Analysis And Evaluating Of Noise Control In Cement Ball Mill And Its Control Measures 1Selva Kumar A and 2Abdul Zubair H 1PG Scholar, Industrial Safety Engineering, Knowledge Institute of Technology, Salem 2Associate Professor, Department of Mechanical Engineering, Knowledge .
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.

This new type of noise control soft acoustic curtain is gradually replacing the traditional rigid sound insulation structure. Machinery offers 3 ball mill noise reduction methods for your choice. Machinery specializes in the production of ball mill, rod mill, sand maker, crusher and other mining machines.
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.
On the whole, there are two ways to reduce the noise of the ball mill: first, the sound transmission path; second, the source of the noise. Reduce noise, create a better working environment, make the production of equipment more continuous and efficient, and bring greater profits to production.

This Appendix to the Noise Topic Inspection Pack provides information on established noise control methods for a range of highrisk activities, organised according to industry/sector. Inspectors should refer to the main Noise Topic Inspection Pack for guidance on the
Grinding Classification Circuits. ... Where I work now, Minera San Cristobal in Bolivia, we use sound control on both the SAG and Ball Mills. The result of this control is a 25% increase in throughput, over the plant design, with a 10% reduction in energy consumption; the mill is more efficient. ...
the mill decreases, the mill noise intensity grows inversely, as shown in Figure 7. This effect is the basis of the ''electric ear'' patented by Hardinge to control the mineral feed to ball mills. When the falling stream hits the liners in free fall, high energy impacts appear superimposed over the common mill background noise, as shown in ...
Flexoply isolation pads shall be resistant to water, brine, fungus and bacterial growth and shall produce only slight swelling in SAE 30 oil. Flexoply pads shall be Model NDF, by Kinetics Noise Control, Inc.
Electronic Ear is useful for Control Regulation of Ball Mills, using the grinding frequency signal for optimizing the Mill Output. It consists of an acoustic signal receiver (Microphone Unit / Sound Sensor) and specially constructed indicating interpreting electronic circuit (Control Unit).
5 practical ways to reduce ball mill noisecement n. On the whole, there are two ways to reduce noise in ball mill: one is to control the propagation of sound; the other is to start from the source of noise The noise in the equipment operation is reduced, which creates a better working environment for the users, which can make the production of the equipment more continuous and efficient, and ...
The main noise sources are expected to be from mine plant and equipment (excavators, haul trucks, dozers, graders etc.), the processing plant (crushers, ball mills and conveyors and drives etc.) and the power station (gas engines etc.). The nearest nonmining sensitive receptor to the mine site is Anningie Station homestead
How to control the noise generating of ball mill is a problem troubling many customers. In order to reduce noise and create a comfortable working environment, Machinery gives some basic suggestions to control noise.
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.
