Cement Mill Noise Level and Attenuation Report Page 3 2. Introduction This study was conducted to evaluate noise levels of both conventional ball mills and vertical roller mills for cement and/or slag grinding and to determine levels of attenuation of such noise in a space
regarding acceptable absolute levels of vibration. Discussions of some of these standards and their inadequacies are given in References 1, 2 and 3. The real intent of vibration monitoring, in our opinion, is to infer the absolute force levels or more basically, the stress levels, acting in the monitored machine. Based on the conclusions reached
rubber lined ball mill Manufacturer & stone lined ball mill … 1. Noise reduction: … The noise level emitted buy stone lined ball mill is usually 10-15dB lower than metal liner. 2. Corrosion resistance: …
Jan 25, 2013· The ball mill noise control is to control the noise output of the ball mill in the process of crushing materials by the engineering measures and is also to control the spread and receive of the noise, which is in order to reach the required acoustical environment. Ball mill is an efficient tool for grinding many materials into fine powder.
The ball mill can Reduce the ball mill noise below the allowable standard. (3) The ball mill uses a rubber liner instead of a manganese steel liner. The noise level can be reduced by 9dB (A), and the frequency spectrum characteristics of the ball mill are also changed from high frequency to low frequency. Ball mill design soundproof room.
Noise Monitoring for Optimal Mill Operation. Mining companies around the world continue to face the challenge of increasing productivity and reducing downtime. As part of its SAG mill control system, Manta Controls developed the Manta Mic: a robust and reliable acoustic analyser that prevents mill damage.
Dec 05, 2010· Assuming that the noise id due to the balls impacting on the drum of the mill, I would wrap the outside of the drum, and the ends with a dense mat of felt like material around 100mm thick, protect it with an outer layer of aluminum sheet.
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. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
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'.
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.
Oct 23, 2015· Low noise level. Well-proven mill components. A third of the grinding pressure of the roller press and moderate grinding pressures. Long life of wear segments. Drying and cooling ability. Compact and simple design. High grinding capacity. Cement quality meets prevailing standards. Same or better strengths than cement from ball mill.
The purpose of wrapping ball mills with thermal/acoustic blankets is twofold: (1) to maintain the desired temperature inside the mill and (2) to reduce the sound emanating from the mill. This field case study focuses solely on the latter, evaluating and documenting the sound level reduction attributed to the installation of the blankets and its potential to reduce the noise dose experienced by ...

Example Ball Mill GrindingExpert ™Solution The throughput and efficiency of a SAG mill depends on the volumetric load: An overloaded mill has reduced coarse ore breakage, as the cascading balls and rock cannot drop far enough, reducing kinetic energy for breakage. An underloaded mill will break coarse ore well, but at the expense of added
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.

Electroacoustic supervision of the filling level in ball grinding mills. Function : The electronic Ears senses the noise of the mill. The Ear consist of a very sensitive microphone installed at the mill inlet, at the grinding ball impact point, and as close as possible to the mill shell. The foam of the Electronic Ear must nearly touch the mill ...
