Inferential measurement of sag mill parameters IV / T. A. Apelt in Minerals engineering, Vol. 22 N° 12 (Octobre 2009) 

Public ISBD [article]  in Minerals engineering > Vol. 22 N° 12 (Octobre 2009) . - pp. 1032–1044 Titre : Inferential measurement of sag mill parameters IV : Inferential model validation Type de document : texte imprimé Auteurs : T. A. Apelt, Auteur ; N.F. Thornhill, Auteur Année de publication : 2009 Article en page(s) : pp. 1032–1044 Note générale : Génie Minier Langues : Anglais (eng) Mots-clés : SAG  milling  Autogenous  grinding  Modelling  Simulation  Process  control Résumé : This paper discusses a case study application of inferential measurement models for semiautogenous grinding (SAG) mills and is the fourth paper in a series of five papers on inferential measurement of SAG mill parameters. The development of the inferential measurement models of SAG mill discharge and feed streams and mill rock and ball charge levels, detailed earlier in the series, is summarised here. The models are then tested on plant data for validation and analysis. Model characteristics are explored to highlight model sensitivity and relative uncertainty. The results are encouraging while limitations are noted and potential avenues for further research are discussed.

Inferential measurement of SAG mill parameters V / T. A. Apelt in Minerals engineering, Vol. 22 N° 12 (Octobre 2009) 

Public ISBD [article]  in Minerals engineering > Vol. 22 N° 12 (Octobre 2009) . - pp. 1045–1052 Titre : Inferential measurement of SAG mill parameters V : MPC simulation Type de document : texte imprimé Auteurs : T. A. Apelt, Auteur ; N.F. Thornhill, Auteur Année de publication : 2009 Article en page(s) : pp. 1045–1052 Note générale : Génie Minier Langues : Anglais (eng) Mots-clés : SAG  milling  Autogenous  grinding  Modelling  Simulation  Process  control Résumé : This paper discusses a case study application of inferential measurement models for semiautogenous grinding (SAG) mills and is the last in a five-part series on Inferential Measurement of SAG Mill Parameters. Inferential measurements of SAG mill discharge and feed streams and mill rock and ball charge levels, detailed earlier in the series, are utilised in a simulation environment. A multi-variable, model predictive (MPC) controller simulation is developed from plant data and utilised to investigate the potential of utilising the inferential models in a mill charge control strategy. An operating curve is generated and discussed in terms of possible utilisation in conjunction with an MPC controller. The results are encouraging and potential avenues for further research are discussed.
