There are different paths for the comminution of certain size ore down to a target size, such as primary crushing-single stage SAG milling, primary crushing-SAG milling-pebble crushing-ball milling or 3-stage conventional crushing-rod milling-ball milling. Different comminution alternatives result in variate investment (CAPEX) and operating (OPEX) cost options. Other than qualitative decision, decision maker (design engineer) should decide based on economics (CAPEX and OPEX). The COM_TRD_Sim software has been developed for size reduction trade-off. The software accepts the user defined schedule data, processes several different experimental indices available in the literature. It compares the economics for exactly doing the same job (for example: crushing/grinding from 800 mm down to 50 micron for all alternatives). Alternatively, the software estimates CAPEX and OPEX for size reduction of different alternatives for different tasks (from 800 mm down to 50 micron for single stage SAG or from 600 mm down to 150 micron for 3 stage crushing + rod + ball milling). The software predictions have been verified against several industrial applications and the case studies given in the paper show the software capabilities for new design challenges. This volume explains the software capabilities, infrastructure and the models utilized in the calculation order, which are from the literature and in-house models of MPES Engineering. There are almost 40 mathematical models utilized in the software including MacPherson-WMAC, Starkey-WSDT, SMC and Bond experimental indices.
