A test apparatus for measuring the cohesive, adhesive and frictional properties of bulk solids has a bulk solid sample confined between two essentially parallel plates with a single load applied that produces both shear and normal stress and strain to the bulk solid in a manner that nearly uniformly distributes stress throughout the granular solid test region. The apparatus has a close proximity of the plates compared with the length of the plates in the direction of shear, the design of a load hanger to produce a resultant load near the shear plane, the roughening of any surface in contact with the solid that is not intended to have shear on it and involves one-directional movement of the parallel plates with respect to each other and the control of both the direction and magnitude of the applied load relative to the parallel plates. A test method uses the apparatus to measure the unconfined yield strength angle of internal friction and steady state deformation effective angle of internal friction with a single test. A test method uses replacement of the lower part of the test sample with a plate of material that the bulk solid may be required to slip on and measures the friction angle and adhesion of the bulk solid on the plate of material.

A comminuted cellulosic fibrous material treatment vessel assembly includes a substantially vertical vessel having a top, bottom, and outlet, and through which the material flows in a flow direction. The vessel preferably has a substantially cylindrical wall with at least one diameter-changing transition between the inlet and the outlet. A screen assembly is preferably provided at or just past the transition. The screen assembly comprises one or more annular screen surfaces diverging in the flow direction of the material, the angle of divergence being between about 0. 5-10° to the vertical, and preferably substantially continuous. Providing such a screen assembly reduces the radial compression of material thereon, and increases the volume and rate of liquid that can flow through the material and be removed through the screen surface compared to a non-diverging screen surface (that is a right-cylindrical surface). The screen surface has openings of substantially uniform size, and preferably with a substantially uniform percentage of open area, in the flow path.

Apparatus and a test method for bench scale determination of whether a particulate material will flow under the action of gravity alone from an outlet in the bottom of a container. The apparatus includes a test cell having inclined conical side walls, and that is closed at its larger end by a plug having an inwardly-facing surface that is concave and conforms to a coaxial cone. In this way, cylindrical surfaces are avoided, and the shape of the space within the test cell offers minimal interference with the plastic stress field of the material. This testing method includes the novel step of inverting the test cell after consolidation of the test material but prior to application of the failure load.

A first body has a cylindrical section that is adjacent a conical section so as to form a constricted passage through which granular solids are forced under pressure. Passage through the constriction results in the application of shear forces to the granular solids which degrades some of the particles to create fines to fit between the larger particles and which induces interparticle motion that facilitates the compaction process. After passing through the constriction, the compacted solids are received in a cylindrical receiving chamber, into which a piston can be inserted for the application of direct compression forces. In a preferred embodiment, the granular solids are forced through several constricted passages in sucession, resulting in several stages of compaction prior to the final stage of direct compression.

A bulk granular solids gravity flow curing vessel comprises an upper curing unit having a top opening for receiving particulate solids, a lower curing unit coupled to receive particulate solids from the upper curing unit, and at least one of the upper and lower curing units including a first intermediate section having substantially vertical sidewalls, a first hopper positioned to receive the particulate solids from the intermediate section, and a first velocity adjustment means positioned in the intermediate section and/or the first hopper. A bulk granular solids gravity flow curing vessel comprising a first section having substantially vertical sidewalls, a first hopper positioned to receive particulate solids from the first section, and a first velocity adjustment means positioned in the first section is also described. A bulk granular solids gravity flow curing vessels comprising a first section having substantially vertical sidewalls, a first velocity adjustment means positioned in the first section and having non-vertical sidewalls, a second section having non-vertical sidewalls, second velocity adjustment means positioned in the second section and having substantially vertical sidewalls is further described.

An improvement to a hopper to promote the flow of solid particulate material includes mounting one or more walls of the hopper for limited oscillatory motion in a direction parallel to the wall and perpendicular to the desired flow direction, and then providing an actuator connected to the remainder of the hopper to impart such motion to the wall. The relative motion between the moving wall and the particulate material effectively rotates the friction force to the direction of relative motion, leaving the friction in the desired flow direction approaching zero. As a result, downward flow can occur on walls that are only shallowly inclined. The improvement is applicable to hopper-like structures in railroad cars and ships, where it facilitates discharge onto moving conveyors.

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.

An elongated, generally vertically extending reactor vessel for the production of hypochlorous acid by the mixing and reaction of a liquid alkali metal hydroxide and a gaseous halogen is provided with solids discharge handling apparatus connected to the bottom to remove the solid by-product. The discharge handling apparatus uses the solids to effect a seal to prevent the intrusion of outside air into the reactor and the escape of halogen and product gas to the outside atmosphere.

The interface is an apparatus that is attached to the outlet of a hopper to assist and control the discharge of particulate material onto the loading surface of a feeder, such as a moving belt. The interface results in a saving of 50 to 75 percent in the power required to drive the feeder. Three structural innovations contribute to this saving in power. First, a plate that extends vertically and in the direction of movement of the feeder is introduced into the stream of material within the interface to reduce downward pressure on the loading surface of the feeder. Second, the lower edge of the strike-off plate is arched upwardly, which reduces the power required for maintaining the shearing action. Third, the interface is provided with vertical skirts that prevent lateral spreading of the material so that a narrower feeder can be used.

A chip bin construction, ideally suited for bins having a maximum diameter of twelve feet or more, uniformly discharges chips, after steaming, without the necessity of a vibratory discharge. A hollow transition portion is provided between a hollow substantially right circular cylindrical main body and a rectangular discharge. The hollow transition may have a substantially circular cross-section open top and a substantially rectangular cross-section open bottom and opposite non-vertical gradually tapering side walls. At least one feed screw may be mounted at the open bottom of the transition for cooperation with the discharge, and the feed screw(s)--or the equivalent--may provide for metering of the chips. Alternatively, the hollow transition portion may provide one dimensional convergence and side relief, and no screw feeders need be provided, in which case a conventional chip meter is used.
