よい。As shown in the figure, a plurality of discharge holes 2 are provided in the screen main body 1. In the screen main body 1 of this example, the discharge holes 2 adjacent in the lateral direction (axial direction of the rotary blade) are substantially parallel. Therefore, the discharge holes 2 in the circumferential direction are arranged in a staggered manner (only a part is described). The arrangement of the discharge holes 2 may be set according to the size of the processed material or the crushed material.

The discharge holes 2 are connected by a discharge groove 3. As described above, the direction in which the discharge holes 2 are connected is preferably the circumferential direction of the screen S, which is the same direction as the direction of rotation of the blade, and the object to be crushed can be effectively discharged by the rotating blade 54. The discharge holes 2 may be connected diagonally.
【００１５】また、排出溝３でつなぐ排出孔２の数は特
