It is provided upright, and is arranged radially from the rotor shaft at regular intervals so as to have a slight inclination angle B with respect to the diameter line of the discharge plate 71. As shown in FIGS. 3 and 4, the rotor disk 21 just above the discharge plate 71 of this embodiment is used.
Is formed with a notch 21 ′ for dropping the crushed material and crushed particles to prevent the crushed material from being caught between the rotor disk 21 or the crushing blade 23 and the side wall 13 of the crushing chamber 1. For this reason, the scraping plate 72 is not disposed immediately below the notch 21 'so as not to be directly hit by the fall of the crushed material and crushed particles from the notch 21'.

And only a slight gap H exists between them, and
Since the discharge disk 71 rotates at a high speed similarly to the rotor disk 21 and a centrifugal force acts, crushed particles hardly enter the gap H. Even if crushed particles enter the gap H, the rotor shaft 3 rotates and the discharge plate 7
When 1 rotates, the centrifugal force and collision of the auxiliary scraping plate 7 provided on the lower surface of the discharge board 71 causes the auxiliary scraping plate 7 to be scraped and discharged from the gap H toward the side wall 13 of the crushing chamber 1.

1 is ejected by the centrifugal force and collision of the scraping plate 72 and discharged from the discharge port 12. Therefore, the discharging mechanism 7
There is no need to knead crushed particles between the crushing chamber 1 and the bottom wall 15 of the crushing chamber 1.
