Le système de classement et de recyclage de déchets comprend un appareil de broyage de déchets et un bassin de séparation de déchets. Un composant de déchiquetage et de broyage est disposé dans un boîtier de l'appareil de broyage de déchets. Un orifice de décharge et un orifice de drainage sont disposés à l'arrière du boîtier. Les déchets sont délivrés en continu dans le boîtier et simultanément, une quantité appropriée d'eau est ajoutée ; le composant de déchiquetage et de broyage dans le boîtier déchiquète, broie, extrude et déchire les déchets dans un processus tel que les déchets tournent avec le boîtier ; et les déchets se déplacent à l'extrémité arrière du boîtier dans le processus de rotation, puis les articles lourds sont déchargés depuis l'orifice de drainage, et les articles légers se déversent par l'orifice de décharge. L'appareil de broyage de déchets de la présente invention n'a pas besoin d'effectuer un tri primaire des déchets lorsque les déchets sont broyés ; les déchets peuvent être directement délivrés dans le boîtier de l'appareil de broyage, et l'ensemble des déchets sont broyés, et en conséquence, l'efficacité du traitement des déchets peut être améliorée et le coût peut être réduit. Après l'entrée dans le bassin de séparation, les déchets broyés sont soumis à une séparation en fonction des différentes densités, de sorte que les déchets soient séparés. Dans la présente invention, un plus petit nombre de dispositifs est nécessaire, le coût est faible, et l'effet de séparation est satisfaisant.
