A versatile one-dimensional hopper (12) is described as well as structures that result when the one-dimensional hopper is integrated with a conical bin (14) and when the one-dimensional hopper is integrated with a V-blender (36, 38). In combining the one-dimensional hopper with other structures, the diameter d of the outlet is first specified, and then the slopes theta 1 of the load-bearing surfaces are chosen to achieve specified flow characteristics. The load-bearing surfaces (22, 24) are then extended obliquely upward until, at some height their maximum dimension measured horizontally equals a value D determined by the structure to which the one-dimensional hopper is to be attached. Where the surface of the bin or other structure is higher than this height, vertical surfaces (32, 34) that extend upwardly from the periphery of the one-dimensional hopper are provided for the purpose of connecting the one-dimensional hopper to the structure above it. |
