A system includes a pump configured to transfer a granular material out of a hopper into a transfer pipe. The pump includes an upstream portion having an upstream helical flight and a downstream portion having a downstream helical flight. The downstream portion includes a tailpiece. An outer diameter of the downstream helical flight is less than an outer diameter of the upstream helical flight, a gap between the outer diameter of the downstream helical flight and an auger housing is greater than a gap between the outer diameter of the upstream helical flight and the auger housing, a thickness of the downstream helical flight is less than a thickness of the upstream helical flight, a surface of the downstream portion has a lesser coefficient of friction than a surface of the upstream portion, or a combination thereof.

Pumping apparatus comprises a granular material pump assembly and a distributor having a distribution end for distributing granular material. The granular material pump assembly is configured to pump granular material through the distributor towards the distribution end. The distributor is configured to permit granular material to exit the distributor at the distribution end when an amount of granular material pumped towards the distribution end exceeds a threshold, for example wherein the distributor comprises a valve assembly configured to permit granular material to exit the distributor at the distribution end when the amount of granular material pumped towards the distribution end exceeds the threshold, optionally wherein the valve assembly comprises a valve configured to open to permit granular material to exit the distributor at the distribution end when the amount of granular material pumped towards the distribution end exceeds the threshold.

In a granular material supply system including a tank that stores granular material, a carrier line through which the granular material flowing out of the tank is carried to a carrier destination, and a cutout line that connects the tank and the carrier line and through which the granular material flowing out of the tank is supplied to the carrier line, a control device includes a density control unit configured to control a density of the granular material on a downstream side of a junction of the cutout line and the carrier line to a set value predetermined and a flow rate control unit configured to control a flow rate of the granular material to be supplied to the carrier destination through the carrier line to a command value instructed by the carrier destination.

Provided is an improved animal feed distribution system and components, specifically tube belt conveyor system, that provides more efficient manner of delivering feed to the animals, such as poultry by using tube conveyor belt to distribute feed in a re-circulating loop.

A cleated belt tube conveyor for conveying granular material, such as seed and grain commodities. The conveyor comprising a cleat row profile that is optimized for maximizing transfer capacity and minimizing wear. The cleat row profile may incorporate one or more of the following aspects: taller central cleat member and a slanted or clipped peripheral cleat. A cleated belt conveyor guide element, comprised of a plurality of longitudinally spaced-apart lugs that extend from an inner surface of the belt is also disclosed. A cogged roller, having a plurality of channel segments divided by drive bars, complements the guide element, increasing the power transfer and tracking ability over a cleated belt lacking a guide element. Also a baffle assembly can be disposed within the conveyor tube to limit material back flow. The baffle assembly can be configured with a belt passage aperture that corresponds to the cleat row profile.

A vacuum conveyor for conveying granular material and an intake nozzle for the vacuum conveyor is provided. The vacuum conveyor can have a vacuum section operative to create a vacuum in the housing, an intake to allow granular material to the housing, a variable length hose section and an intake nozzle. The intake nozzle can include an intake end, an output end and a body extending between the ends with a plurality of apertures passing through the body. A sleeve for the intake nozzle can be sized to fit around the body positionable in different positions relative to the body to cover and uncover the various apertures.

A single drive dual hopper conveyor system is presented having a center conveyor system and a pair of side conveyor systems that are connected to one another. A single motor is connected to the center conveyor system and drives movement of a belt within the center conveyor system. The connection of the center conveyor system to the side conveyor system causes the belts of the side conveyor systems to be simultaneously driven as the belt of the center conveyor system is driven. This arrangement eliminates the need for multiple motors. A guide at the center of the belts is configured to guide the belts through the center of the housings and prevent the buildup of grain within a cut-out section of the flights of the belt that is needed to allow access to the links of the belts to facilitate driving of the belts.

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 process is described that includes flowing a carrier fluid through a transfer line, feeding polymer pellets into the transfer line at a feed location, measuring a first pressure value of the carrier fluid at a location in the transfer line upstream of the feed location, measuring a second pressure value of the carrier fluid and polymer pellets at a downstream location in the transfer line which is downstream of the feed location, and determining a mass flow rate of the polymer pellets flowing in the transfer line based on a differential pressure between the first pressure value and the second pressure value.

A conveyor system includes a looped belt and a conveying portion cover. The belt has a conveying portion and a retreating portion movable through the conveyor system, each of the conveying portion and the retreating portion having an interior surface and an exterior surface, the exterior surface of the conveying portion configured to convey materials. The conveying portion of the belt is disposed within the conveying portion cover, the retreating portion of the belt disposed exteriorly of the conveying portion cover, and the conveying portion cover has a convex sliding surface and a tubular shape. The interior surface of the conveying portion of the belt is slidable along the sliding surface of the conveying portion cover.
