ABSTRACT:
A bin adapted for storing and dispensing particulate materials is formed by joining two or more bin modules of similar shape. The linear dimensions of the modules increase in a geometric series, with the smallest module being at the bottom. The modules are designed to prevent arching of the particular material to assure mass flow. Three embodiments of bin modules are described. In the first and the third embodiments, each module consists of two sections, but in a second embodiment the module consists of four sections. A bin constructed of these modules requires appreciably less head room than does a conical bin.
