  • Deep convolutional neural network for mill feed size characterization 
    Olivier, Laurentz Eugene; Maritz, M.G. (Michael); Craig, Ian Keith (International Federation of Automatic Control, 2019)
    Knowing the characteristics of the feed ore size is an important consideration for operations and control of a run-of-mine ore milling circuit. Large feed ore variations are important to detect as they require intervention, ...
  • Estimating ore particle size distribution using a deep convolutional neural network 
    Olivier, Laurentz Eugene; Maritz, M.G. (Michael); Craig, Ian Keith (Elsevier, 2020)
    In this work the ore particle size distribution is estimated from an input image of the ore. The normalized weight of ore in each of 10 size classes is reported with good accuracy. A deep convolutional neural network, ...
  • Feed size distribution feedforward control for a grinding mill circuit 
    Maritz, M.G. (Michael); Le Roux, Johan Derik; Craig, Ian Keith (International Federation of Automatic Control, 2019)
    This paper proposes a method to measure and reject disturbances caused by changes in the ore distribution of the feed to a grinding mill circuit. A computer vision system is presented to measure the fraction of rocks in ...
