Abstract: A large volume silo has in the center of the base a conical dome which, together with the cylindrical outer silo wall, defines an annular base. Open air conveyor chutes pass from the base area through discharge openings to flow regulators in the inner area beneath the conical dome. Closed air conveyor chutes follow on from the flow regulators and lead to a common storage tank in the inner area beneath the conical dome. The open air conveyor chutes can be separated from the bulk material in the silo area by cover slides moveable from the inner area of the conical dome over the open air conveyor chute. This repairs to the conveyor chutes without interrupting silo operation. The cover slides are operated from the interior of the conical dome.

Abstract: A silo for mixing dried and powdery materials such as cement. A number of discharge apertures positioned at different places at the bottom of a mixing silo are connected by conduits to a common receptacle such as an homogenizing silo. A flow control gate is coupled to each discharge aperture to allow material flow to the receptacle to be controlled. Three modes of operation are disclosed: a single flow-mode wherein the flow control gates are opened sequentially one at a time, a dual-flow-same-rate mode wherein pairs of flow control gates are sequentially opened to the same extent, and a dual-flow-different-rate mode wherein pairs of flow control gates are sequentially opened to different extents. A level sensor in the homogenizing silo is connected to a level indicator circuit which emits level indicator signals indicating whether the material in the receptacle is rising or falling, thereby allowing automatic adjustment of the material flow rate into the receptacle up to a predetermined cut-off level.
