Here, first, when the adjusting plate 13 is at a higher position where the pushing column 141 contacts the continuous stepped portion 131, the adjusting plate 13 drives the milling base 12 relative to the The grinding wheel 11 is displaced toward the first bearing 14 so that the grinding distance 111 between the grinding seat 12 and the grinding wheel 11 becomes larger. On the contrary, when the adjusting plate 13 is at a lower position where the pushing column 141 contacts the continuous stepped portion 131, the adjusting plate 13 drives the grinding base 12 to move in the reverse direction and makes the grinding distance 111 smaller.

In addition, the grinding mechanism 10 of the present invention can be used to grind food materials or coffee beans. When the grinding distance 111 is larger, the particle size of the ground food material powder or soybean powder is larger. On the contrary, the particle size after grinding is smaller.
