In rod mills, the charge is swollen by particles of feed which separate the rods. If the mill is shut down immediately after the feed is shut off, the charge level will be greater than if the mill had been "ground out" prior to shutdown. Because of this, rod mills are normally operated with a 32 to 40 percent charge by volume.
