| Abstract: |
| The fill-level measuring and control system for ball mill is introduced，which is based on multi-sensor information fusion technology. The relationship between fill level and process parameter is researched based on the analysis of mechanical model. The selection of sensors for information fusion and the data acquisition are studied. The 3-layer shell vibration data acquisition equipment is developed，which is composed of data collector，data communicator and PC. The information fusion soft measuring of fill level is proposed based on LS-SVM （Least Square-Support Vector Machine） algorithm and the fuzzy control algorithm of ball mill load is proposed based on fill level measurement. Experimental results show that，the proposed system effectively measures the fill level of ball mill and optimizes the load control. |
