摘要
焦作煤业集团公司中马村选煤厂原采用两段水洗溜槽工艺分选+13mm的无烟块煤,因入料中还有相当数量的夹矸煤,选后块精煤产品无法满足市场需求。后对块煤洗选系统进行了技术改造,在保留原一段水洗溜槽分选工艺的基础上,增设了浅槽重介质精选工艺,收到了良好的效果。
Because of more quantity middle coal in the feed, the old two - part washing chute process for separationg ＋ 13mm anthracite lump coal could not satisfy the market demand. Holding the first part washing chute process, the dense medium separation process had been added through technological innovation and practice shows good effect.
