The outer-stator milling tools of each row in the circumferential direction each have the same length.

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.

An attrition mill that includes a grinding chamber having a plurality of grinding elements and an internal classification and separation stage. The mill also includes at least one grinding element providing a larger flow path therethrough, when compared to other of the grinding elements. In other embodiments, mill includes at least one grinding element having an open area in the grinding element created to allow a larger flow path as a proportion of the grinding element surface area without such allowance and in the range of from 15% to equal to or less than 100%.

An agitator ball mill comprises a grinding chamber (1), a rotatably mounted agitator shaft (5), which protrudes into the grinding chamber (1) and on which agitator elements (10, 20, 30), in the form of paddle wheels, are arranged spaced apart from one another axially, and an inlet (6) for supplying material to be ground and grinding bodies and an outlet (7) for removal of the ground material. The agitator elements (10, 20, 30) are constructed in such a way that, during operation, they convey a mixture consisting of material to be ground or dispersed and grinding bodies through their interior outwards away from the agitator shaft (5). In the grinding chamber (1) there are arranged return conveyor elements (17, 27, 37; 47; 57) which are joined to the agitator shaft (5) for conjoint rotation therewith and which convey the mixture laterally alongside and/or between the agitator elements (10, 20, 30) inwards towards the agitator shaft (5).

A agitating wet ball milling apparatus, by connecting one end of the second separation chamber in the length direction with the first separation chamber to form a second separation channel, increases the separation flow rate and reduces the pressure in the first separation chamber. During separation, the mass of the grinding balls is much greater than the diameter and mass of the material. When a small amount of grinding balls enter the first separation chamber, they move to the bottom of the first separation chamber under the action of gravity. The second separation chamber keeps the grinding balls away from the discharge port and also reduces the number of grinding balls in the first separation chamber that enter the second separation chamber for discharge. This ensures the separation flow rate while reducing the phenomenon of ball leakage and improving the grinding efficiency.
