Abstract: Reduction of contamination and the proportion of fines fractions in the packaging of rod form polysilicon is achieved by directly filling a plastic bag with polysilicon from a cleaning bowl by a rotating motion which causes polysilicon chunks to slide into the bag.

Abstract: Foreign objects in a conveyed product stream of granular or chunk polysilicon is effected by identifying the foreign objects by eddy current sensors in the conveyor by which the granular or chunk polysilicon is being conveyed.

Abstract: Granular polysilicon is fed into a screening plant, divided into two or more fractions by means of one or more screen surfaces, and thereby classified and dedusted wherein a throwing motion of the granular polysilicon in the screening plant removes adhering dust particles from the granular polysilicon, the removed dust particles are taken off from the screening plant by means of a gas flow supplied to the screening plant, and the screening plant is of gas-tight design and supply and takeoff of the gas flow are effected such that the screening plant is at a positive pressure compared to the surroundings.
