使用优质重介质 提高精煤回收率

Application of high quality dense-medium on clean coal recovery improvement

为了解决当前重介选煤厂重视介质价格、轻视介质质量的问题,从现场实践出发,对介质质量与精煤回收率的关系进行了探索,并对影响精煤回收率的诸多因素进行梳理,通过加强介质质量管理,指标考核制度,四级巡检制度,编码定量管理,设备台帐管理,协同奖惩制度等举措,提出以介质性价比作为判定介质消耗的主要依据,进而加强技术管理,对选煤厂降低成本增加效益有重要意义。

To push dense-medium coal preparation plant to pay more attention to medium quality not just attracted by low price, investigate the relationship between medium quality and clean coal recovery from the practice. Analyse the influencing factors of clean coal. Judge the medium consumption by strengthening medium quality management, assessment system, four-level censorship, equipment book account system, reward and punishment system. Meanwhile, strengthening the management of technology can help to reduce the cost and increase benefits.
