摘　　要：新田选煤厂原煤8 mm分级,块煤采用浅槽分选机分选,其入料前要求高的筛分效率设备进行分级。分析了新田原煤的特性和相关筛分设备,根据弛张筛对黏湿物料高效筛分的优势,形成了弛张筛分级+浅槽分选工艺,优化了工艺布置,同时也延伸了浅槽分选机的有效分选下限。Raw coal is graded by 8mm in Xintian coal preparation plant,lump is sorted by shallow groove sorter,and it needs to be graded by high efficiency screen before it enters.Analyzed the raw coal properties and related screening equipment,according to the relaxation sieve efficiently screening the sticky and wet material,the process of relaxation screen grading+shallow groove sorting is formed.The process layout is optimized,and the effective sorting lower limit of shallow groove is extended.
