  • Mill power draw models

    Mill Power Draw Models The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption modelsThis refers to highaspect AG/SAG mills Ball Charge Motion inside a SAG Mill With a higher density mill charge SAG mills have a higher installed power density for a given plant footprint relative to AC mills With the combination of finer grind and a lower installed powerSAG Mill Grinding Circuit Design 911metallurgistSAG mill drives (as GMDs) by some operators and principal motor designers/manufacturers until the reasons for known problems in design or manufacturing were better understood and resolved Accordingly, the latest 40 ft dia SAG mill is rated at 29 MW and 78% CS, with a 42 ft dia mill built but not yet operational The more recent optionMill drives: the desire for increased power and the
