A cylindrical housing having diametrically opposed inlet and discharge openings contains a bucket wheel coaxially rotatable therein. The inlet opening is provided with an insert having an inclined upper surface and an edge for prestripping the grain material. The insert is further provided with a stripping edge forming an angle with the cylindrical generatrix formed by the surface edge of the blades of the rotating bucket wheel which angle is at least equal to the angle of friction between the bulk material and the material out of which the gate is formed. In addition, a canopy displacing wall is arranged in the inlet opening at the level of the end of the stripping edge to displace the material moving through the feed inlet. The wall has a width of such a dimension that the cavity formed beneath it is equal to at least the volume of the granulate material stripped from the stripping edge.

Bucket wheel gate for dispensing granulated bulk material

The gravity feed mixing of bulk materials is effected by removing partial quantities of the material at each of a plurality of vertically disposed levels, and passing the removed material through a series of funnels arranged vertically so that the material is admixed with the material passing from a higher level and fed to a lower level.

Process and gravity feed mixer for mixing bulk materials in a container

A gravity circulation mixer for bulk goods including a mixing container in which the bulk goods are divided into two quantity flows. After having recombined the two individual quantity flows of bulk goods in a mixing bowl, it is conveyed via a vertical ascending pipe and a gravity pipe back into the mixing container. The gravity pipe is arranged at an angle with respect to the ascending pipe and extends downwardly into the mixing container. The connection between the ascending pipe and the gravity pipe is constituted by a baffle portion so that the upwardly conveyed bulk goods are deflected at the baffle portion and caused to fall into the mixing container.
