摘要
系统梳理了晋城地区无烟煤洗选加工和产品结构现状,研究了当地无烟煤可选性的规律和特点,指出了目前广泛采用的"块煤重介浅槽+旋流器"分选工艺的局限性和大多数工艺设计人员普遍抱有的当地块末煤应当分别洗选的认识误区,提出了无压三产品旋流器用于晋城地区无烟煤分选的可行性,并介绍了具体的工程实践案例。
The present situation of anthracite preparation and the product structure in Jincheng area is introduced,the coal washablity characteristics and its regularity are analyzed,the limitation current"shallow-bath heavy medium separator+heavy medium cyclone"process of local coal preparation is noted,and a broadly taking narrow idea of local coal preparation that coarse coal and fine coal should be prepared separately,and the feasibility of using non-pressure three product cyclone to prepare Jincheng anthracite,and an engineering example is given.
