Análise visando à substituição de um moinho autógeno por um moinho tradicional segundo o método de Bond

Abstract

Milling aims to reduce the size of particles in order to release the material of interest with the desired concentration for the following steps. Industrial grinding is mainly carried out by equipment called mills, with the ball mill, bar mill and autogenous mill being the three of the main known types. One of the main quantities used in mil sizing is the power spent in the process. In the present work, we studied the possibility of replacing an autogenous mil, in an iron ore processing plant, by a traditional mill, either balls or bars. The type that presents the best energy performance will be verified, keeping the same particle reduction and using the Bond method in the calculations.
