Beschreibung
Zusammenfassung:	An apparatus for fracturing polycrystalline silicon having a pair of rolls which are rotated in a counter direction each other around parallel axes; and a plurality of fracturing teeth which are provided on outer peripheral surfaces of the rolls and are protruded radially-outwardly, in which top surfaces thereof are formed spherically and side surfaces thereof are formed conically or cylindrically, and fracturing fragments of polycrystalline silicon between the rolls.
