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 Control philosophy controlled to a mill load setpoint by automatically adjusting the ore feed rate, and the acoustic control controlled the mill speed. This is all a commissioning exercise and one of the things we wanted to do was incorporate an additional loop whereby mill speed is automatically adjusted to control mill weight/load.
The rollers may be smooth or corrugated to reduce slippage. The mill may consist of several rollers with gradually decreasing clearance between the rollers (Figure ). Roller mills are extensively used in the grain milling industry. Mills equipped with corrugated rollers are used in the initial stages of wheat milling.

how to reduce or control the ball mill,At present there are three ways for the noise control of the ball mill in the market 1 from the source of Governance the ball mill does not sound or sound is very small which will affect the grinding mechanism of the ball mill or grinding effect the current difficult to achieve
A Study in BallMill Noise Control 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 of the definition set forth in the Walsh ...
how to solve the noise of ball mill Machinery. 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.
Reasonable selection of steel ball and liner is an important way to reduce the wear of liner. Therefore, it is necessary to fundamentally reduce the loss of liner during the operation of ball mill by starting with the size and quantity of rigid ball and the hardness ratio between ball mill liner and steel ball.
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.

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.
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 ...
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.
