A continuous asphalt mixture production plant based on double-horizontal-shaft forced mixing includes a cold aggregate bin, a continuous aggregate conveying and metering system, a drying drum, an aggregate elevator, a double-horizontal-shaft continuous mixing host, a continuous asphalt metering and conveying system, a continuous powder conveying and metering system and a finished product bin. The double-horizontal-shaft continuous mixing host includes a first double-horizontal-shaft mixing cylinder and a second double-horizontal-shaft mixing cylinder connected in series. The first double-horizontal-shaft mixing cylinder is provided with an aggregate inlet, an asphalt inlet, a powder inlet and a first discharging port, and the second double-horizontal-shaft mixing cylinder is provided with a mixture inlet and a second discharging port. The aggregate inlet, the asphalt inlet and the powder inlet are respectively connected with an outlet of the aggregate elevator, the continuous asphalt metering and conveying system and the continuous powder conveying and metering system correspondingly.

The invention relates to an apparatus for the continuous production of a particulate adsorption product, the apparatus comprising: a mixing drum having an elongated cavity for receiving a particulate adsorbent material, an adsorbent inlet and a product outlet, wherein the mixing drum is arranged such that the cavity is inclined in flow direction of the particulate material, and wherein the cavity comprises an initial transport zone adjacent to the inlet and a mixing zone following the initial transport zone; a rotating member extending through the cavity in a longitudinal direction, wherein the rotating member comprises a helical conveying blade at longitudinal positions corresponding to the initial transport zone and mixing instruments at longitudinal positions corresponding to the mixing zone; and one or more injection nozzles for injecting a liquid adsorbate to the mixing zone. The invention further relates to a process for the continuous production of a particulate adsorption product using such apparatus.

A fluid mixing system includes a support housing having an interior surface bounding a chamber. A flexible bag is disposed within the chamber of the support housing, the flexible bag having an interior surface bounding a compartment. An impeller is disposed within the chamber of the flexible bag. A drive shaft is coupled with the impeller such that rotation of the drive shaft facilitates rotation of the impeller. A drive motor assembly is coupled with the draft shaft and is adapted to rotate the drive shaft. An adjustable arm assembly is coupled with the drive motor assembly and is adapted to move the drive motor assembly which in turn moves the position of the drive shaft and impeller. An electrical controller can control movement of the adjustable arm.

A microcarrier forming apparatus includes a tank having an inner periphery. A plurality of spoilers is disposed on the inner periphery of the tank. A spray generator includes a spraying end facing an interior of the tank. A stirrer includes a shaft and a fluid driving member. The shaft includes a central axis inclined from a horizontal plane. The fluid driving member is coupled to the shaft and is disposed in the interior of the tank.

A homogenizer for homogenously blending a feedstock includes a separator, an agitator and a hopper integrated as a single unit in a common housing. The separator receives a material feed, in the form of a fluid medium carrying a composite feedstock, and separates the composite feedstock from the fluid medium. The agitator receives the separated composite feedstock from the separator, and mixes the composite feedstock to yield the homogenously blended feedstock. The hopper receives the homogenously blended feedstock from the agitator and holds the homogenously blended feedstock for release to either a processing machine or a storage container. The homogenizer is controlled by one or more control units that use signals received from a sensor in the hopper to control the delivery of a material feed to the homogenizer, and the flow of feedstock therethrough.
