1. A method for comminuting a polycrystalline silicon rod, comprising:
locating the polycrystalline silicon rod on a base; and adjusting the silicon rod between at least one movable comminuting tool and at least one immovable anvil such that the at least one comminuting tool contacts a region of the silicon rod and such that the silicon rod contacts the at least one anvil, wherein the anvil and the silicon rod have precisely one point of contact and that surface of the anvil which contains this point of contact is curved; wherein a longitudinal axis of the comminuting tool is adjusted to be at one of:
a transverse axis of the silicon rod, which transverse axis runs through a rod center of the silicon rod,an axis of the silicon rod, wherein the axis is parallel to the transverse axis and is at a distance of up to 30% of a diameter of the rod from the rod, andan axis which is parallel to the longitudinal axis of the comminuting tool and is at a distance of up to 30% of the diameter of the rod from the longitudinal axis of the comminuting tool, subsequently starting a striking momentum, wherein, when the striking momentum is started, the comminuting tool and silicon rod are not touching, whereupon the comminuting tool effects a comminution of the silicon rod. |
