无压给料三产品重介质旋流器选煤工艺的优化设计与应用

Non-pressure feed three-product dense medium cyclone coal preparation process optimization design and application

利用当地煤种,采用单台三产品重介质旋流器技术,以单一低密度悬浮液系统一次性分选出精煤、中煤和矸石3种产品。入选原煤采用不分级、不脱泥入选方式,50~0 mm级全部进入重介质旋流器分选的优化工艺设计,并分析了生产工艺效果。

By using local coal,using a single three-product heavy medium cyclone technology,as a single low density slurry system one-time separation plant,China coal and waste rock 3 kinds of products. Selected raw coal using classification,dense selected way,50 ~ 0 mm level all into the optimization of heavy medium cyclone separation technology design,analyzes the effect of production process.
