Abstract: Methods and apparatus for separating polysilicon powder from a mixture of granular polysilicon and polysilicon powder are disclosed. The method includes tumbling the polysilicon material in a tumbling device while flowing humidified sweep gas through the tumbling device. Also disclosed are compositions including granulate polysilicon or polycrystalline silicon, in some examples, including a coating layer consisting essentially of water.

Abstract: Methods and apparatus for separating polysilicon powder from a mixture of granular polysilicon and polysilicon powder are disclosed. The method includes tumbling the polysilicon material in a tumbling device. The tumbling device includes a tumbler drum having one or more lifting vanes spaced apart from one another and extending longitudinally along an interior surface of the tumbler drum. The lifting vanes facilitate separation of polysilicon powder and granules as the tumbler drum is rotated about its longitudinal axis of rotation.

Abstract: This disclosure concerns embodiments of an annealing device and a method for annealing flowable, finely divided solids, such as annealing granular silicon to reduce a hydrogen content of the granular silicon. The annealing device comprises at least one tube through which flowable, finely divided solids are flowed downwardly. The tube includes a heating zone and (i) a residence zone below the heating zone, (ii) a cooling zone below the heating zone, or (iii) a residence zone below the heating zone and a cooling zone below the residence zone. An inert gas is flowed upwardly through the tube. The tube may be constructed from two or more tube segments. The annealing device may include a plurality of tubes arranged and housed within a shell. The annealing device and method are suitable for a continuous process.

Abstract: Fine particulate material is separated from a mixture of coarse particulate material and fine particulate material by passing sweep gas through the chamber of a rotating tumbler drum that contains an introduced material that is a mixture of coarse particulate material and fine particulate material. In particular, polysilicon powder may be separated from granular polysilicon. Seals are present, at locations where gas-conveying parts of the apparatus move relative to one another, to block the escape of sweep gas to the atmosphere surrounding the apparatus. A downstream seal extends between a stationary exhaust duct and an exhaust tube that rotates with the tumbler drum. The seal is protected by a flow of clean flush gas that is delivered to a gap between the exhaust duct and the exhaust tube.

Abstract: An oscillatory feeder operable to convey a flowable solid material has a tubular body and a displaceable body segment. The tubular body has at least one first end, at least one second end opposite the first end and a displaceable body segment between the first and second ends. The displaceable body segment has a first fixable location positionable at a first fixed location and a second fixable location positionable at a second fixed location. The actuator is attached to the displaceable body segment and controllable to cause selected displacement of the body segment and attached actuator and corresponding selected flow of solid material within the displaceable body segment in a feed direction extending generally from the first end to the second end.

Abstract: A feeder operable to convey a divided solids material comprises a conduit and an actuator. The conduit has a hollow body with a length, a first end, a second end opposite the first end and a displaceable body segment defined along at least a portion of the length. The displaceable body segment has at least a first fixable location positionable at a first fixed location. The actuator is positioned to apply force to the conduit and is controllable to cause selected flow of divided solids material in a feed direction extending generally from the first end to the second end. Methods are also disclosed.
