An Analysis Of Mill Grinding Noise. Jan 01 the ball size ranges adopted were 127 635 mm 190 127 mm 254 190 mm and 254 mm the mill noise variaton with time was then investigated using a 99 kg charge of mixed balls and 500 g of 66 46 mm dolomite the mill noise level was monitored continuously for 32 min and the ore was sized at discrete time
Vertical grinding does not have the metal impact of the ball in the ball mill colliding with each other and hitting the liner, so the noise is 20 to 25 dB lower than ball mill. In addition, the vertical mill uses a fully enclosed system, the system works under negative pressure, no dust, and the environment is clean.
