管道长距离输送浆体在技术、经济、经营管理上有明显的优点。国外已广泛应用。国内虽做了大量的试验研究工作,但精矿浆体的长距离压力输送管道尚未付诸现实。文章对管道输送的优缺点、应用情况、经济比较、主要流程及设计方面的问题作了简要介绍。 Long-distance pipeline transport slurry in technology, economy, management has obvious advantages. Abroad has been widely used. Although a large amount of experimental research has been done in China, long-distance pressure delivery pipelines for concentrate slurry have not yet been put into practice. The article gives a brief introduction of the advantages and disadvantages of pipeline transportation, application, economic comparison, main process and design problems.
