摘　　要：采用低温氮气吸附等温线测定技术,系统分析了凹凸棒石原矿石经过粉碎、水相分选、挤压成片或粘结造粒之后表面积、孔结构、孔容和表面能量的变化规律,可为科学认识和选择初加工方式提供参考。The low-temperature isotherms of nitrogen are employed in the study on the influence of primary mechanical processeson the surface properties and pore structure of attapulgite, such as surface area, pore size distribution, pore volume and surface energy.The experimental data could be used for reference in the evaluation and selection of processing technics, including crushing, isolation,squeezing and graining.
