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: 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 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: An accelerated carbonatation method including the following steps: a) providing recycled concrete granulates with a grain size smaller than or equal to a value V1 being between 1 mm and 6 mm, in other words a 0/V1 sand; b) performing on the 0/V1 sand a separation step by defining a granulometric cut of a determined value V2 being between 0.1 mm and 0.2 mm so as to obtain: a 1st fraction whose grain size is less than V2, and a 2nd fraction whose grain size is between V2 and V1; c) subjecting the 2nd fraction to an accelerated carbonatation step in a dynamic carbonator so as to obtain carbonated recycled concrete granulates. Also, a method for valorizing concrete wastes and industrial gaseous discharges implementing the accelerated carbonatation method, in particular the gaseous discharges of a cement plant.

Abstract: Method for repairing the teeth of a ring gear and a machining device unit including a frame and a moving part bearing a cutting member movable along multiple axes with respect to the frame, the method including: attaching the machining device to the ring gear by tightening parts rigidly attached to the frame of the machining device, engaging with the flanks of the ring gear, defining the position of the machining device with respect to the tooth to be machined by abutting on the flank of a reference tooth, the flank being situated, with respect to the summit of the reference tooth, in the direction opposite the flank of the tooth to be machined, the reference tooth being the tooth to be machined or an immediately preceding tooth, performing the machining of the flank of the tooth to be machined by control of the cutting member per predetermined machining operations.

Abstract: Disclosed is a method for producing sintered material from organic raw materials, implemented in an apparatus comprising, a cyclone preheater, a rotary furnace and a grate cooler, and in which the raw materials are preheated in the cyclone preheater, the preheated material is calcined and sintered in the rotary furnace, and the calcined materials are cooled by blowing cooling air in the grate cooler, producing hot air. The hot air is separated into three upstream-to-downstream fractions, the three hot air fractions being at decreasing temperatures. The first air fraction acts as combustion air in at least the combustion zone of the rotary furnace and/or of the potential precalciner of the apparatus. The second air fraction is greater than the combustion air needs to produce energy. The third air fraction is directed at least in part to the combustion zone of the apparatus, providing combustion air with the first air fraction.
