ABSTRACT:
In a chip bin or similar cylindrical upright vessel for storing particulate material the interior generally vertical wall of the vessel has a surface configuration which reduces compression of particulates within the vessel so as to substantially prevent pluggage or particulate bridging. Three or more right circular cone frustrums having a larger diameter at higher portions than at lower portions are provided along the interior generally vertical, either one immediately adjacent the other without significant spacing between them, or in a discontinuous manner being spaced from each other a significant distance. The frustrums insure that the vertical pressure level throughout the vessel is less than about 250 psf (e.g. less than about 200 psf). The vessel may be constructed of concrete using slip forms, with the concrete providing both the exterior and interior of the vessel, or a steel shell may comprise the exterior. The bottom of the vessel includes a hopper, or a vibrating discharge, and if the vessel is a chip bin steam is added at various points within the vessel.
