Jul 05, 2020 A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. ... High machine noise level especially if the hollow cylinder is made of metal, but much less if rubber is used. 3. Relatively long

BALL MILL DRIVES, LOADED, HFD LEVELS, SEPTEMBER 1A 1B • Above is a plot of the high frequency HFD vibration levels at both the 1A & 1B ball mills when loaded (acceleration energy band from 2 to 20 kHz). • Note how HFD levels at 1A ball mill coupling-end pillow block bearing (PIH PIA) are much higher than that at 1B ball mill

Pilgar Mill Noise Levels Ball Mill. Apr 20 the average noise exposure level based on different lines in the hot and cold steelrolling mills were 852 261 db a and 833 310 db a respectively p which were similar to the average personal noise exposure in both mills

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

noise emissions as follows: “7. (1) Noise emitted from any premises or public place when received at other premises must not cause or significantly contribute to, a level of noise which exceeds the assigned level in respect of noise received at premises of that

Dec 24, 2018 Hello,Hoping that I am posting in the most appropriate forum (if not let me know where to redirect my question):I'm considering a Mockmill standalone mill. The only worry I have at the moment is the noise level as I live in a small apartment building, and I would not want to be known as that guy...I originally thought the Mockmill 100 would be plenty, but given how noisy it could get in my

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight

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

Oct 08, 2019 Ball mill is mainly used for grinding materials in the industrial production process. Due to the large volume and heavy tonnage, the noise ( strong vibration and noise ) generated is usually above 95dB (A), which is serious affects the physical and mental health of workers

capabilities, a noise level below 80 dB is found at 100 meters from the source, a noise level below 70 dB is found at 250 meters from the source and noise levels below 60 dB can be experienced at distances of 750 meters and beyond from the source

Jan 01, 1985 Initially, a series of tests were run to investigate the noise produced by the mill as a function of ball size and mill feed. 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
