiency is reduced, and frequent shutdown cleaning is required. 2. The moist construction waste can adhere to the surfaces of key components such as a crushing cavity, a rotor, a hammer head and the like, so that the effective working space is reduced, the crushing effect is affected, and meanwhile, the rotor is blocked due to viscous materials, so that motor overload or transmission system failure is caused. 3. Because of the possible presence of chlorides (e.g., sea sand), alkaline substances (e.g., cement) or chemical additives in the construction waste, the wet environment can accelerate corrosion of the metal parts of the pulverizer. 4. The wet construction waste needs more energy when being crushed, so that the load of a motor is increased and the energy consumption is increased, and the resistance of the wet construction waste in the crushing and conveying processes is increased and the processing capacity is greatly reduced due to poor fluidity.
