  • Ball Mill Shell Vibration Signal Analysis Strategy Based

    Ball Mill Shell Vibration System Analysis . Normally, there are millions of balls inside the mill. Theoretically, these balls arrange in different layers. They impact the mill shell direct or indirect with different amplitudes and periods. Thus, the mill shell vibration signal caused by these forces must be consist of sub-signals with different timeAN EXPERIMENTAL ANALYSIS OF VIBRATION OF A BALL ,2018-1-4 · This paper deals with the experimental investigation of vibrations of a ball mill under variable load. The common causes of vibrations of the ball mill are described in short. The exciting frequencies at which the possible causes of vibration can be recognised are estimated for all principle parts of the ball mill. After that the measurement of accelerations of vibration at housings of bearings has been performed. Due to the production requirements the capacity of the ball mill is variable and therefore the torque on the ball mill drive is also variable. Measurement has been done for two different capacities. Vibration signatures have shown different vibration levels at different loads. It has been noticed that vibration amplitudes at the same frequencies decrease with increase of load of the mill. Keywords: ball mill, exciting frequencies, vibration

  • Experimental analysis of charge dynamics in tumbling

    Abstract Up until now, real time identification of the dynamics of the charge in a tumbling mill has not been accomplished. This paper examines the possibility of correlating the vibration signature of tumbling mills to characterize the motion of the charge and the state of grinding. Vibration signals were picked up using accelerometers mounted directly on the mill shaft of a 90-cm diameter mill.Mechanism characteristic analysis and soft measuring,Mechanism analysis for operational expert cognitive and ball mill numerical simulation are reviewed. The modeling process is summarized as a class of intelligent selective ensemble modeling problem. The emphasis is the applied soft measuring strategies for mill load parameter measurement.
