The instant inven- tion furthermore relates to the separation of a light and a heavy fraction obtained during shredding, further to grinding of the light fraction in a grinding device. which is preferentially designed as a rolling mill and to the liquefaction of the propellant liberated.
Procédé de recyclage de réfrigérateurs. On enlève (9) les parties aisément démontables telles que plateaux de verre, commutateurs, câbles, lampes et similaires, on retire (9) le mélange huile/agent réfrigérant du circuit réfrigérant, on enlève (10) le(s) compresseur(s) et on effectue un déchiquetage (11) du réfrigérateur partiellement démonté. Le gaz d'expansion dégagé par le matériau isolant passe à travers un filtre à charbon actif. L'invention concerne également la séparation des matières déchiquetées en une fraction légère et en une fraction lourde. La fraction légère est broyée (12) davantage dans un autre broyeur, de préférence un broyeur à meules, et le gaz d'expansion dégagé est liquéfié.
