This paper presents an implementation scheme to use acoustic signal as the control signal to regulate the operation of a grinding mill. ... fed into the ball mill. The acoustic sensors have been ...
Opportunities for improved mill control based on the data from the online monitor are also discussed, as well as the implications in terms of mill processing and maintenance performance. Recently a CSIRO monitor was also installed on a ROM ball mill and analysis of the vibration sensor data from this installation is currently underway.
Jun 30, 2020· It was indicated that level of the acoustic noise generated during mill operation is more associated with steel ball filling rate rather than the mill speed. Beamforming results suggested that grinding dynamics and mill charge shape can be reconstructed from acoustic noise measured at .
Grinding Mill Control Grinding Classification Circuits . · The required acoustic level is entered by the control room operator as a set point into the acoustic controller. The collected reject media these days should remain round and be reloaded into the ball mill as fully competent steel. There should be no media waste at all.
leading MillScanner™ acoustic Smart Sensor with our highly intelligent KSX Expert System software to significantly improve SAG/ball mill performance. MillScanner™ with AID™ (Accurate Impact Detection) is a cutting edge Smart Sensor that rotates with the shell of the mill to display a radial trend of
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 ...
Introduction. The ball mill is indispensable grinding equipment in the ore beneficiation to control the ball mill noise? Ball mill is mainly used for grinding materials in the industrial production process. Due to the large volume and heavy tonnage, the noise ( strong vibration and noise ) generated is usually above 95dB(A), which is serious affects the physical and mental health ...
The mill load (ML) of a wet ballmill is generally determined by using the lowsensitivity shaft vibration signal, acoustical signal from mill shell and mill power during the grinding process.

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).
As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
Having used weight control and power draw to control Mill operations, using Mill Sound to run a mill was a new one for me. I found it unusual and not that anyone else used that style of operation control to run their mill and did you find it more effective than the more traditional way
Mar 14, 2014· Re: Coal Mill Level Monitoring Sytem for a Roller Mill 03/14/2014 10:46 AM I worked on a Milltronics ball mill control system years ago and for what I recall sound pressure was only one process variable used to measure mill load.
The characterized PA flow is then construed as the feeder speed demand. The ballandtube mill control system, on the other hand, uses feeder speed control for maintaining mill level control only and so the fuel flow control is achieved through control of the feederwise PA flow to mill itself.
Through continuous improvement and the use of advanced technologies like SmartEar™, Pueblo Viejo are improving the control and operation of their SAG mill, resulting in reduced liner wear, more Title: 12th Mill Operators'' Conference 2014 Semiautogenous grinding (SAG) mill co
Acoustic vibration signal analysis and coal bunker level recognition system in ball mill is used as a tool of acoustic vibration signal analysis system to extract characteristic variable to control the coal bunker level. With this system, the ball mill can operate in a safely condition, and work efficiency can be improved. In this paper, the development of acoustic vibration signal analysis ...
The mill was configured to operate as a RoM ball mill. The experiments were conducted at varying mill speeds (75%85% critical speed), feed rate (kg/hr) and ball loads (1526%). The static mill filling was determined from physical measurements after crash stopping the mill.
Mar 09, 2018· "Electronic ear" is not "electronic ear"! It is time to make clear that there are fundamental differences between electronic filllevel measurement systems for ball or tube mills.
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 ...
Smart Fill Level Control. Dec 04 2007 smart fill interferencefree electronic ear for measurement of level and temperature in ball mills even today when it comes to comminution of large masses ball mills are the work horses in the mineral industries in the past the filling level of ball mills was to be determined by the use of specialized microphone schemes electronic ears which however showed ...
Keep your ball and pulp levels always under control! The Sensomag® provides at all time, accurate inmill ball level, pulp location and pulp density indications. This allows ball mill operators to finely follow their mill operation and seek for optimal working conditions and directly leads to operating cost reduction.
The KnowledgeScape adaptive control solutions work together to see, listen, and think about the best way to increase tonnage and optimize SAG and ball mills at all times and for all conditions. Our expert control ball mill strategies automatically adjust sump water and mill water addition, mill speed where available and can open and close ...
The system is based on acoustic sensors and proprietary process control software to predict and adjust the SAG mill operation according to impacts on the mill and other main process variables. King Becerra, FL Global Product Line Manager – Process Optimisation told IM : "There are eight audio sensors on a bidirectional mill, four on ...
