ball mill, cement mill, energy-saving ball mill, batch mill Ball mill s noise is caused by the above problems, and we have given clear solution. If your ball mill appears noise problem, you may solve it as the above methods.
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.
However, treating the remaining two mills still proved to be very effective, further reducing ball mill noise in the near field by as much as 10.0 dBA and producing far field noise reductions of

Ball mill sound sensor is an intelligent grinding sound measuring instrument that can directly and effectively measure the load of the ball mill by receiving and analyzing sound level.
The only one varying condition is the amount of slurry in the interstices between balls. The rms sound level is inversely proportional to the amount of damping exerted by the slurry. High level, low noise. Low level, high noise. In a SAG mill, most of these conditions are not valid.
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 is hollow grinding sound (low volume low grinding frequency), whereas for low material bed (min. filling level), there is high pitched sound (high volume high grinding ...

Jan 01, 1985 The ball size ranges adopted were -12.7 6.35 mm, -19.0 12.7 mm, -25.4 19.0 mm, and 25.4 mm. The mill noise variaton with time was then investigated using a 9.9 kg charge of mixed balls and 500 g of -6.6 4.6 mm dolomite. The mill noise level was monitored continuously for 32 min and the ore was sized at discrete time intervals.
Abstract. The noise generated by a ball mill during a batch grinding operation is investigated and the results show that, for a given ore, the noise levels may vary with time of grind, ore charge weight and mill speed. The role of the ore in absorbing noise energy is suggested as a possible control variable for the grinding process and as an indicator of product size distribution.
The noise of ball mill is also a difficult problem. Ball mill as one popular grinding equipment commonly used in chemical industry, metallurgy, mining and other industries, in the process of production, its minimum noise is 95 dB (A), up to 120 dB (A), which is one of the strongest noise in industrial production and it must be controlled.
