The third spiral blade 18 can control the amount of material conveyed into the grinding machine 21 to avoid the problem of insufficient grinding caused by excessive conveying.

[0026] It should be noted that the present utility model is a fine grinding device for instant oolong tea powder processing. When in use, when the tea leaves fall into the crushing box 3 through the feed inlet 2, the two groups of mutually meshing first spiral blades 5 cut and crush the tea leaves. Then, the tea leaves fall on the filter screen 6 to filter out the still larger pieces of tea leaves. The inclined filter screen 6 makes the tea leaves slide into the reflux cylinder 7 by themselves and are conveyed to the first guide plate 12 of the discharge chute 11 under the action of the second spiral blade 9, and then fall back into the crushing box 3. This process is repeated to break the tea leaves into small pieces for subsequent grinding. The crushed tea leaves fall into the second guide plate 14 through the filter screen 6 and then enter the cylinder 16 through the feed hopper 19. Under the transportation of the third spiral blade 18, the amount of tea leaves entering the grinder 21 can be controlled to avoid insufficient grinding caused by excessive single-time falling.
