PROBLEM TO BE SOLVED: To provide a method for producing a pellet by which increase in production of pellet or increase in ration of high crystal water ore can surely be achieved.SOLUTION: In a great kiln system production method of iron ore pellet where an iron ore pellet is heated sequentially in a drying chamber 3, a water separation chamber 4 and a preheat chamber 5 while being moved on a traveling grate 2 and then calcined in a rotor kiln 9 equipped with a kiln burner 10, a plurality of burners 31 are arranged in a range equal to 1/3-0.98 times the overall length L of the water separation chamber with the inlet 4b of the water separation chamber as a reference point. Gas fuel is blown from the plurality of burners 31 into the water separation chamber 4 and combusted by residual oxygen in preheat chamber exhaust gas A introduced into the water separation chamber 4 thus raising the temperature of atmosphere in the water separation chamber except the region close to the inlet thereof.COPYRIGHT: (C)2010,JPO&INPIT【課題】ペレット増産ないし高結晶水鉱石増配を確実に達成しうるペレット製造方法を提供する。【解決手段】鉄鉱石ペレットをトラベリング・グレート2で移動させつつ、乾燥室3、離水室4および予熱室5で順次加熱した後、キルンバーナ10を備えたロータリキルン9で焼成するグレートキルン方式の鉄鉱石ペレット製造方法において、離水室入口4bを基点として離水室全長Lの1/3~0.98倍の間に複数本のバーナ31を設置し、該複数本のバーナ31から離水室4へ気体燃料を吹き込み、該気体燃料を、離水室4へ導入される予熱室排ガスA中の残留酸素で燃焼させて、前記離水室内における、その入口近傍を除く領域の雰囲気温度を上昇させる。【選択図】図1
