Abstract: A method of separating different constituents of a fine fraction that is produced in a prior method for separating a concrete for deconstruction. The method allows the reuse of these different constituents in the production of a new cement and/or of a new concrete, the fine fraction including sand and at least 30% by mass of hydrated cement paste.

Abstract: A crushing machine includes: a frame, a tank, a cone placed inside the tank, the machine further including a device for vibrating the tank with respect to the frame; the machine being characterized in that the device for vibrating the tank includes at least two vibrators which are mounted on the frame, each vibrator being rotated about a longitudinal axis of the frame by a motor, each motor driving the vibrator with which it is associated independently from one another.

Abstract: Disclosed is a method for dissociating different constituents of a heterogeneous artificial material, including the fragmentation of the material in a fragmentation machine by material-bed compression, the machine including at least one vibrator and a system for controlling at least one parameter of the fragmentation force from the speed of rotation of the vibrator and the phase shift angle between at least two vibrators. The control system adjusts a rotation parameter of the vibrators so as to generate a fragmentation force by the machine allowing to at least partially dissociate at least one of the constituents of the material from the other constituents.

Abstract: Method for dissociating different constituents of a heterogeneous artificial material, comprising the fragmentation of the material in a fragmentation machine (1) by material-bed compression, the machine (1) comprising at least one vibrator (8a, 8b, 8c, 8d) and a system (11) for controlling at least one parameter of the fragmentation force from the speed of rotation of the vibrator(s) (8a, 8b, 8c, 8d) and the phase shift angle between at least two vibrators (8a, 8b, 8c, 8d); the method being characterised in that the control system adjusts a rotation parameter of the vibrators (8a, 8b, 8c, 8d) so as to generate a fragmentation force by the machine (1) allowing to at least partially dissociate at least one of the constituents of the material from the other constituents.
