磨矿分级自动控制系统在棒磨山铁矿的应用

Application of the Automatic Control System for Grinding-classification Operation in Bangmoshan Iron Mine

介绍了磨矿分级自动控制系统的原理及自控系统在棒磨山铁矿一段磨矿分级作业中的应用情况。试验和生产实践表明 ,自动控制与人工操作相比 ,一段磨机台时处理能力提高 5 .2 %、磨机利用系数提高 0 .0 6t/(m3·h) ,年创效益 46 .

The principles of the automatic control system for grinding classification operation and its application in the primary grinding classification operatoin of Bangmoshan Iron Mine are described.Tests and production practice have shown that automatic control can raise the unit hour capacity of the primary grinding mill by 5.2% and the mill utilization rate by 0.06 t/(m 3·h) when compared to manual operation,creating an annual return of 0.465 million yuan.
