A build material conveyor is disclosed. Such conveyor comprising an auger to transport build material in a substantially vertical direction wherein the conveyor further comprises a set of wall elements selectively positioned to, in a first position occupy part of the volume of the auger.

A grain dryer is a system and means for drying grain having a grain conveyor and pair of blower motors. A first blower motor has a heat exchange while a second blower motor has a cool air exchange. A screen covers the conveyor to ensure the grains stay in position. Grain is moved along the system by means of an auger.

A system and related method of applying forage treatment material to harvested forage is provided. The method can include harvesting forage, rotating a flexible auger in a bin and in a curved or angled part of a tube to convey a granular treatment material toward harvested forage moving in a chute to mix the material with the harvested forage. The system can include a flexible auger having a helical blade that extends around an auger central passageway. The auger rotates and augers the granular treatment material with the blade out of the bin. The auger can extend into a curved portion of the tube, taking on a curved configuration extending into the curved portion so that the auger extends along a curvilinear axis and includes a curvilinear portion that is rotationally constrained in the tube.

A divider system for diverting objects from an infeed lane into one or more discharge lanes includes a dividing screw set, a discharge screw set, and a diverting mechanism. The dividing screw set conveys a sequence of objects to an output end of the screw set where the objects are divided by rotation of the dividing screw set and outputted alternately to first and second discharge screws of the discharge screw set to form a first series of objects conveyed by the first discharge screw and a second series of objects conveyed by the second discharge screw. The divider system includes a diverting mechanism which can be selectively actuated to divert objects from one discharge screw to the other discharge screw to form a diverted group.

A flowback tank cleaning system and method is described. A flowback tank includes a self-cleaning system. A flowback tank cleaning method may include moving solid debris collected at a bottom of a collection section of a flowback tank towards a lift auger using a cleaning auger or a conveyer belt extending along a length of the collection section, the bottom of the collection section including an angled trough, funneling solid debris towards the cleaning auger or conveyor belt by placing the cleaning auger or conveyor belt at a base of the angled trough, spraying fluid downward through a series of fluid outlets, removing the sand so moved by the cleaning auger or conveyer belt from the flowback tank using the lift auger, and removing the fluid from the flowback tank using a drain manifold below the cleaning auger or conveyer belt.

A filter unit is connected between a tray and a discharging duct of a spiral conveyor. The filter unit includes a first filter (perforated metal) that is fixed at a position close to the outer periphery of a conveying spiral, and a second filter (mesh filter) that rotates on the outside of the conveying spiral and the first filter. A washing nozzle sprays a washing liquid on the second filter. The chips captured by the first filter are scraped by the rotating conveying spiral and delivered back to the conveying path and the chips passing through the first filter but captured by the second filter are removed by the washing nozzle and delivered back to the conveying path. The washing liquid is sprayed at a predetermined angle from the washing nozzle and collides with vanes arranged on the outer periphery of the second filter and provides rotational force on the second filter.

Aspects of the disclosure provide a screw conveyor for discharging solids from a solid/liquid waste stream is provided and comprises a cylindrically shaped screen segment including perforated screen segments and an inlet for receiving a stream including solid and liquid materials, the perforated portions configured to permit liquids and smaller materials to pass therethrough. The conveyor includes a rotor auger disposed within the screen segment and includes helical flights configured to move solid materials larger than perforations on the perforated screen to move vertically when rotated. A drive motor is included to rotate the rotor auger and anti-rotation elements are disposed radially outward between adjacent perforated screen segments and configured to prevent rotation of solid materials to permit the rotor auger to move the solid materials in an axial direction of the rotor auger rotation.
