The influence of the anionic polymer dispersing agent (APD) on the granulation of raw materials was investigated to improve the sintering productivity. This APD has the characteristic that helps the dispersion of fine particles into water and disperses the fine particles that are cohesive. Fundamental examinations showed that the APD increased the adhesion strength of pseudo-particles and increased the pellet strength after drying. Granulation examinations with raw materials showed the good relationship between dispersed ratio and GI-0.5, and the considerable improvement of the granulation was recognized clearly. It was also confirmed that this APD had increased the sintering productivity more greatly than the burnt lime depending on the pot test results.
