通辽选煤厂选煤工艺设计方案的确定

通过对内蒙古通辽选煤厂原设计方案的分析及调整,采用三产品重介质旋流器简化分选工艺,经生产实践的检验,达到了投资费用低、分选效果好、对原煤煤质适应性强的预期目标。选煤工艺方案的确定既要以煤质资料为基础依据,更要保证对原煤煤质变化有较广泛的适应性,尤其是入选外来原煤的选煤厂,同时还要结合厂型、设备性能、投资费用等综合因素,经过技术经济方案的综合比较来确定。 Three-product dence-medium cyclone was used to simplify coal preparation process by analyzing original design of Inner Mongolia Tongliao coal preparation plant.The actual production show that,after reformation,with lower investment cost,the effect of preparation is better and the process has strong adaptability to raw coal.The design of coal preparation not only should consider coal properties,also should tolerate wide range of raw coal properties,especially raw coal from other coal mines.The design also should combine plant types,equipments characteristics,investment cost and the like
