摘要： Provided is a sintering apparatus. The sintering apparatus includes a plurality of sintering trailers movably disposed along a moving path and in which a raw material is inserted therein, an ignition furnace disposed above the sintering trailers to spray flames to a top surface of the raw material, a wind box provided in plurality under the sintering trailers along the moving path to suction air downward from the sintering trailers to sinter the raw material, a cooler disposed on one side of the moving path to supply a cooling gas to a sintered ore discharged from each of the sintering trailers, and a first circulation part connected to the cooler to supply at least one portion of the cooling gas supplied to the raw material to an upper portion of the sintering trailer to control a combustion process of the raw material or improve combustion efficiency, thereby improving quality and productivity of the raw material.
