Overflow Rod Mill: Recommended for normal wet grinding in rod mills. The diameter of the discharge trunnion is larger than that of the feed trunnion giving an easy material flow through the mill. The discharge trunnion can be furnished with a trommel screen to remove rod fragments, wooden chips etc. from the mill discharge.
the mill table, due to mill and roller's relative movement, materials get into the grinding layer between the roller and the mill. In suspension between classifier and table, material drying transpires will takes place. The unstable grinding bed causes the VRM to vibrate. Water is directly sprayed into the bed to make dry mill feed, which is
