Abstract:
A technology for material separation is provided. The technology enables an output of a first material from a rotary lifter. The technology enables a direction of a fluid stream onto the first material in flight based on the output of the first material such that the first material is separated into at least a second material and a third material. The technology enables a conveyance of the second material away from the rotary lifter. The technology enables a removal of the third material via a vacuum port.
Abstract:
A rotary vacuum drum drying system is described. The system may include a plurality of sensors and a control system operatively coupled with the plurality of sensors. The control system includes a processing device to monitor a plurality of parameters of the vacuum drying system received from the plurality of sensors and automatically adjust one or more of the plurality of parameters based on the monitor of the plurality of parameters.
Abstract:
Provided is an indirectly heating rotary dryer which has achieved enhanced energy-saving performance by reducing heating tubes non-contacting with material to be dried and reducing power required for rotation even when a hold up ratio is increased.Specifically provided is an indirectly heating rotary dryer having four partition walls 16 extended respectively along an shaft center C in an inner space of a rotating shell 10 at angle intervals of 90 degrees in the vertical and horizontal directions. The four partition walls 16 partition the inner space of the rotating shell 10 at a lateral section of the rotating shell 10 into four approximately-sector-shaped small spaces K respectively extended along the shaft center C. Heating tubes 11 are aligned in the rotating shell 10 in three lines extended respectively in parallel to the shaft center C of the rotating shell 10. The heat tubes 11 heat and dry the material H to be dried by supplying heated steam to the heating tubes 11 and performing heat exchange with the material H to be dried in the rotating shell 10.

Abstract:
A centrifugal drier drum for wet granular material has a peripheral drying wall arranged for rotation about its axis and an entry part for receiving the material to be dried and directing this material to within the drum. The entry part is fixed to the wall of the drum by a number of supports. Material fed to the drum impacts the entry part at an impact zone, and is received within the drum at a projection zone. An annular retaining space for retaining the material to be dried is formed at both the impact zone and the projection zone such that the circulating material strikes the surfaces of material retained in these retaining spaces.
Abstract:
A rotary drier apparatus for drying semiconductor wafers within a vessel. The rotary drier apparatus has a turntable driven by a motor, support plates mounted on the turntable, cradles suspended pivotally from the support plates with the aid of a rotary shaft, and a stopper for stopping the cradles from touching each other in a nonrotating state. The centers of gravity of the cradles are located outwardly of a portion just under the pivotal axes of the cradles.
Abstract:
Low-rank coals, such as lignite, are dried by evaporating interstitial water therefrom in a superheated steam flow countercurrently passed through a sealed rotary cylindrical vessel. A composite steam discharged from the vessel is partially condensed to remove an amount of water therefrom substantially equal to the amount of water removed from the coal, with a resultant flow of residual steam reheated and returned to the cylindrical vessel for further drying of low-rank coal.
Abstract:
A method and apparatus for processing particulate material charged into a rotary cylindrical vessel (12) having its axis inclined to the horizontal so that one end thereof is raised relative to the other end, and having a respective annular cover plate (16,18) at each end defining a central opening at its end (17,19), the material being charged through the opening (17) at the one end thereof and caused to progress along the vessel (12) and discharge therefrom through the opening (19) at the other end by rotation of the vessel (12). Gas for processing the material is passed into the vessel (12) during rotation of the latter, the gas being supplied from a source thereof, via a supply pipe (34), and discharged within the material (38) in the vessel (12) through port means (44,48) of at least one discharge conduit (42) which is in communication with the supply pipe (34), extends longitudinally within the vessel (12) and is fixed against rotation with the vessel (12); the quantity of material (38) progressing along the vessel (12) being sufficient to cover the at least one conduit (42).
Abstract:
A transmissionless driving arrangement for rotary drums in which at least one support for the drum is constituted by a slide ring which is carried by stationary slideshoes or rollers and surrounds the drum to which it is attached, the rotor and the stator of an electric motor which is utilized for rotatably driving the drum surrounding the body of the drum.
