There is herein described an apparatus and method for feeding bulk material. More particularly, there is described an apparatus and method for feeding bulk material such as bulk solids which provides a constant and reliable feed of material.

A feeding device with a stirring mechanism includes a device body and a nautilus-shaped turning wheel. The device body includes a base and a storage barrel disposed above the base. A bottom of the storage barrel includes an opening. The nautilus-shaped turning wheel is pivoted on the base and accommodated in the opening. The axial direction of the opening is perpendicular to the axial direction of the nautilus-shaped turning wheel. An outer periphery of the nautilus-shaped turning wheel includes a spiral arc edge with a thickness gradually decreased along a rotating direction and a stepped wall formed between two ends of the spiral arc edge. Therefore, the feeding device has the function of stirring the feed and removing the jamming.

A system and method for separating granular particles according to particle size, and more particularly enhance ore grades by removing unwanted material. The system (10) comprises means (11) for transporting granular material (12) comprising multiple sized fractions with gradation of the particles according to particle size between relatively fine fractions and relatively coarse fractions, in a direction having a horizontal component; and subjecting the granular material (12) to vibration while being so transported to induce some separation of particles according to particle size. The system (10) further comprises means (13) for causing the granular material (12) to subsequently move as a granular flow (14) along a curved path (15) under the influence of gravity to further induce separation of particles according to particle size. The system (10) still further comprises means (16) for dividing the granular flow (14) moving along the curved path (15) into different streams (17) according to their trajectory.

A doser assembly includes a hopper assembly configured to receive filler material, a vibration transmission assembly coupled to the hopper assembly, and a paddle in a hopper opening that extends through the hopper assembly. The vibration transmission assembly includes a shaft that is configured to rotate around a central rotation axis, an eccentric that is fixed to the shaft and has a center that is radially offset from the central rotation axis, a connecting rod that is pivotably connected to the center of the eccentric, and a bracket that is pivotably connected to the connecting rod. A first end of the paddle is pivotably coupled to the hopper assembly at a paddle pivot joint. The paddle is fixed to the bracket of the vibration transmission assembly separately from the hopper assembly. The vibration transmission assembly is configured to cause the paddle to reciprocatingly pivot around the paddle pivot joint.

A raw material supply device and a device for processing electronic and electrical device part scraps, which can control dropping positions of a raw material containing substances having different shapes and specific gravities, and a method for processing electronic and electrical device part scraps using those devices. The raw material supply device includes a receiving port, a discharge port, a first guide surface, and a second guide surface on a surface opposing to the first guide surface. The processing device includes a first conveying unit, a raw material supply device, a second conveying unit, and a pyramid-shaped disperser. The processing method comprises a sorting step, wherein the sorting step comprises dropping the electronic and electrical device part scraps onto a plurality of dispersion surfaces of a pyramid-shaped disperser, and dispersing the electronic and electrical device part scraps in a plurality of directions on a conveying surface.

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.

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.

Provided are embodiments of a chute for articles, in particular packages and/or consignments, having a chute base for the article to slide down and comprising at least two chute-base sections is described, wherein the at least two chute-base sections form a height offset between one another, wherein at least one guiding device is provided between the at least two chute-base sections in order to guide the article from one chute-base section to the next chute-base section, wherein the at least one guiding device has a vertically adjustable free end that points in the direction of the next chute-base section, and wherein the guiding device has, transversely to the chute base, a plurality of finger elements that are arranged alongside one another and are at least in part vertically adjustable independently of one another.

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.

An ore chute system, comprising: a chute box for collecting material and having a chute opening formed therein for discharging the material therethrough; a chute press gate mounted over the chute opening and moveable between an opened position to allow discharge of the material from the chute box and a closed position to prevent discharge of the material from the chute box; a chute press gate actuator coupled to the chute press gate and controllable to move the chute press gate between the opened position and the closed position; and, a chute press gate counterweight system coupled to the chute press gate and configured to move the chute press gate from the opened position to the closed position upon failure of the chute press gate actuator.
