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.

In case of retrofitting a sinter cooler (1) comprising a rigid grate (5) for holding sinter material, the method for retrofitting further comprises removing the rigid grate (5) before installing the lamella grate (10).

A heat treatment system includes heating chambers configured to perform heat treatment on objects to be treated, and a conveyance device configured to load each of the objects to be treated into the heating chambers, unload the object to be treated from the heating chambers, and convey the object to be treated under an oxygen-free atmosphere, wherein the conveyance device includes a cooling device configured to perform cooling treatment on the object to be treated.

A cooling apparatus of hot briquetted iron is proposed. The cooling apparatus includes a cylindrical rotary body rotating while being inclined such that an outlet section through which cooled hot briquetted iron is discharged faces upwards, and including a water-level control plate formed under a hot-briquetted-iron charging section to retain a predetermined coolant; a blade formed along an inner circumferential surface of the rotary body to guide the hot briquetted iron introduced therein towards the outlet section; and a coolant spray module including a plurality of spray nozzles that differentially control an amount of the coolant sprayed inwards from the outlet section. The hot briquetted iron is primarily cooled by retained coolant, is guided by the blade, and is secondarily cooled by the coolant spray nozzles, thus maximizing cooling efficiency of the hot briquetted iron during a cooling process and thereby minimizing coolant consumption.

The present invention discloses a cooler for cooling particulate material which has been subjected to heat treatment in an industrial kiln, such as a rotary kiln for manufacturing cement clinker.
