A system for mixing a fine bulk material including means defining a looped passageway including a vertically disposed, laterally enlarged section having a frusto-conically configured, lower outlet portion; means for injecting a fluid under pressure into an upper segment of such frusto-conically configured lower outlet portion to fluidize material therein; means for injecting a fluid under pressure into a lower segment of such frusto-conically configured lower portion to fluidize material therein; and means for injecting a fluid under pressure in said passageway downstream of said lower outlet portion sufficient to induce the flow of fluidized material through said passageway to an upper end of such enlarged section.

System for mixing/blending fine bulk materials

A compact, portable carrier for a flexible bag containing a comminuted material and having a bottom discharge spout, including a frame structured to encompass such bag and attach such bag in suspended relation thereto, be transported to a spaced site and be operated to jostle the material contained in such suspended bag to facilitate the discharge thereof through the spout thereof.

Bulk material handling system and carrier therefor

A system for unloading a container of bulk particulate material, having attachment means for lifting the container and a spout for discharging material therefrom, generally consisting of an unloading apparatus including a material hopper, a mobile apparatus and a carrier member including an arrangement for detachably connecting a container thereto, an arrangement for detachably mounting on a mobile apparatus and an arrangement for detachably mounting on the unloading apparatus.

System and method for handling containers of bulk particulate materials

The present invention is directed to a system and a method to unload bulk powders from large bulk containers. The system and method are particularly useful for unloading bulk cohesive powders.

System and method for unloading bulk powder from large bulk containers

An apparatus for guiding bulk material transported by a pneumatic conveying line or by gravity into a container having an access spout generally consisting of means for supporting the container; a housing mountable on the supporting means including a cylindrical side wall having a lower open end insertable into the spout of the container, a closed upper wall having an opening disposed axially relative to the side wall through which a discharge end portion of the pneumatic conveying line may be inserted, a partition formed of a filter medium disposable between the side wall of the housing and the discharge end portion when such portion is inserted through the upper wall opening of the housing, providing a closed chamber and an open chamber communicating with the lower open end of the housing, and an outlet communicating with the closed chamber; and means mounted on a lower end of the housing side wall selectively operable to engage the spout when the lower end of the cylindrical side wall is inserted into the spout for forming a seal between the lower housing end and the spout.

System for pneumatically conveying bulk materials with improved discharge arrangement

A system for pneumatically conveying a bulk particulate material generally consisting of means for holding such material, having an inlet and an outlet; a first material transport line segment including a first conduit formed of a gas permeable material having an inlet communicating with the outlet of the holding means and an outlet, defining a material flow passageway, and a second conduit formed of a gas impermeable material spaced from and encompassing the first conduit, defining a plenum; a second material transport line segment including a first conduit formed of a gas permeable material having an inlet communicating with the outlet of the first conduit of the first segment, defining a continuation of the material flow passageway, and an outlet, and a second conduit section formed of a gas impermeable material spaced from and encompassing the first conduit thereof, defining a plenum; the second segment being displaceable relative to the first segment between a first position communicating the outlet of the first conduit of the second segment with a receptacle into which the material is to be conveyed, and a second position communicating the outlet of the first conduit of the second segment with the inlet of the material holding means; means for supplying gas under pressure to the plenums, causing such gas to penetrate the first conduits to fluidize material flowing in the passageways and means for inducing the flow of material in the passageways, causing material induced therein from the holding means to be impelled therethrough.

System for pneumatically conveying bulk particulate materials

A rotary valve generally consisting of a housing having a cylindrical chamber provided with an inlet communicable with a zone of a first pressure, a first outlet communicable with a zone of a second pressure greater than said first pressure and a second outlet communicating with the exterior of said housing, a shaft journaled in the housing extending through and disposed coaxially relative to the axis of the chamber, a rotor mounted on the shaft within the chamber, between the inlet and each of the first and second outlets, having at least one set of circumferentially spaced material receiving pockets communicable sequentially with the inlet and the first outlet and the second outlet for receiving material through the inlet and discharging the material through the first outlet, and a device intercommunicating the second outlet and the exterior of the housing for diffusing the flow of gas vented from the rotor pockets through the second outlet to exterior of the housing to muffle the sound of venting gas.

High pressure rotary valve with sound reduction means

A system for pneumatically conveying bulk particulate materials generally consisting of a material transport line including a first conduit formed of a gas permeable material providing a material flow passageway having an inlet and an outlet, a second conduit formed of a gas impermeable material, encompassing and spaced from the first conduit, and a plurality of partition walls disposed between the conduits and spaced along the lengths thereof, defining a plurality of plenums; a nozzle connectable to a source of gas under pressure, inserted into the passageway for injecting gas under pressure therein to impel material disposed in the passageway toward the outlet thereof; a main gas supply line connectable to a source of gas under pressure having branch lines each communicable with a plenum; and each of the branch lines having a pressure regulating means.

A system for handling a bulk particulate material generally consisting of a vessel for holding a mass of such material; a first elongated tube formed of a gas permeable material, having an inlet communicating with such vessel; a second elongated tube formed of a gas impervious material encompassing the first tube and spaced therefrom about the periphery of the first tube; a plurality of transversely disposed, longitudinally spaced partitions disposed between said first and second tubes, forming a plurality of isolated chambers encompassing the first tube; each of such isolated chambers having means for selectively introducing a fluidizing gas therein independently of the other of such chambers, at variable volumes and pressures whereby the volume and pressure of fluidizing gas diffused through the first tube may be modulated along the length thereof; and means for injecting a flow inducing gas into the first tube.
