There is also the 3 roller mill! On a 3 roller mill, a single roller sits below the top two rollers adding an extra step to remove the hard ends of under modified malts from the husk. All the grist falls through the third roller. Because of this 3 roller mills are more like 4 roller mills. Adding extra rollers does not mean more extract.
