摘要：
An apparatus for fracturing polycrystalline silicon has: a pair of rolls which are rotated in a counter direction each other around parallel axes; and a plurality of fracturing teeth protruding outward radially from outer peripheral surfaces of the rolls and having variant heights. In the apparatus for fracturing, the fracturing teeth are arranged so that higher teeth among the fracturing teeth and lower teeth among the fracturing teeth are alternately rowed at least along a circumferential direction or a width direction of the rolls; and the fracturing teeth are arranged so that a tip of the higher tooth of the one roll and a tip of the lower tooth of the other roll are opposed to each other at a position in which the fracturing teeth of each rolls are closest to each other, so that the apparatus fractures fragments of polycrystalline silicon between the rolls.
