A grinding apparatus and a grinding system capable of efficient and superior grinding performance prevent the falling of a belt during the grinding of an edge surface thereof. The apparatus includes two rotating bodies 31 and 32 each having segment brushes 4, 4, . . . attached in the circumferential direction at the edge thereof. The rotating bodies 31 and 32 are rotated in the same direction. The tip of the segment brushes 4, 4, . . . is opposed to one edge surface of a belt b stretched between a driving roller 21 and a driven roller 22. The segment brushes 4 of the two rotating bodies enter toward the belt b at appropriate locations on the one edge surface, such that the falling of the belt can be prevented. A grinding apparatus 1 includes a grinder 3 consisting of the rotating bodies 31 and 32, and a holder consisting of the rollers 21 and 22 and a casing 23 by which the rollers are rotatably supported. A plurality of such grinding apparatuses 1 are disposed at regular intervals, whereby a grinding system 10 is constructed.
