The introduction part 32 and the introduction part 31 have an uneven surface, and only the introduction part 32 may be used depending on the pulverized material. Around the upper mill 1 and the lower mill 2, there is a crushed portion 3 that is substantially parallel, and the crushed portion 3 is formed by alternately and continuously forming a plurality of concave and convex portions extending from the inside to the outside. To do.

  A drive shaft 9 is fitted to the lower die 2 to transmit the output from the motor 8. Therefore, the lower mill 2 rotates and the lower mill 2 and the drive shaft 9 are detachable. A casing 12 for dropping the pulverized pulverized material from the gap between the upper mortar 1 and the lower mortar 2 is provided. The sweeping tool rotates inside the casing 12 together with the lower mill 2 and sweeps the pulverized material into an outlet 13 provided in a part of the casing 12. A take-out chute 14 is provided outside the take-out port 13, and a container 15 for collecting the crushed material falling from the take-out chute 14 is provided below the take-out chute 14.

  In this embodiment, the locking mechanism is constituted by the locking plate 10, the machine frame 16, the rotating shaft 20, the handle 18, the handle shaft 25, and the like. The locking plate 10 can be rotated by the rotation shaft 20 with respect to the machine frame 16 to move the upper die 1 up and down. The locking plate 10 can be fixed by the handle 18 and the handle shaft 25. One of the locking plates 10 is fixed to the machine frame 16 so as to be rotatable by a rotation shaft 20, and the other is fixed by a handle 18 and a handle shaft 25.

  The upper die 1 and the locking plate 10 are connected via spherical washers 21, 22. A spherical washer (upper) 21 is attached to the locking plate 10, and a spherical washer (lower) 22 is attached to the upper die 1. Install.

  Next, the motor 8 is started and the lower die 2 is rotated (when the cooling device is attached, the cooling device is also started). Then, the pulverized material 40 is charged into the charging port 36 of the hopper 35. In order to put the pulverized material 40 into the charging port 36, the worker inputs it, or installs a charging device (not shown) and loads it with the charging device. It is preferable that the feeding device can supply a fixed amount.

  The pulverized product 40 is pulverized by the blades 5 and 6 at the introduction portion 32 between the upper mortar 1 and the lower mortar 2, and when it becomes smaller than the gap between the introduction portions 32 of the upper mortar 1 and the lower mortar 2, Move to). The pulverized material pulverized by the blades 5 and 6 moves to the crushing portion 3 and is further finely pulverized. The centrifugal force and the shape of the crushing portion 3 (recesses and protrusions extend from the inside to the outside) Then, it moves around the upper die 1 and the lower die 2 and falls to the casing 12 through the gap between the upper die 1 and the lower die 2. The fallen crushed material is guided to the take-out port 13 by the sweeping tool rotating together with the lower mill 2 and taken out to the container 15 by the take-out chute 14.

  As described above, when the spherical washers 21 and 22 are attached and operated, even when the crushing portion 3 is in a state of scoring, when the lower die 2 is pressed by the upper die 1, The upper mill 1 is also sown in accordance with the lower mill 2 and the lower mill 2 rotates with the crushed portion 3 in close contact. For this reason, the upper and lower crushed portions 3 are parallel to each other, and a uniform and fine pulverized material comes out to the outlet 13.

  With this device, tea, buckwheat, rice, millet, etc. can be processed, and pulverized products are not limited to these. The number of rotations of the lower die 2 may be changed by the motor 8 according to the type and particle size of the pulverized product.
