JUDGEMENT OF BALLMILL'S MAXIMAL COAL PULVERIZING CAPACITY BASED ON GRAY INCIDENCE ANALYSIS OF SHAFT VIBRATION |
| |
| Abstract: | Through processing of digital signals,the energy spectrum of bearing vibration has been obtained,and the gray incidence dynamic matrix being improved,and the energy spectrum of front and rear shafts being analysed by using the said matrix,and the prediction method of maximal peak value of the ball mill's coal pulverizing capacity being put forward.Practical application shows that the said method has better accuracy for judging the ball mill's capacity,and can be used for on-line control and operation optimization of ball mills. |
