Abstract: Ballmill noise became a matter of general concern with passage of the WalshHealy Act in 1969. This act is now a part of the broader safety act known as the Occupational Safety and Health Administration. Noise is one of the ``newest pollutants'''' in terms .
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.
Abstract: In the grinding process automatic control, detection and control of ball mill load is the important content of ball mill automatic control. Can detect the ball mill load accurately is a key to the success or failure of intelligent control of the whole ball. In the grinding sound signal measurements, the presence of the noise makes signal characteristics can not be extracted exactly ...

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
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 ...
commonly used control strategies are analyzed and discussed. Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics.

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.
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 .
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 ...
Dec 27, 2017· ball mill with demonstration of sound proofing. thick wood case with polystyrene layer and plywood lining.
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.
