    Abstract: El invento se refiere a un procedimiento para determinar el comportamiento en transporte de materiales granulares durante el transporte neumático, donde (A) la probeta de material granular es colocada en un canal transportador, (B) después del canal transportador la probeta de granulado es introducida a través de un inyector en una corriente regulada de aire, (C) la probeta de granulado fluye a través de un tramo de transporte, y (D) la probeta de granulado es medida en un espectrometro de difraccion láser, donde en el paso (B) la probeta de granulado se introduce a través de un inyector Venturi. El dispositivo para la realizacion del procedimiento comprende: - un canal de transporte para la introduccion de granulados en el tramo de transporte, - un canal de transporte para la introduccion de granulados no expuestos a solicitacion en el espectrometro de difraccion láser, - una válvula de regulacion de la corriente de aire, - un inyector Venturi, - un tramo de transporte, y un espectrometro de difraccion láser.

    Abstract: An apparatus (20) and method for dispensing fine particle material from a container (128) such as a flexible intermediate bulk container (128). The invention includes a dispensing assembly (20) that has a dispensing device that is secured to an outlet tube (134) of the container (128). Securement is achieved by a strap member (136) wrapped about the container's outlet tube (134) and a clamping casing (62) and/or by an inflatable member (80) that expands outward from the clamping casing (62). The casing (62) surrounds a transport tube (28) which is axially shiftable following securement of the clamping casing (62) to the outlet tube (134). A head piece (22) with gas cavity (40) and radial (50) and oblique (52) extending ports is provided at the end of the transport tube (28). The dispensing device (20) is inserted into the outlet tube (134) below a blocking member (146) provided at the base of the outlet tube (134). Following attachment of the outlet tube (134) to the clamping casing (62), the blocking member (146) is released. The transport tube (28) is then released from a first position, shifted and then fixed in a second position. The second position places the head (22) of the dispensing device (20) into the main compartment of the container (128) and above the released blocking member (146). At this location gas, is injected through the ports (50,52) and product is drawn out through the interior (32) of the transport tube (28). In an alternate embodiment, there is used, either alone or in combination with the headpiece (22), an injection branch (302) for directing a jet of air down the central axis of the transport tube (28). In another embodiment, a constricted member having a venturi configuration (314) is provided in the same area within the transport tube (28) as the outlet of the injection branch.

    Abstract: The invention relates to a method of determining the transport behaviour in the pneumatic transport of granular materials, in which (A) the sample of granular material is introduced into a feed chute, (B) the sample of granular material is, after the feed chute, introduced via an injector into a regulated stream of air, (C) the sample of granular material flows through a transport section and (D) the sample of granular material is measured in a laser light scattering spectrometer, wherein in step (B) the sample of granular material is introduced via a Venturi injector. The apparatus for carrying out the method comprises a feed chute for introduction of granular materials into the transport section, a feed chute for introduction of unstressed granular materials into the laser light scattering spectrometer, an air flow regulating valve, a Venturi injector, a transport section and a laser light scattering spectrometer (4).
