ROSA, Germano Mendes  and  LUZ, José Aurélio Medeiros da. Mix grinding simulation by artificial neural network. Rem: Rev. Esc. Minas [online]. 2012, vol.65, n.2, pp. 247-256. ISSN 0370-4467.  http://dx.doi.org/10.1590/S0370-44672012000200014.

This paper discusses the results of a mixed grinding simulator application based on an artificial neural network (multiple-layer perceptron using a back-propagation-like algorithm with moment). The data used came from a previous paper entitled "Selective grinding of dolomite and quartz mixes". The Shewhart control chart for individual values was used in order to verify the statistical stability of the simulation process results, which was useful for testing acceptance. The results have displayed good performance of this tool related to mix grinding simulation, a common issue in the mining and metallurgical sectors.

Keywords : Selective grinding; size distribution; artificial neural network; simulation; control chart.
