| contents | Continuous grinding mill simulation using Austin's model André Carlos Silva José Aurélio Medeiros da Luz Ingeniería Grinding Simulation Comminution Comminution is a frequently-required step in mineral processing and is responsible for almost 90% of all energy consumption in a mineral processing plant. Tumbling mill design has been studied since the middle of the XIX century. There are many comminution models in the literature, with preponderance, however, of Austin’s model (2002) for mineral impact breakage. In this paper, Austin’s model was applied to tubular tumbling mills. Once Austin's model was proposed for batch processing of narrowly-distributed fraction sizes, an artifice has allowed it to be used in continuous grinding mill processes with widely-distributed fraction sizes. Interesting results were obtained with errors less than 0.005 for mills with sharp residence time distributions. 2012 artículo científico 1678-5428 https://www.redalyc.org/articulo.oa?id=81024949003 en http://www.redalyc.org/revista.oa?id=810 Exacta application/pdf Universidade Nove de Julho Exacta (Brasil) Num.3 Vol.10 |
