- the particle size fixing screw 560 can be operated with a small force, the particle size adjusting plate 320 and the fixing plate 330 are fixed to each other and the position fixing state of the inner blade 200 relative to the outer blade 100 through it is small. It can be dismantled and adjusted by force. For example, when additional position adjustment is required for the particle size adjustment, when the particle size fixing screw 560 is loosened to the extent that the particle size fixing screw 560 is held together with the size adjusting plate 320 and the fixing plate 330 together, Since the pulling force of the adjusting plate 320 and the fixing plate 330 is released against each other, when the particle size adjusting plate 320 is rotated, the fixing plate 330 is also rotated together to adjust the height of the size adjusting plate 320. The height of the blade 200 is adjusted. In the state in which the height adjustment is completed, the particle size adjusting plate 320 may be fixed by tightening the particle size fixing screw 560 again.
- the particle size adjusting plate 320 allows the thickness of the pulverized product to be adjusted, and the fixing plate 330 and the particle size fixing screw 560 function to fix the adjusted fixed thickness.
- such a particle size control configuration is particularly advantageous in that it can operate separately from the configuration that separates the inner blade 200 from the outer blade 100 for cleaning the grinding blade 10. That is, even when the rotary shaft 510 is separated from the lower side with respect to the particle size control plate 320 for cleaning the grinding blade 10, it is not necessary to loosen the particle size fixing screw 560. After cleaning, the inner blade 200 is raised together with the rotation shaft 510 to fix the rotation shaft 510 again with respect to the particle size adjusting plate 320 so that the particle size is adjusted as it is. . That is, there is no need to operate the mechanism again so that the particle size of the pulverized product after cleaning is desired. Therefore, the pulverized product can be stably obtained with an even particle size.
- the vertical roller-type grinding blade and the grinder having the same have been described as an example of a coffee grinder for grinding coffee beans, but the present invention is not limited thereto and may be used for grinding various grinding objects.
