摘要(Abstract):

介绍了浮选柱的结构、特点及其工业应用的效果。分析了浮选柱利用微泡浮选、逆流浮选及旋流离心力场强化分选的机理。分析了入料、操作及环境因素对浮选柱分选系统的影响。工业应用表明,FCMC-3000型旋流微泡浮选柱能在保证精煤质量条件下,提高精煤回收率。
FCMC-3000 cyclonic micro-bubble flotation column is a new type and highly efficient equipment for fine coal separation.It can accomplish roughing cleaning and scavenging in one pass and has good selectivity.Its structure,characteristics and industrial application effect are presented.The mechanism of the Cyclonic micro-bubble flotation column is analyzed which includes its comprehensive utilization of micro-bubble flotation,counter-current flotation and in tensification of centrifugal field by cycloning.Influences of feed,operation and environment on separation efficiency was analyzed.Applied analysis on practice of FCMC-3000 cyclonic micro-bubble flotation column indicates,it not only ensured the grade of the fine coal,but also the recovery.As a result,good economical result was achivered.
