Noise at Work: How Loud is Too Loud? Excessive noise at work can be irritating, distracting and potentially harmful to workers' physical and mental health. The problem is, many employers struggle to determine exactly what is an acceptable level of noise at work, perhaps unsurprising given the subjectivity of terms like 'excessive' and 'acceptable'.

Acceptable Noise Levels Of Ball Mill

Jan 01, 1985· The available energy of a mill for grinding is governed largely by the mill speed, ball charge and ball size. Again these parameters are reflected to some extent by noise levels and it is suggested that the reduction from mill/ball-only noise levels caused by the introduction of ore could be an indicator of coarse breakage and type of breakage.
