<P>PROBLEM TO BE SOLVED: To provide a method for producing a sintering material, which improves the effect of adhesion of a solid fuel type powdery raw material to pseudoparticles of the sintering material, can increase the diameters of the pseudoparticles, and can realize still greater improvement in a production rate, a yield, a sintering time, and the diameters of pseudoparticles. <P>SOLUTION: The sintering material except the solid fuel type powdery raw material 4 is fed from the feed inlet of a drum mixer 5, and granulation moisture (granulation water a) added for granulation is added in such a weight ratio that the weight ratio to the total amount of water added is larger than the weight ratio of the added sintering material to the total amount of the sintering material to granulate the sintering material. The solid fuel type powdery raw material 4 is added to the zone set in the mid of the downstream side where the residence time taken until the sintering material reaches the exit of the drum mixer 5 is in the range of 10 to 120 sec. During the addition of the solid fuel type powdery raw material 4, the residual granulation moisture (granulation water b) is added to adhere and form the solid fuel type powdery raw material around the sintering material before it reaches the exit. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
