How to Improve Ball Mill Performance

Application of value engineering techniques to grinding process modelling led to the identification of two basic functions of the ball mill-classifier circuit. In terms of a specified circuit product size which is used to differentiate between “coarse” or oversize material and “fines” or undersize material, these basic functions are (a) breakage of the coarse material and (b) removal

One of the workhorses of the minerals industry is the autogenous grinding (AG) mill and its derivative the semi-autogenous (SAG) mill. These are relatively well understood, but not so Scrubbers.

Artificial intelligence applied to mill optimization

The APC models were tuned for a certain type of ores and were struggling to maintain performance in the light of changed ore conditions. The grinding mill was processing ores of variable size, shape, hardness, etc., and had to be controlled to mitigate the possibility of ore build-up inside the mill and subsequent overload or runaway conditions.

Operational parameters affecting the vertical roller mill

Apr 01, 2017 In this study, pilot scale tests were performed with a mobile vertical-roller-mill grinding plant to investigate the relationships between operational parameters. The identification and quantification of the grinding parameter relationships was carried out to implement these relationships into a computational vertical-roller-mill performance model.
