A vertical mixer (50) for mixing bulk material is disclosed. The vertical mixer (50) includes an auger (20) having an auger post (200) and flighting including upper flighting and a lower flight. In one example, the auger comprises cutting knives (240) positioned on an outside edge of the flighting for cutting bulk material during rotation of the auger. The auger (20) also includes an angled knife (300) connected to an outside edge of the flighting and oriented so that a blade of the angled knife (300) is positioned at an angle suitable for allowing the angled knife to at least partially cut loosened bulk material that may be bridging in the mixing chamber (100) thereby at least partially preventing or reducing bridging in the mixing chamber and allowing the bulk material to fall towards the floor (120) of the mixing chamber and increasing the cutting action of the cutting knives. |
