    Depending on the height of the material bed, the grinding media inside the Ball Mill causes a characteristic noise. In case of high material bed (max. filling level), there ishollow grinding sound (low volume & low grinding frequency), where as forlow material bed (min. filling level), there ishigh pitched sound (high volume & high grinding frequency)
