  • Grate Discharge Advantage & Benefits Grinding

    In simple words, grate discharge mills give higher tonnage, but produce coarser grinding, that may cause problem in your Flotation recovery, Grate discharge will also reduce your EGL. The best In simple words, grate discharge mills give higher tonnage, but produce coarser grinding, that may cause problem in your Flotation recovery, Grate discharge will also reduce your EGL. The best option would be to place a retainer ring at discharge end to hold more charge & that will give you more throughputs without compromising grind size.
  • Rod Mill or Grate Discharge Ball Mill ? Grinding

    After the mill there would be a screen with 1mm opening, fines to spirals, coarse back to the mill. I used rod mills for such a coarse grind, but the handling of the rods is not as easy as if you use balls. So After the mill there would be a screen with 1mm opening, fines to spirals, coarse back to the mill. I used rod mills for such a coarse grind, but the handling of the rods is not as easy as if you use balls. So the question came up what a grate discharge ball mill would do here. I never used one.
  • How a Grate Discharge Ball Mill Works

    Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is “pumped” out and discharged. Discharge Grates The natural flexibility of rubber has allowed rubber manufacturers to
