磨矿二段球磨浓度前馈串级复合控制系统的设计

Design of Feed Forward and Cascade Density Control System of Two Sectional Ball Mill in Ore Concentration

针对选矿过程两段闭路磨矿典型生产工艺,提出了二段球磨浓度的前馈串级复合控制方案,在溢流细度得以稳定控制的同时,保持二段球磨浓度相对稳定,较好地满足了生产要求。该控制系统已成功应用于宝钢集团梅山选矿厂的磨矿系统自动化改造中,效益显著。

In accordance with the typical production technique of two sectional closed loop ore grinding in ore concentration process, the combined control strategy of a feed forward and cascade density control for two sectional ball mill is stated. With this method, the slurry' s particle size and density are both well controlled to meet the production needs. This design has been successfully operated in Meishan Concentration Plant of Bao Steel.
