A flow-through discharge assembly having a rotatable tube section and an opening through which product is discharged and a positioning apparatus for rotating the tube section between operation and non-operational conditions. When the tube is positioned in an operational orientation, grain exits through the opening for discharge from the assembly. When the tube is returned to a non-operational condition, the tube opening is blocked and grain is prevented from exiting through the opening. The tube opening may be a single elongated opening or may include multiple tube openings through which product is discharged. A method of using a rotary discharge assembly to control grain flow within a grain handling system is also disclosed.

A material handling hopper includes an integrally formed handling body that defines an inlet, an outlet, and an axis. The handling body has a seamless sidewall extending between the inlet and the outlet. The sidewall is circular in cross section in a plane perpendicular to the axis. The sidewall is curvilinear and defines a first height between an axial location of a first inner diameter and an axial location of a second inner diameter.

A transfer chute (10) for use in bulk materials handling operations, and also a methodology for designing such a transfer chute, a method of constructing the transfer chute, and a method of transferring bulk materials between two locations using the transfer chute. The transfer chute (10) comprises a chute body (11) defining a flow pathway (19), with an upper section (19a) of the flow pathway accommodating accelerating flow to maintain dense granular flow regime, an intermediate section (19b) of the flow pathway providing consolidated flow in which the flow rate is retarded in a controlled manner avoiding creation of flow turbulence, and a lower section (19c) of the flow pathway in which flow is further retarded to create a controlled accumulation and build-up of material upwardly from the lower section.

A compact dedusting apparatus for cleaning particulate materials of contaminates and has a housing defining a cleaning area in which the contaminants are removed to create cleaned particulate material with a product discharge opening through which cleaned particulate material can be discharged. The dedusting apparatus includes an infeed apparatus having a vibratory feed pan powered by a vibration generator to induce vibrations therein. The dedusting apparatus also includes a Venturi chamber to remove contaminants from the particulate material by a flow of air passing upwardly through the product discharge opening. The dedusting apparatus further includes an interchangeable carryover deflector having a chamber extension member that aligns with internal structure to control the flow of particulate material into said Venturi chamber and deflects particulate material entrained in the air flow through the Venturi chamber toward the product discharge opening. The carryover deflector incorporates an observation window to view the dedusting operation.

A hopper insert is provided for an asphalt paving machine. The hopper insert has an outlet which has first and second lateral outlet opening edges which converge toward each other from front to rear along at least a majority of the outlet length.

A gravity-fed housing for use in a gasification system is disclosed. The gravity-fed housing has a receiving end panel that forms a receive opening in a first plane. The receive opening is configured to receive a first plurality of heat carriers via gravity. The gravity-fed housing includes a siding connected to the receiving end panel. The siding forms a chamber and a discharge opening in a second plane that is parallel to the first plane. The discharge opening is offset with respect to the receive opening such that a line perpendicular to the receiving end panel that extends through a center point of the receive opening does not intersect a center point of the second opening. The siding includes a first panel that comprises a guiding surface that intersects the line and is angled toward the discharge opening.

A trim chute for a loading apparatus for loading particulate material into a container, the trim chute being configured to be engaged with the loading apparatus to direct particulate material into the container, the trim chute being moveable with respect to the loading apparatus during loading, movement of the trim chute effecting a change in flow of the particulate material into the container.

A compact modular mobile aggregate processing system configured with no stand-alone inter-plant conveyors for decreasing the footprint of the system and an infinitely adjustable flow diverter(s) for increasing the control of and variation of output characteristics of the system; the system further including specialized folding conveyors.

An additive manufacturing system can include a powder dispenser; a gate adjacent to the powder dispenser; a recoater blade system; and a control operable to move the gate with respect to the powder dispenser to selectively dispense powder from the powder dispenser.

A hopper apparatus comprises a movable wall comprising opposing walls movably connected to a support assembly and oriented at acute angles relative to a central vertical axis of the support assembly, and movement control devices configured and positioned to move the opposing walls along the support assembly to control dimensions of a discharge outlet at least partially defined by converging ends of the opposing walls; a liner assembly comprising liner structures at least partially overlying inner surfaces of the opposing walls and configured to remain at least partially stationary relative to the opposing walls during movement of the opposing walls; and pressure sensors between the inner surfaces of opposing walls and portions of the liner structures thereover. A bulk solids processing system and a method of processing a bulk solid are also described.
