球磨机料位检测仪的开发及其在优化运行控制上的应用

料位检测仪是利用球磨机运行时发出的振动信号，根据对各台不同工况下球磨机振动信号的分析，得出了表征球磨机变化情况的信号，采用该信号并融合磨煤机其他的运行信号，就能将球磨机控制在*佳运行工况。这种控制自1999年起已在多台中储式制粉系统上成功应用。运行表明，该技术能使电站制粉系统运行更**、更经济。

Abstract：Introduced a method to measure the loading of tube mill,which used the vibration signal of tube mill to represent the loading of tube mill and used the monitoring of the vibration level being character at different loading.A soft-sensing method based on fuzzy reasoning control is proposed;it is applied in optimal operation control of the tube mill. The operation result shows that it s quite suitable for the control of tube mill and a large amount of electric energy is save.
