A device that effectively produce matcha powder is provided and includes: a stirred media mill grinding portion, having a grinding chamber inside, wherein a side of the stirred media mill grinding portion defines an outlet port; a pin bar, rotatably received in the grinding chamber, wherein an outer circumference of the pin bar defines an opening, communicated with the grinding chamber; an air classifier, connected to the outlet port through a first tube assembly and defining a first output port and a second output port; a storage portion, connected to the first output port; a collector portion, connected to the second output port through a second tube assembly; and a wind guider, wherein an air outlet of the wind guider is connected to the outlet port and an interior of the storage portion to create a negative pressure environment.

The mill apparatus comprises: a container to which a discharge pipe is connected; a mill mechanism that is arranged in the container and pulverizes powder; a gas feeding mechanism that has a function of feeding a gas into the container; and a wing mechanism for adjusting an amount of gas discharged from the discharge pipe. The wing mechanism has a plurality of wings arranged point-symmetrically with an axis. The amount of gas discharged from the discharge pipe is adjusted by changing a gap between two wings adjacent to each other of the plurality of wings.
