The present invention is a new method to efficiently reclaim cement from a horizontal warehouse. This new reclaiming method combines a mechanical cement reclaiming machine, together with a reduced amount of open air slides. Material is fluidized through a porous media with low pressure air. Material flow is achieved by sloping the Air slide conveyor to match the fluidized angle of repose of the powdered material. Further, the present invention introduces a conveying system, comprising a cascade of open and enclosed air slides and elevator machines, to convey the cement from the reclaiming area to a dispatch hopper. The introduction of these components, together with cement stacking and dispatch systems, is a Fully Automated Cement Horizontal Storage system and method.

A hopper bottom a grain bin above a foundation includes a conical wall tapering inwardly to a bottom discharge opening. An outer cylindrical wall is joined to the top peripheral edge of the conical wall. Upright support legs are connected to the outer wall for supporting the cylindrical grain bin walls thereabove. A bottom wall is connected radially between the outer wall and the conical wall so as to define a manifold passage bounded by the conical wall, the outer wall and the bottom wall which is generally annular in shape and which is located externally of the conical wall. Vent openings are formed in the conical wall to receive aeration air from a blower connected to the manifold passage. A cover member is supported above the vent openings in the conical wall in connection with the outer wall above the conical wall to prevent material entering the vent openings.
