[0015] Figure 1 is a structural schematic view of the tea powder automatic crushing device. DETAILED DESCRIPTION

[0016] The tea powder automatic crushing device will be further described below in combination with the drawings.

[0017] As shown in the drawings, Figure 1 A tea powder automatic crushing device includes a mechanical crusher 1, a cyclone separator 2, a dust collector 4, a first centrifugal fan 6 and a screw conveyor 8, wherein the discharge port of the mechanical crusher 1 is in communication with the upper end of the cyclone separator 2; the top of the cyclone separator 2 is in communication with the dust collector 4, and the bottom discharge port of the cyclone separator 2 is in communication with the screw conveyor 8; the upper end of the dust collector 4 is in communication with the first centrifugal fan 6, and the discharge port of the dust collector 4 is in communication with the screw conveyor 8.

[0018] After the tea leaves to be processed are crushed by the mechanical crusher 1, the negative pressure generated by the first centrifugal fan 6 causes the cyclone separator 2 and the dust collector 4 to be in a negative pressure state, and the material crushed by the mechanical crusher 1 will first enter the cyclone separator 2 for separation, the larger particles directly enter the screw conveyor 8 for subsequent processing, and the smaller particles enter the dust collector 4 for solid-gas separation, the separated material enters the screw conveyor 8 for subsequent processing, and the air without dust particles is discharged into the atmosphere under the action of the first centrifugal fan 6, thereby avoiding environmental pollution.

[0019] In this embodiment, in order to obtain better crushing effect, a hammer crusher 14 and a buffer bin 9 are further included, the discharge port of the hammer crusher 14 is communicated with the buffer bin 9, the buffer bin 9 is further communicated with a second centrifugal fan 12, and the discharge port of the buffer bin 9 is communicated with the feeding port of the mechanical crusher 1.
