Described is a mixing bin for mixing bulk goods, particularly by pure gravity flow, comprising a mixing pipe disposed at a substantially central location in an outer container and provided with a plurality of intake ports disposed at different levels for withdrawing bulk goods at different levels from a bulk goods column enclosed by the outer container. All intake ports open into a common interior space of the mixing pipe. A respective deflector baffle projecting into the interior space so as to obturate a part of the cross-sectional area thereof is disposed above each intake port to be passed by the bulk goods flow in the interior space. For improving the result of the mixing operation in a structurally simple manner the invention proposes to vary the size of the part of the cross-sectional area obturated by the deflector baffles disposed at the different levels, the selected size of the obturated part of the cross-sectional area being determined by the amount of the bulk goods to be withdrawn through the associated intake port.
A mixing bin for mixing bulk goods by gravity flow, comprising an outer container having a bottom provided with an outlet and a mixing pipe disposed substantially centrally in said outer container, said mixing pipe being provided with a plurality of intake ports disposed at different levels above said bottom for withdrawing bulk goods at said different levels from a bulk goods column contained in said outer container, all of said intake ports opening into a common interior space of said mixing pipe, said interior space having a cross-sectional area at each of said intake ports to be passed by the bulk goods within said interior space, a deflector baffle being disposed above each of said intake ports, projecting into said interior space and obturating a part of said cross-sectional area of said interior space, the parts of said cross-sectional area of said interior space obturated by respective ones of said deflector baffles disposed at said different levels above said bottom being of different size, and the size of the obturated part of said cross-sectional area at each level above said bottom being selected such that a desired amount of bulk goods is withdrawn through the associated intake port.
