Abstract

Des pièces en plastique qui, du fait de la température des surfaces métalliques placées en contact avec elles, deviennent adhésives auxdites surfaces auxquelles elles se soudent, peuvent être séparées d'une masse conglomérée, notamment d'une masse conglomérée d'ordures ménagères broyées. Les surfaces chauffées de séparation, après contact intime avec la masse conglomérée sont retirées de cette masse, entraînant ainsi les pièces en plastique qui adhèrent auxdites surfaces. Après quoi, les surfaces métalliques chauffées sont raclées. De préférence, les régions de surface chauffées sont prévues sur les faces intérieures d'un tambour rotatif (24) incliné, dans lequel est introduite la masse conglomérée (5).
