of a laboratory scale vertical stirred mill using a Bond ball mill. An energy-based population balance model was developed to analyze the response in product size resulting from changing operating conditions. The model prediction was compared with the results obtained in the laboratory vertical stirred mill.
This paper presents the data obtained from the industrial circuit sampling as well as tests on a laboratory scale used to estimate the energy consumption. These results are also compared with tests in laboratory and pilot scale carried out for sizing the regrind circuit. KEYWORDS: Regrind, Vertimill, Minas-Rio, Itabirite, Energy consumption.
