Summary: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. L'invention concerne des procédés et un appareil de séparation de poudre de silicium polycristallin à partir d'un mélange de silicium polycristallin granulaire et de poudre de silicium polycristallin. Le procédé comprend le culbutage du matériau de silicium polycristallin dans un dispositif de culbutage. Le dispositif de culbutage comprend un tambour culbuteur ayant une ou plusieurs aubes de levage espacées les unes des autres et s'étendant longitudinalement le long d'une surface interne du tambour culbuteur. Les aubes de levage facilitent la séparation de la poudre et des granules de silicium polycristallin à mesure que le tambour culbuteur tourne autour de son axe longitudinal de rotation.
