Get Price2020-6-23 Converting a mill from an overflow to a grate discharge arrangement leads to an increased power draw. This happens because the installation of the grate discharge arrangement enables the mill to run with a lower level of slurry due to it being no longer necessary for the slurry to build up inside the mill until it overflows from the mill discharge.

Get Price2003-7-1 Typically in wet overflow grinding mills the product is allowed to exit the mill by overflowing the discharge trunnion. The driving force for flow of slurry from the feed to discharge end of the mill is the flow gradient due to the discharge trunnion being larger than the feed trunnion. However, grate discharge mills have a more complex mechanism.
