Acoustic Monitoring of Mill Pulp Densities

In this paper, acoustic sensor has been utilised in a laboratory batch ball mill operation to investigate the effect of pulp density dynamics (50, 57, 61 and 67 wt. % solids). The results showed good acoustic response with changing mill pulp density. The mill product size distributions were statistically the same for the investigated pulp

Identifying grinding mill dynamics using acoustic

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

Controlling ball mill noise with acoustic blankets: A case

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

Optimization of mill performance by using

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

On-line sensors for measuring the total ball and charge

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 (1200-2800kg/hr) and ball loads (15-26%). The static mill filling was determined from physical measurements after crash stopping the mill.
