    Abstract: Disclosed is a method for treating fly ash containing an initial carbon concentration to obtain ash containing a predetermined final carbon concentration less than the initial concentration, the method including: —a step of granulometric separation of the ash into at least two fractions, a coarse traction and a fine fraction, the coarse fraction having a granulometry greater than the fine fraction; —a step of extracting carbon from the ash; a method wherein the extraction step is subsequent to the separation step, the extraction step being implemented solely on the coarse fraction, by electrostatic separation, the method including a step of drying the ash during which the temperature of the ash is above 60° C.

    Abstract: A method for producing calcined clay having desired colour characteristics. The method includes: a step of calcining a clay in a calcination furnace, the calcination step being carried out under stoichiometric or oxidising conditions, and a step of reducing iron (III) oxides present in the calcined clay in a reduction system separate from the calcination furnace, this reduction step being carried out by injecting a reduction gas, containing hydrogen atoms and placed in direct contact with the calcined clay.

    Abstract: A mill for crushing a bed of materials by compression includes: a horizontal-axis cylinder the interior wall having a runway track for a crushing roller placed inside the cylinder, a unit rotating the cylinder at a speed that spins the material outward, the crushing roller, a unit for pressing the crushing roller against the runway track of the cylinder, an inlet for supplying material for crushing at one end of the cylinder and an outlet for crushed material at the other end, a unit for controlling the movement of the material so it travels over only a fraction of the length of the cylinder in each revolution and passes between the cylinder and the roller several times before reaching the outlet. The runway track is followed by a downstream lip opposing material flow, downstream of the crushing roller in the direction in which the material travels.

    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.
