  • How a Grate Discharge Ball Mill Works

    1/5/2018· Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the seen in a grate when a mill is shut down are particles either in the process of being discharged or returning to the mill. A grate discharge mill that is “ground-out” would show the desired near zero blinding. The slots in the early grates

  • Overflow Versus Grate Discharge Ball Mills: An

    It has been widely accepted to go for grate discharge ball milling when a coarse product is preferred or to avoid production of extreme fines, but overflow discharge mills are preferred for their simplicity of design and production of finer product. In grate discharge mills the product is discharged primarily due to hydraulic gradient from the feed end to discharge end. Hence there is a

    The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal. In addition, operating mills at
