Computer Design Of Grinding Circuit Flowsheets - Application To Cement And Ore Processing (Technical Paper)

A digital simulator of classification and grinding circuits is used to evaluate the performance of various flowsheets. For a given flows he et configuration, unit process dimensions, and operating conditions, the simulator calculates the steady-state values of the process variables and determines the conditions that meet the required operation criteria for tonnage and product quality. Calculation examples are proposed for the design of wet and dry grinding circuits. The performance of different configurations of cement clinker and sulfide ore grinding flowsheets is evaluated and discussed.
