摘要： Apparatus for the recovery of a heterogeneous mass constituted by two or more plastics materials has a cold mixing stage in which the heterogeneous mass, previously chopped, is subjected to a thorough mixing so as to give a uniform mixture. This treatment is performed in a screw mixer (100) whose central region (102) has helical thread sections (104) of opposite hand from one another. The mixed homogeneous mass thus obtained is then subjected to a heat treatment in another screw conveyor in which the core has a section of gradually increasing diameter followed by a sharp discontinuity intended to encourage degasification of the material subjected to the heat treatment.

摘要： I@ Following an initial operation possibly required for separation from other types of refuse, waste plastics materials are triturated or crushed and cold-mixed. The triturated and mixed wastes undergo a first heating stage at a first temperature, with a view to obtaining a mass in an initial state of plastification. This mass subsequently undergoes a second heating stage at a second temperature, generally different from said first temperature, until there is obtained thereform a homogeneously melted mass. The apparatus comprises a generally tubular housing (21) carrying at one end thereof a triturating device (2) within which the wastes are reduced to fragments and cold-mixed. The triturating device (2) comprises a toothed rotor (9) fitted onto a rotary element (16) rotatably mounted within the housing (21) and provided with thrust surfaces for the material with a helicoidal development (24, 25, 26, 28). The hub (10) of the triturator (2) is provided with apertures (15) which permit the triturating material to penetrate radially into this hub (10), so as to be brought into contact with the thrust surfaces of the rotary element (16) which functions as a mixing member. On at least one longitudinal portion (19) of the rotary element (16), the thrust surfaces for the material are defined by angular screw-threaded sectors (25, 26) arranged according to at least two oppositely directed helicoidal trajectories.
