    Overload Detection in Semi-Autogenous Grinding: A

    Jan 01, 2015 The primary objective for a SAG mill is to maximize the throughput of fresh ore. Fresh feed ra e, however, is constrained by the total volume occupi by he charge inside the mill (Craig & Macleod, 1995). If the charge volum exceeds a certain threshold, the mill begins to overload and grinding efficiency decreases in a positive fee b ck mechanism
