在机械加工工程以及选矿过程中，悬浮液通过设备、管道等的流动起着至关重要的作用。在矿山开采中，尾矿的运输在矿山的回填和问题废物（矿渣、灰分、浮选尾矿、含硫烟气洗涤过程中产生的石膏等）的处理中显得尤为重要，对环境保护具有重要意义。理论原理是我们在实验室通过流变学检查（粘度法）获得的，作为我们计算管道输送的基础，因为在水中输送粗颗粒和细颗粒混合物的可行性似乎几乎完全取决于细颗粒悬浮液的性质（B o . h . & Meier,1987）。在IRGO（采矿，岩土技术和环境研究所），我们开发了自己的管挤压流变仪，这使我们能够建立悬浮液的流变特性，在此基础上，我们可以确定用于工业采矿中浓缩悬浮液运输的管的尺寸。（E b E r 1 & E b E r 1,1995）。萨格勒布,1995年。
Introduction In the mechanical process engineering as well as in the mineral processing the flow of suspension through equipment, tubes etc. is playing an essential role. In mining the transport of tailings has become of special importance in connection with mine backfill and lately also with disposal of problematic waste (slag, ash, flotation tailings, gypsum from process of scrubbing sulfur-laden flue gasses etc.) wich has proved of great importance in environmental protection. The theoretical principles, wich are serving us as basis for our calculation of transport through the tubes, are gained in our laboratory through rheological examination (viscometry) since the feasibility of transporting a mixture of coarse and fine particles in water seems almost solely dependent on the properties of the suspension of fine particles only ( B o t h e & Meier ,1987) . At IRGO (Institute for Mining, Geotechnology and Environment) we have developed our own tubeor extrusion rheometer which is enabling us to establish the rheological properties of suspensions on the basis of which we can dimension the tubes for transportation of concentrated suspensions in the indrustrial mining.
