ABSTRACT:
A mixing and conveying apparatus for dry materials, such as granules and powders, which mixes these materials uniformly in desired proportions and conveys them after mixing to desired elevated locations such as feed or storage containers, or the intakes of processing machines. The apparatus includes first and second auger conveyors which are positioned parallel to one another and extend generally in an upright direction. The first auger conveyor has an inlet at the lower end thereof and an outlet near the upper end thereof. The second auger conveyor has its outlet near the upper end thereof. A chamber connects the outlet of the first auger conveyor with the inlet of the second auger conveyor and this chamber extends on an incline between the conveyors. An opening is provided into the chamber for the introduction of additional materials which mix with the first material by gravity before the comingled materials reach the inlet of the second auger conveyor. The second auger conveyor has a greater transporting capacity than the first auger conveyor and thus draws material out of the mixer chamber faster than the first auger conveyor delivers material to the mixer chamber. In order to insure thorough mixing of the materials, the first material is discharged into the mixer chamber while moving in an upwardly direction while the additional materials are introduced into the mixer chamber while moving in an downwardly direction.
