A distribution ramp system for a dry product applicator with a pneumatic conveyance system is provided which lifts product that drags along a bottom surface(s) of a delivery line's wall(s) back into a main central or primary airflow portion that carries the product downstream through the pneumatic conveyance system. The system may include a ramp that nests against a bottom wall of the delivery line with a narrow front and wide back so the ramp presents a gradual wedge facing toward the incoming upstream airflow entrained with particulate material of the product, urging particulate material dragging on the bottom wall to lift away from the bottom wall and toward reentry into the primary airflow portion.

The invention provides a pneumatic conveying system having a series of supply lines with at least portions of the lines being wear resistant to extend the useful lifespan of an agricultural product delivery applicator. The wear resistant supply line(s) may be made from a hard material and have a curve(s) defined by angled or mitered segments that are welded or otherwise joined to collectively provide the curve(s) The wear resistant supply lines may be at least partially reinforced by way of, for example, welded or other build up wear resistant material(s) at high wear zones of the supply lines.

A powder-dispensing device in the form of a dense-phase powder pump or of a powder injector is provided to deliver coating powder from a powder reservoir to a powder-spraying device. To make the spray coating operation easier for the customer and to be able to make it more cost-effective, without having to compromise on good coating quality and good coating efficiency, a control device is integrated in the powder-dispensing device or is connected, in particular directly, to the powder-dispensing device and is designed to establish at least one parameter that is characteristic of a spray coating procedure carried out with the powder-coating device.

A conveying system for pneumatically conveying plastic granulate comprises a feed location, at which the plastic granulate is fed into a conveying line by pressurized conveying gas, a target location, in conveying connection with the feed location, for moisture contained in the conveying gas, and a condensation tempering unit, which is arranged along a section or sections of the conveying line, for making the conveying line such temperature to at least partial condensation of moisture contained in the conveying gas to form a sliding film on an internal wall of the conveying line.

The present invention provides a method of airflow transportation of methionine that can minimize the crushing of methionine, which is characterized in that when methionine is transported as airflow using carrier gas, the flow state of methionine is a low concentration floating flow type, and the mixing ratio of methionine and carrier gas is in the range of 4 to 10 kg-methionine/kg-carrier gas. In the method of airflow transportation of methionine of the present invention, if the D50 of methionine is in the range of 150 to 425 μm, the increase rate of the fine powder can be suppressed to 1.5% or less by maintaining the mixing ratio at 4 to 10 kg-methionine/kg-carrier gas, and can be suppressed to 1% or less by maintaining the mixing ratio at 5 to 10 kg-methionine/kg-carrier gas.

Methods and apparatuses for conveying particulate material are described. A particulate material conveying apparatus may comprise a slide duct having a slide duct axis. The slide duct may comprise an interior region, and the interior region may have a top third interior region, a middle third interior region, and a bottom third interior region. The top third interior region is disposed above the middle third interior region and the middle third interior region is disposed above the bottom third interior region. The duct further defines an opening. An air movement mechanism may be connected to the duct an configured to move air through the opening into the slide duct in a direction of the slide duct axis such that a greater amount of air exits through the bottom third interior region than either of the top third interior region or the middle third interior region.

The present invention is a new apparatus to efficiently reclaim cement from a horizontal warehouse. This new reclaiming apparatus combines a mechanical cement reclaiming machine, a U Reclaimer Utility Device Apparatus, together with a reduced amount of open air slides, cement is pushed by a rotating chain with rakes on said reclaiming machine, cement is further fluidized through a porous media with low pressure air, cement flow is achieved by sloping said air slides to match the fluidized angle of repose of the powdered material. Further, the present invention introduces a conveying system, composed by a cascade of enclosed air slides and elevator machines, to convey the cement from the reclaiming area to the dispatch hopper. The introduction of these components, together with traditional cement stacking methods and dispatch systems, provides for a highly efficient manner of storing and reclaiming material from a horizontal storage facility.
