2003-7-1 · 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.
