PACKAGING OF POLYCRYSTALLINE SILICON

摘要

The present invention is a method of packaging polycrystalline silicon in a chunk shape. The method comprises a step of providing the polycrystalline silicon in a metering system; and a step of filling the polycrystalline silicon from the metering system, which removes fines by way of screening, into a plastic back arranged below the metering system. A weight of the plastic bag with the polycrystalline silicon introduced is determined during a filling operation. The filling operation is ended after attaining a target weight. A fall height of the polycrystalline silicon from the metering system into the plastic back is kept at less than 45 mm by use of at least one clamp device over the entire filling operation.
