研究了添加有机粘结剂Ｇ对制粒过程的影响．结果表明，添加有机粘结剂Ｇ使水在矿粉颗粒表面的润湿角降低，提高了矿粉的亲水性，强化了制粒过程；似粒子内部颗粒间受力分析表明，由于润湿角的降低使作用在润湿周边的界面张力以及毛细作用力增大，从而提高了似粒子的强度 The effect of adding organic binder G on the granulation process was studied. The results showed that the addition of organic binder G decreased the wetting angle of water on the surface of the ore particles, increased the hydrophilicity of the mineral particles and enhanced the granulation process. The mechanical analysis of intergranular particles showed that the wettability The reduction of the angle increases the interfacial tension acting on the wetting periphery and the capillary force, thereby increasing the particle-like strength
