智能浮选系统在西曲选煤厂的应用

Application of intelligent flotation system in Xiqu Coal Preparation Plant

西曲选煤厂为进一步提高浮精产率和尾矿灰分,降低浮选药耗和职工劳动强度,保证浮精产品质量,实施了智能浮选系统代替原有人工浮选加药技术改造,实现浮精灰分较改造前合格率提高10%,单位药耗降低3%以上,浮选精矿检测灰分与人工化验灰分误差不大于0.5%,浮选岗位由原有固定岗变成巡检岗。

In order to further improve flotation yield and tailings ash content, reduce flotation drug consumption and employee labor intensity, and ensure flotation product quality, Xiqu Coal Preparation Plant adopts intelligent flotation system to replace original artificial flotation dosing.Through the technical transformation, the qualified rate of float fine ash content increased by 10%,unit drug consumption decreased by more than 3%,the error of detected ash content of flotation concentrate and artificial test ash content was less than 0.5%,and the flotation post changed from the original fixed post to inspection post.
