A method for crushing and sorting large-sized garbage, applicable to a large-sized garbage crushing and sorting production line according to any one of claims 1 to 4, characterized in that: The following steps are involved: S1: adding waste materials to a metal chain conveyor (1) and transporting them to a double-shaft shredder (2) for shredding; S2: The transported material is then transported to a four-axis shredder (4) for secondary shredding, where the material is shredded to 60 mm and then enters a vibrating screen (5); S3: The vibrating screen (5) flattens the material and then transports it to the Z-type sorting system (7); S4: The material is transported into the Z-type sorting system (7) and is spirally transported from top to bottom. During the transportation process, it is dispersed and stirred so that the belt magnetic separator (14) can separate the metal inside. S5: the transported material is further transported to a briquetting machine (10) for briquetting and granulation; S6: Light materials generated during processing are collected by providing negative pressure pumping.
