Abstract: This invention relates to a plant for the preparation of floated fodder, i.e. fodder in aqueous suspension made from humid grit or granulate and water with supplementary nutritional components and is based on a gastight high-rise silo comprising a central gravity shaft to which the grit is fed and from which the grit is extracted at the bottom via a conveyor facility. In accordance with the invention, a metering worm or screw opening onto a mixer is joined in gastight manner to the outlet of the bottom silo extractor, a second open mixer receiving supplementary nutritional components from containers which are not necessarily gastight, via individual metering worms or screws being situated in the water supply pipe or in the delivery pipe of the mixer.

Abstract: The pneumatic conveyor for grain consists of a horizontal conveying space, which accepts the falling grain at one end and whose discharge end terminates in an upward-narrowing vertical conveyor tube adjacent to the horizontal conveyor line, the grain being conveyed on a flow tray by a bypass flow or mechanically into the lower part of the vertical tube.

Abstract: The invention relates to an apparatus for granulating corn-cob mix and for conveying the granulate into a silo, transport truck or the like, including a mill comprising an integrated blower and a conveyor pipe joined tangentially to the blower. The mill is constituted by a beater mill that comprises a blower located behind a sieve within a circular casing and having a rotor arranged concentrically therein. A suction pipe is connected to the beater mill and comprises a secondary air opening adjustable in width, the suction pipe passing into a chamber supplied with the material which is to be milled from a reception container by means of a conveyor screw or other conveying means and the width of the suction pipe is greater by 35-70% than the width of the conveying pipe at the pressure-side of the blower. This enables the setting of the supply of material to be milled to the mill comprising a blower once, without having to undertake another governing operation.

Abstract: This invention relates to the draining of bulk materials which are not spontaneously flowable, from a high-rise silo in which the bulk material is fed from the top layer of the bulk material at any instant, into a central gravity shaft having a bottom extraction facility. To this end, the invention consists in a gravity shaft which is combined with the gastight high-rise silo and is rigid, stationary, tubular and closable at the bottom. The shaft is provided with perforations distributed along its height and circumference, of which at least one is situated at each vertical position of the prevailing level of bulk material. The bottom of the shaft can be sealed off with a slider or a plug of the material which is permitted to be built up to a predetermined height.

Abstract: A round silo for storage of different kinds of grain, especially damp grain, in layers one above the other, in a predetermined ratio, so as to facilitate a desired mixture of different grain kinds. The silo is of the type including a central bottom outlet opening. The central bottom outlet opening is in the shape of a conical deflector having a truncated conical surface, with the point thereof upwardly facing, and an outer peripheral edge disposed at a predetermined distance from the bottom of the silo. Furthermore, the silo is provided at its bottom end with an annular zone defined outwardly by the silo wall and inwardly by the outer peripheral edge of the conical deflector. A rotatable blade is mounted at the bottom of the silo beneath the conical deflector for rotation around the central axis of the silo for conveying grain toward the center of the silo and the conveyor means.
