  • Optimum SAG Mill Discharge Density Grinding

    Your ore, lifter design, pebble size, pebble port size, classification in your stockpile, etc will all have an effect, Higher densities result in longer retention, (more time to grind) prevent pooling (to a point) by allowing the pulp lifters to remove material pooling results in low energy impacts Low densities wash the fines and scats from the mill

  • Control SAG Mill sound detection Grinding

    The result of this control is a 25% increase in throughput, over the plant design, with a 10% reduction in energy consumption; the mill is more efficient The mill control manipulates the feed rate and mill speed depending on ore and liner conditions Liner
