Method for recycling and treating spoil material and installation for implementing this method

摘要

The method involves progressively introducing vein of materials (12) in an enclosure (6) by gravity, and adding an adjuvant to the materials in the enclosure. The materials are sprayed and mixed with the adjuvant to form a mixture by using a blade rotor (7), where spraying and mixing of the materials are performed by permanently maintaining a filling level of the materials in the enclosure. The mixture is evacuated through an opening placed at an interior downstream part (13) of the enclosure, where rotation of the rotor permits excavation of the mixture through the opening. An independent claim is also included for an installation for treating and recycling earthwork debris to obtain grinds constituted by a mixture of materials issued from the debris with an adjuvant.
