  • How a Grate Discharge Ball Mill Works 911 Metallurgist

    Mar 17, 2017 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.

  • Choosing the Best Media Mill For Your Wet Grinding Appliion

    Jul 1, 2003 Hydraulic packing occurs when drag forces on the media due to product flow overcome the natural turbulence of the media, forcing the beads to statically pack around the mill's discharge screen. This phenomenon occurs more easily with lighter and smaller grinding media and also with higher product flow
