APPARATUS FOR SUBJECTING BULK MATERIAL TO THE ACTION OF ACCELERATED ELECTRONS

摘要

The invention relates to an apparatus comprising at least one electron beam generator (301) for generating accelerated electrons with which bulk material particles (303) can be acted on while they are in freefall, wherein the electron beam generator (301) is of annular design and in which the electrons which are emitted and accelerated by an annular cathode exit from an electron outlet window in the direction of the ring axis; wherein the annular electron beam generator (301) is arranged in such a way that the ring axis of said electron beam generator is oriented perpendicular to or at an angle of up to 45° from the horizontal, and wherein a device for separating bulk material particles is arranged above the annular electron beam generator, the bottom wall (304) of said device having at least one opening out of which the bulk material particles (303) fall and from there fall through the ring which is formed by the electron beam generator (301).
