Abstract: An instrument for measuring certain physical properties of a sample of particulate material so that the flow characteristics of the material can be determined includes an improved compaction assembly having an upper piston (30) that is surrounded by a retractable sleeve (22) and further includes an improved test cell (40) having cylindrical walls (54), having a failure outlet smaller than the diameter of the failure piston (30), and having a false bottom (58) that can easily be removed from beneath a sample of compacted material to permit the failure portion of the test to be carried out. The tester can be used for determining the confined yield strength of the material, its bulk density, and its permeability.

Abstract: 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.

Abstract: The invention relates to controlling the discharge rate of solid particulate material from a hopper. The problem associated with discharging material from hoppers is the material may arch or bridge within the hopper resulting in an unpredictable flow. The present invention provides a discharge rate of material from hopper (8) increased beyond the rate attainable by gravity through the introduction of pressurized gas into a plenum (38) overlaying hopper (30). A first pipe (12) extends vertically downward from hopper (8), and larger diameter second pipe (18) is fitted over lower end (16) of the first pipe so that an annular plenum (38) is formed between the pipes. A pressurized gas injected into this plenum increases the discharge rate. The discharge rate can be controlled by altering the pressure of the gas, and the flow can be rendered intermittent by valve (36) at the hopper's outlet.
