Abstract
Abstract A mixer comprising a substantially trough shaped bin said bin being substantially rectangular when viewed in plan, the lower portion of each of the side walls of said bin slope inwardly to form a central longitudinal channel at the bottom of said bin, a 1st pair of horizontally mounted longitudinal augers situated in said trough and rotatably driven so as to feed from the front to the rear of the bin and also cause the feed to be fed upwardly and away from the centre of said trough, a 2nd pair of horizontally mounted longitudinal augers positioned wider apart and above 1st said pair and caused to rotate and feed in the same direction as 1st said augers.

Claim 1
Independent Claim
217 words
A material mixer comprising: an elongated substantially trough shaped bin having side and end walls, said side walls sloping downwardly and inwardly to form a central longitudinal channel at the bottom of said bin; a first pair of horizontally extending augers mounted rotatably for rotation in opposite directions within said bin adjacent the bottom thereof and having flights arranged to convey material from one end of said bin to the other end of said bin and upwardly within said bin; a second pair of horizontally extending augers mounted rotatably within said bin above said first pair of augers spaced apart further than said first pair of augers, the augers of said second pair being adapted for rotation respectively in the same direction as the respective underlying auger of said first pair and to convey material from said one end of the bin to said other end; a hammer mill mounted adjacent said one end of said bin in communication therewith; a recessed channel extending between said bin and hammer mill to provide said communication therebetween; said first pair of augers extending from said bin into said hammer mill for the conveyance of material from said hammer mill into said bin to the said other end thereof; and means for rotating said first and second pair of augers.
