If a mill has available power, conversion of the discharge arrangement from overflow to grate can be beneficial in allowing increased throughput or a finer product size. Conversely, if the mill does not have available power then it is still possible to install a grate discharge and to draw the same power by using a lower ball charge.
Diaphragms, mill shell linings and grinding Separation of the ball mill into two (or three) compartment using the, grinding balls are retained; Fixation on discharge mill head or on the mill shell possible, Greater lifting heights produce higher impact energy; Distribution of the ball load.
The overflow mills use much simpler trunnion bearings to support the mill, whereas grate-only discharge mill would require a tire gear around the shell which is expensive and involves complex manufacturing process as the grate has to withstand the pressure exerted by the steel ball charge and allow slurry to discharge effectively."

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 gratescreens are veins like a pump impeller. As the mill turnsrotates the slurry is pumped out and discharged. Discharge Grates The natural flexibility of rubber has allowed rubber …
