摘要
为解决宁东洗煤厂羊场湾分厂介质回收效率低、分选自动控制系统不完善、浓缩机底流浓度较高、加药系统能力不足的问题,对介质回收及煤泥水系统进行分析,并采取了相应措施。通过工艺改造有效解决了该分厂存在的技术问题,降低了生产成本,创造了一定的经济效益和社会效益。
To solve the problems such as low in medium recovery rate, imperfection of separation automatic control, high concentration of of under flow of thickener and less ability of agent adding system existed in Yangehangwan branch of Ningdong coal preparation plant, analyzed the medium recovery system and coal slurry system, and taken corresponding measures, which effectively solved the problems above mentioned. The technology renovation effectively solved the problems in that branch, and lower the production cost, obtained certain economic and social benefits.
