An arcuate structure for bulk particulate solids which has inner and outer concentric containment walls. The space between the inner and outer walls is subdivided into a plurality of storage subspaces, and covered with a continuous roof. A radial stacker conveyor system receives particulate solids to be stored, and transfers these particulate solids into a selected storage space through access apertures disposed on a circular arc in the roof. To allow the radial stacker to access each roof aperture, it is rotatable about an axis concentric with the inner and outer walls, and the roof apertures are located on an arc concentric with the inner and outer walls. A separate radially located conveyor system is provided beneath the floor of each storage space, by means of which particulate solid stored in any chosen storage subspace can be retrieved through discharge gates located in the floor of each storage space above the conveyor, and transported to a delivery system adjacent to the radial stacker. The length of arc used for the structure is largely determined by the available space, and the chosen delivery system. Typically the arc length will be about 180.degree., and can be 360.degree.. Since the storage spaces and the conveyor systems can all be enclosed, localised pollution is minimised. Further, since all of the storage spaces are protected by a roof, the effects of weather on the stored particulate materials is substantially eliminated.
