摘要： 以Z-164D为助磨剂，对广西田阳铝土矿进行了邦德球磨功指数试验和单轴抗压强度试验.结果表明:铝土矿经水和Z-164D溶液浸泡后，邦德球磨功指数分别下降了105%和379%，单轴抗压强度分别下降了2684%和4279%.红外光谱分析及X射线能谱微区元素分析表明，Z-164D只能在铝土矿表面发生物理和化学吸附，并不能够渗入铝土矿内部.建立了Z-164D溶液对铝土矿强度影响的作用机理模型，水分子与Z-164D相互促进，共同导致铝土矿缺陷程度增加、强度降低.

Abstract: Using Z164D as grinding aid， the Bond work index of ball mill experiments and the uniaxial compressive strength experiments of bauxite from Tianyang Guangxi were carried out separately. The results showed that compared with raw ore， the Bond work index of bauxite soaked with water and Z164D solution are decreased by 105% and 379%， and the uniaxial compressive strength are reduced by 2684% and 4279%， respectively. The physical and chemical adsorption between Z164D and bauxite surface are confirmed through the analysis of IR spectra and energy dispersive Xray spectroscopy， and Z164D cannot dip into bauxite inners. A function mechanism model of the effect of Z164D solution on bauxite strength is built， where water and Z164D promote each other to increase defects of bauxite and lower its strength.

Key words: bauxite, grinding aid, Bond work index of ball mill, uniaxial compressive strength, mechanism
