An Improved Control Strategy for Ball Mill Grinding Circuits

 · An improved control strategy is proposed to control ball mill grinding circuits for energy saving and pollution reduction. A two-layer optimization architecture combined by particle size optimization layer and energy optimization layer is developed, where the optimal particle size set-point is calculated first, followed by the energy optimization step.
