Since the outer cylinder 34 is provided, no entanglement of fibrous garbage is caused at all.

(4) If the bolt 64 is removed and the garbage to be crushed waste adjustment disk 60 is removed and replaced with another garbage having a required diameter and fixed, the width of the discharge groove 62 is adjusted and the garbage is discharged. You can change the size of the crushed raw material.

(5) Around the lower surface of the ceiling plate 12a, the upper part around the outer cylinder 34 that covers the drive shaft 32 is equally spaced at three intervals.
Since the roller bearings 40 are fixed in the support plate 36 and provided in the space 38 between the lower end of the drive shaft 32 and the outer cylinder 34, the impeller 50 integrated with the drive shaft 32 is provided. Rotation becomes extremely smooth.

(6) The garbage to be crushed waste discharge adjusting disk 6
The garbage to be crushed is guided toward the lower center direction through the inclined surface 60a of 0, and is uniformly dropped, so that the garbage to be crushed is not scattered.

(7) On the other hand, in the invention of claim 3, the number of the fixed blades 20 is even and the number of the rotating blades 54 is odd, and in the invention of claim 4, the number of the fixed blades 20 is Is an odd number, and the number of the rotary blades 54 is an even number, so that the waste to be disposed of in the crushing chamber 12 is smoothly rotated and crushed.

(8) As described in (1) above, in addition to eliminating the need for a discharge chamber, the dust chute provided on the side surface of the cylindrical discharge chamber is also eliminated, so that the configuration is simplified and handling is extremely easy. Becomes

(9) The crushing time of the garbage to be crushed can be shortened due to the configuration, and the running cost can be reduced.
