摘要
亭南选煤厂主洗系统进入706/707上仓带式输送机的混煤产品成分比较复杂,包括末精煤、粗煤泥、末原煤、中煤以及破碎块煤等,各产品分层明确,形成煤层,采制化验时代表性较差,不能指导生产。针对此问题,在706/707带式输送机上增设2道新研制的配煤均质器,介绍了配煤均质器的工作原理及结构特点,通过改造,实现产品均匀掺配,保证产品煤质量符合客户要求,减少了煤质扣款,提高了公司运营收入。
In view of the complex composition of the final coal products entering the 706/707 upper warehouse belt from the main washing system of the coal preparation plant of Tingnan Coal Preparation Plant, including the final clean coal, coarse slime, final raw coal, medium coal and broken lump coal, etc.The product stratification clearly forms coal seam, and the representativeness of the production and testing is poor, which cannot guide the production work well.In response to this problem, two coal blending homogenizers were added on the 706/707 belt to mix the coal flow to ensure the representativeness of the sampling.Through this transformation, considerable economic and social benefits will be created for the coal preparation plant.
