Disclosed herein are reclaimer systems, troughs, and methods for selectively positioning at least a portion of an upper portion of a trough relative to a vertical axis to adjust an operative height of the trough and thereby set an overflow threshold height for the reclaimed material, wherein reclaimed material below the overflow threshold height contributes to a target reclaim rate for the reclaimer system, and wherein the trough is configured to permit overflow of reclaimed material above the overflow threshold height.

Disclosed a large-span bulk material conveying system, including a folding arm conveyor and a dike-striding elevation-type feeding conveying device. The folding arm conveyor is mainly composed of an undercarriage mounted on the ground of a stockyard, a tower body mounted on the undercarriage and provided with a gyration apparatus and a hopper, a balance arm provided with a balance trolley, a conveying arm provided with a portal frame I, a portal frame II and an unloading trolley, a tower top and other main components, wherein the balance arm, the conveying arm and the tower top are mounted on the tower body. The folding arm conveyor can rotate horizontally, and the conveying arm can be folded and retracted by controlling the wire rope by the windlass, so that the folding arm conveyor can be prevented from colliding with other devices or buildings during the rotation.

A grain storehouse includes a granary, a grain loading system, and a grain unloading system. The granary includes multiple storages arranged in a network format. The bottom of each storage is a tapered structure with a tapered surface downward, and the bottom of the tapered structure provides a switchable blanking exit. The grain loading system includes a lattice girder structure, a plurality of conveyors and multiple hoppers. The grain unloading system includes at least one conveyor that is located under the blanking exit. The present invention improves the automaticity and efficiency of grain loading and unloading of the grain storehouse, so that the grain can be transferred quickly.

A device conveying a solid material into a radially-arranged stockpile. The device has a trailer chassis, with at least one wheeled axle at a first end thereof and, at a second end thereof, means provided for attaching the chassis to a tractor in a mobile condition and for fixed mounting in an operational condition. A stacking conveyor is mounted near the first end of the chassis. A power unit for generating electrical and hydraulic power is positioned on the chassis. A feed system is mounted to the chassis and extends generally along the length thereof from the second end to the first end, to receive the solid material at the second end and transport the solid material to the stacking conveyor.

The present invention is a new method to efficiently reclaim cement from a horizontal warehouse. This new reclaiming method combines a mechanical cement reclaiming machine, together with a reduced amount of open air slides. Material is fluidized through a porous media with low pressure air. Material flow is achieved by sloping the Air slide conveyor to match the fluidized angle of repose of the powdered material. Further, the present invention introduces a conveying system, comprising a cascade of open and enclosed air slides and elevator machines, to convey the cement from the reclaiming area to a dispatch hopper. The introduction of these components, together with cement stacking and dispatch systems, is a Fully Automated Cement Horizontal Storage system and method.
