  • how to solve the noise of ball mill Machinery

    The solution about the noise of ball mill. 1.Acoustic enclosure (soundproof hood) Use the acoustic enclosure to cover the whole ball mill and then add a sound absorbing device in the hood to eliminate the reverberation noise. This method usually gains the noise reduction of 25-45db (A) but it does not effectively isolate the ball mill

  • Electronic Sound MonitorJayashree

    The sound emitted from the Ball Mill varies in intensity as the quantity and average size of the material in the mill changes. This sound is caused by the grinding ball hitting the mill lining and the material in the mill. A high noise level indicates an under-loaded mill and a low noise level indicates an overloaded mill. Both these conditions
