As a process design engineer, you have been requested to give your professional advice on this brownfield redesign project. An ore is ground from a crushed product such that 80% passes a 500-micron sieve down to a size in which 80% passes an 88-micron sieve. A 5hp motor is sufficient for the required throughput and for grinding. If the requirements are changed such that grinding is now to be done to 80% passing a 125-micron sieve, but the throughput is to be increased by 50%, is the existing motor sufficient to operate the mill? Assume Bonds equation applies.
