  • Controlling ball mill noise with acoustic blankets A case

    The purpose of wrapping ball mills with thermal/acoustic blankets is twofold (1) to maintain the desired temperature inside the mill and (2) to reduce the sound emanating from the mill. This field case study focuses solely on the latter evaluating and documenting the sound level reduction attributed to the installation of the blankets and its potential to reduce the noise dose experienced by

The head of the micropone is 4-5 cm in the rear and is protected by a fine grid covered by a thin plastic film at the level of the foam coat. Therefore fitted in foam the microphone is insulated from the interfering noises existing in the plant.
