付村选煤厂浮选工艺系统关键环节精益升级

Lean upgrading of key links of flotation process system in Fucun Coal Preparation Plant

针对选煤厂浮选系统存在的产品质量不稳定、工艺设备运行效果差、浮选尾矿系统跑粗、人工操作随意性强导致生产系统稳定性差、浮选药耗高等问题,通过对精煤浮选质量关键环节的把控以及浮选药剂配方和加药工艺系统的精益升级,并采取规范员工操作行为、控制浮选入料粒度管理、安装浮选精煤消泡器、升级药剂配方及加药工艺等方法,达到降低浮选药耗、稳定产品质量、提高浮选精煤抽出率的目的,实现了浮选系统高效稳定运行和企业提质增效。

In view of the problems of unstable product quality,poor operation effect of process equipment,rough running of flotation tailings system,poor stability of production system caused by strong randomness of manual operation,and high flotation drug consumption in the flotation system of coal preparation plant,the lean upgrading of the key links of cleaned coal flotation quality control and flotation reagent formula and dosing process system,standardize the operation behavior of employees,control the flotation feed particle size management,install float defoamer,upgrade reagent formula and dosing process,etc.,to reduce the flotation drug consumption,stabilize the product quality,improve the float extraction rate,realize the efficient and stable operation of the flotation system,and improve the quality and efficiency of the enterprise.
