弗斯特密斯(First Miss)金矿安装了一套监控系统,它是以Pavilion技术的过程检测中枢网络软件和液压系统的PI数据收集系统为基础的。第一个成功的控制回路是中和流程中石灰石添加速度的控制。由该流程控制而得以改进的是使每日能节约成本31000美元。尽管这只是该系统取得的初步成果,对调浆流程的监控还没取得成功,但模拟过程中取得的数据表明,对预调浆流程工艺过程的改进可获得每月54000美元的成本节约。
The First Miss Gold Mine installed a monitoring system based on Pavilion’s PI data collection system for central network software and hydraulic systems. The first successful control loop was limestone addition speed control in the neutralization process. Improved by this process control was a cost savings of $ 31,000 per day. Although this was only the first result of the system and monitoring of the slurrying process was not successful, the data obtained during the simulation showed that a cost savings of $ 54,000 per month was achieved for the improvement of the process of the pre-slurrying process.
