To provide a method for recovering resin granular matter capable of peeling a metal film from not only a conventional metal film-applied resin material using ABS or the like as a base material but also a metal film-applied resin material using polypropylene having high adhesion as a base material.

The method for recovering the resin granular matter C includes a grinding and separating process using a grinder 20, which has a fixed blade and a rotary blade and grinds the metal film-applied resin material A by the shearing force due to both blades, to perform grinding and the separation of the metal film D and the resin granular matter C.
