Simulation of the Brenda Mines Ltd. Secondary Crushing Plant

The methodology employed to develop a digital simulation of the Brenda Mines Ltd., Peachland, B. C., secondary crushing plant is described. Methodology includes data acquisition, data adjustment, model building, and the construction of a simulator structure. The simulator was utilized to study the effects of secondary and tertiary crusher close side settings, secondary screen opening, plant feed rate, and percent + 1 in. in the feed on the following responses: percent - 1/2 in. in the final product, plant reduction ratio, circulating load ratio, and screen efficiency. Results are presented in graphical form.
