An air-cooled electric motor installation comprising a least an electric motor (2) connected to a primary user (14), and means (7) for generating a cooling air stream for cooling said motor (2), wherein with said motor (2) is associated a pipe (15) which receives the cooling air leaving the motor (2) and conveys said cooling air to a secondary user (10) in which said cooling air is further exploited. Said secondary user (10) is formed, for example, by a falling path of a conveyor belt or separation screen (14) delivering a crushed rubble mixture stream (13) to be separated in light (11) and heavy (12) components.
