After monitoring two 3-product heavy-medium cyclones with three accelerate sensors at the respective feed gate,the normal state and fault state signals were collected,two kinds of signals were processed by RMS(Root Mean Square) and kurtosis.The results show that the RMS change is more than 2 to 20 times between fault and normal signals.But the kurtosis change is inconspicuous.Based on the above results,a fault monitoring method was proposed with supervising the change of RMS.It can implement the real-time alarming and shorten the period of fault eliminated.
