PROBLEM TO BE SOLVED: To provide a breaker plate having a new structure that can suppress stagnation of a material flow and the like.SOLUTION: A breaker plate includes first through holes arranged on the circumference of a first circle having a first radius to form a through hole row on the outermost periphery, and second through holes arranged on the circumference of a second circle, having a second radius smaller than the first radius, arranged concentrically with the first circle. The first through hole extends so that a direction connecting the center of the first circle and an opening of the first through hole formed on one surface side and a direction connecting the center and an opening of the first through hole formed on the other surface side form a first torsion angle. The second through hole extends so that a direction connecting the center of the second circle and an opening of the second through hole formed on one surface side and a direction connecting the center of a breaker plate and an opening of the second through hole formed on the other surface side form a second torsion angle. The second torsion angle is larger than the first torsion angle. |
