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.
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 ...
Ball mills use of engineering noise control measures to control theball mill machine crushing noise generated at the output, control noise transmission andReceiving, in order to get people to the required acoustic environment, noise control is the ball mills. Ball mill machine in the crushed material can produce strong Vibration and noise ...
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
ball mill Articles – Page 1 – . months since the average units of the ball mill yield higher than that of multilevel with the . ball mill noise control is to control the noise .
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.
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.
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 ...
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
Cement Plant Noise Control and Soundproofing. There are several articles, white papers, and guidelines published concerning MSHA noise regulations for cement plants. Hygienists, safety personnel, miners, employees, and managers should become familiar with these guidelines as published by MSHA. ... Ball Mill Sound Blanket. eNoise Control can ...

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 ...
