In this study, the effects of reduction ration on different mineral ores was investigated when using common size reduction equipment’s and also factors affecting the working efficiency during crushing. A laboratory model of a unified crushing operation was used as an estimate to account for performance at industrial level, how energy consumption in a treatment plant can be minimized. Prediction on breakage behavior and fracture energy was estimated for common crushers how chemical and physical properties of ore materials play a significant role in determining the crusher product specifications following PSD analysis. The rock ore studied in the research were modeled as granular particles subjected to crushing, grinding, and milling activities and their breakage mechanism was closely observed. Comparison between applied energy of the Jaws was studied and compared to estimated fracture energy for single particle breakage.
