The sinter pellet binder has very strong hydration, when it meets water, it disperses quickly into monomer and fills in the gap of the ore powder. 

At the same time, the adsorption water layer of the binder can make the green ball slide each other when it is impacted, so that the plastic deformation will not be broken and the drop strength of the green ball will be increased. The sinter pellet binder has strong affinity to the ore powder, improves the hydrophilicity of the mixture, promotes the rapid formation of the cue ball, shortens the pelletizing time, and increases the yield of the Green Ball, at the same time, the binder is easy to decompose and volatilize when the green ball is dried to about 600 °c, thus ensuring that the strength and the violent temperature of the green ball can be increased, and at the same time, the drying speed of the green ball can be increased, the drying time can be shortened and the production of the green ball can be increased, it is beneficial to improve the consolidation strength of the finished ball.
