MODELING OF THE SECONDARY GRINDING SYSTEM AT SAMARCO MINERAÇÃO
Abstract
Overflow ball mills are pivotal in iron ore processing worldwide, despite their significant operational costs and energy demands.Since industrialscale testing is often time-consuming and expensive, this research employed laboratory-scale experiments using the Population Balance Model to optimize Samarco's regrinding circuit.By applying the MolyCop Tools software to data collected from the industrial site, the study characterized samples and conducted batch kinetic tests to define breakage and selection parameters.The final model demonstrated strong reliability, proving that laboratory data can accurately simulate and enhance industrial grinding performance.
