摘要：AbstractThis paper reviews high pressure grinding rolls crusher mass flow rate models, and proposes a new approach based on the continuity principle. A two-parameter function models the working gap. A second equation estimates the mass flow rate from the working gap, also with two parameters. The inputs comprise the specific force, the roll speed, and the ore density. Ten published data sets allowed validating the postulated equations. The fourth parameter was not significant in nine of them, although this unexpected conclusion may result from the small data set sizes. Sequential and global calibration workflows were compared. They both led to the same parameter distributions with similar computational duration.
