Resumo
The granulation process in the drum mixer of POSCO No 2 sintering plant was investigated to improve the productivity of sinter products. The retention time, sticking, and agglomeration of raw materials were estimated by laboratory scale tests. We found that the increase of retention time and the minimize of sticking of raw materials were effective factors for an optimum granulation process in the drum mixer. The lifter of triangle type and the blade with -15 degree of the drum mixer showed very low sticking. Air blowing of 100 m/s into the drum mixer increased the size of quasi-particles with the reduction of the sticking of raw materials. In addition, the moisture spray by a flat-type nozzle improved granulation properties of raw materials.
