Portable feed grinder-mixer

The method of mixing ground feed within a bin having vertically extending upper sidewalls and having lower sidewalls sloping downwardly and inwardly therefrom, comprising:

• (a) moving and mixing portions of such ground feed within said bin and circulating the same in an annular circulation along a generally horizontal plane adjacent the lower portions of said bin sidewalls and along the periphery thereof while
• (b) simultaneously and separately moving and mixing portions of such ground feed from said horizontal annular circulation directly upwardly therefrom along a generally vertical plane from a position directly above the horizontal annular circulation of such first portions to the upper and outermore areas of the bin and thence downwardly along the sloping sidewalls of the bin into the generally horizontal annular circulation of such first portions.

A method of mixing ground feed within a bin comprising:

• (a) augering portions of such ground feed in a horizontal annular circulation along a generally horizontal plane adjacent the bottom of the bin, while
• (b) simultaneously and separately augering at least some of such portions of such feed upwardly and outwardly from a position directly above the annular circulation of such first portions of ground feed to the upper and outermore areas of the bin and in a generally vertical annular circulation along a vertical plane disposed directly above the horizontal annular circulation, and
• (c) augering such ground feed so as to cause said annular circulations to intersect and such feed to cross-mix between said paths.

A method of mixing ground feed within a bin comprising:

• (a) mechanically moving and mixing portions of such ground feed in an annular circulation along a generally horizontal plane adjacent the bottom of the bin, while
• (b) simultaneousely and separately mechanically moving and mixing portions of such moved ground feed from a position directly above said annular circulation directly upwardly and outwardly in an annular circulation along a vertical plane, said position being within the horizontal annular circulation of such first portions of such ground feed and such first portions moving to a second and relatively remote position within said horizontal annular circulation.
