鲍店选煤厂煤泥减量生产实践

Practice of coal slime reduction in Baodian Coal Preparation Plant

煤泥作为煤炭洗选生产过程中的一种副产品,对选煤厂的洗水平衡和经济效益有着重要影响,因此如何有效减少入洗原煤中的煤泥含量、降低洗选过程尾煤泥的产率和产量已成为选煤厂技术升级的重要课题。鲍店选煤厂通过分析煤泥的来源、特性及其对洗选生产的影响,从源头管理、过程管控、末端回收三方面开展煤泥减量工作,最终实现了降低煤泥产率、减少煤泥产量、提高洗选效益的工作目标。

Coal slime,as a by-product in the process of coal washing,has an important impact on the balance of washing water and economic benefits of coal preparation plant.Therefore,how to effectively reduce the content of coal slime in the raw coal washing and reduce the yield and output of coal slime in the washing process has become an important topic for the technical upgrading of coal preparation plant.By analyzing the source and characteristics of coal slime and its influence on washing production,Baodian Coal preparation Plant carried out coal slime reduction work from three aspects:source management,process control and end recovery,and finally achieved the goal of reducing coal slime yield,reducing coal slime output and improving the level of washing innovation.
