降低硬度在粗磨阶段起主导作用,宜用降低硬度型助磨剂;细磨时流变性占主导作用,宜用降低粘度型助磨剂。理想的助磨剂是二种类型兼而有之的药剂,在尚无该药剂的情况下,可以混合用药,达到助磨剂的最佳使用效果。研究证明,油酸和十二胺在稀矿浆中可改善磁铁矿和石英的磨矿效果,高浓度下二者都会恶化磨矿过程。因而对易磨的矿 Reduce the hardness in the coarse grinding stage play a leading role, it is appropriate to reduce the hardness type grinding aids; fine grinding rheological dominate role, it is appropriate to reduce the viscosity type grinding aids. The ideal grinding aid is a combination of two types of agents, in the absence of the agent, the drug can be mixed to achieve the best use of grinding aids. Studies have shown that oleic acid and dodecylamine improve the grinding effect of magnetite and quartz in dilute slurries, both of which deteriorate the grinding process at high concentrations. Thus easy to mill mine
