摘要
随着我国原煤入选量的大幅提高和基础研究条件的改善,选煤过程基础理论研究取得了长足进步,选煤技术和装备也得到快速发展。统计数据表明:浮选过程强化研究是当前选煤基础理论研究的热点方向;煤加工相关企业关注的技术热点按关注度由多到少,依次为选煤过程自动化、重介选、工艺设计与改造、选煤装备、浮选等。从选煤作业的目的来看,选煤生产对技术的现实需求和未来发展方向主要集中在特定产品的生产、降低动力煤加工成本和智能化三个方面。
With substantial increase of the volume of raw coal treated and noticeable improvement of conditions in basic research, China＇s coal preparation technology and equipment have seen rapid development, with the research in the basic theory of coal preparation process also making considerable progress. Intensification of flotation process is currently the focus point and the orientation of the study in this regard. For the coal-related enterprises, the technological points of interest are automation of coal washing processes, heavy-medium separation, technological process design and renovation, washing equipment, flotation circuit, etc. , in order of the degree of their concern. Viewed from the perspective of the purpose of coal washing operations, the realistic requirements and developing orientation of coal preparation technology are centered on 3 aspects, namely, production of specific products, reduction of power coal cleaning cost and realization of intelligent operation.
