  • Packaging of polycrystalline silicon
    Patent number: 9550587
    Abstract: The invention relates to a process for packaging polycrystalline silicon in the form of chunks, including the following steps: (a) providing polycrystalline silicon in a metering system; (b) filling polycrystalline silicon from the metering system, which removes fines by use of screening, into a plastic bag arranged below the metering system. The weight of the plastic bag with the polycrystalline silicon introduced is determined during the filling step and the filling step is ended after the attainment of a target weight. A fall height of the polycrystalline silicon from the metering system into the plastic bag is kept at less than 450 mm by use of at least one clamp apparatus over the entire filling step.
    Type: Grant
