The auger comprises flighting have an outside edge defining the periphery of the auger. A knife is provided, connected to the periphery of the flighting in a continuous or substantially continuous manner along at least a major portion of the periphery of the flighting of the auger. The continuous or substantially continuous knife may include knife sections placed adjacent and substantially longitudinally to one another thereby providing a continuous or substantially continuous knife. The auger having the continuous or nearly continuous knife along the periphery provides a substantially clean cut of fibrous bulk material and a reduction in crushing and/or tearing of the fibrous material relative to an auger with a non-continuous knife or an auger with a serrated knife. ## Claims ### Claim 1 An auger for a bulk feed mixer, the auger comprising: an auger post; flighting extending from the auger post and comprising an outer edge defining a periphery of the flighting, a bottom of the flighting ending in a leading edge spanning from the outer edge to the auger post; and a knife positioned on the periphery of the flighting, wherein the knife is a continuous knife, wherein the knife is comprised of a plurality of knife sections placed adjacent and substantially longitudinally to each other to form the continuous knife, and wherein a knife section of the plurality of knife sections overlaps an adjacent knife section of the plurality of knife sections and is connected to the flighting in an overlapping region. ### Claim 2 (depends on 1) The auger of claim 1, wherein the knife sections are connected to the flighting with a flush fastening connector. ### Claim 3 (depends on 1) The auger of claim 1, wherein the knife sections are connected to the flighting with a weld nut and the knife section comprises a recess for at least partially accommodating a flange on the weld nut so that, after connection, an external surface of the weld nut is flush or nearly flush with a surface of the knife. ### Claim 4 (depends on 1) The auger of claim 1, wherein the knife comprises a non-serrated sculpted blade. ### Claim 5 (depends on 1) The auger of claim 1, wherein the knife comprises a scalloped blade or a wavy double bevel blade. ### Claim 6 (depends on 1) The auger of claim 1, wherein an underside of the outer edge of the flighting is beveled. ### Claim 7 (depends on 1) The auger of claim 1, wherein the auger is a square auger. ### Claim 8 (depends on 1) The auger of claim 1, wherein the knife sections are substantially straight sections along a periphery of the outer edge of the flighting. ### Claim 9 (depends on 1) The auger of claim 1, wherein the auger is installed in a mini-mixer. ### Claim 10 (depends on 1) A bulk feed mixer comprising one or more augers as defined in claim 1. ### Claim 11 (depends on 10) The bulk feed mixer of claim 10, wherein the bulk feed mixer is a vertical mixer. ### Claim 12 (depends on 1) A bulk feed mini-mixer comprising one or more augers as defined in claim 1. ### Claim 13 (depends on 12) The bulk feed mini-mixer of claim 12, wherein the bulk feed mini-mixer is a vertical mixer. ### Claim 14 (depends on 1) The auger of claim 1, wherein the auger is installed in a vertical bulk feed mixer.
