Device for fracturing of polycrystalline silicon and a process for the preparation of fracture fragments of polycrystalline silicon adhesive

摘要

A device for fracturing of polycrystalline silicon including a pair of rollers which the opposite direction to one another rotate around parallel axes, and a plurality of fracture design teeth, which on the outwardly pointing surfaces of the rollers are arranged, and project radially outward, wherein the surfaces at the tip spherically formed therein, and the lateral surfaces are shaped conical or cylindrical, wherein the apparatus, fragments of polycrystalline silicon substituted between the rollers fracture.
