A ball shell cover 301 is fixedly installed at the opening at the upper end of the grinding ball shell 3. A water inlet pipe 301a and a water outlet pipe 301b are connected to the ball shell cover 301. The water inlet pipe 301a injects cooling water into the grinding ball shell 3, cooling the grinding ball shell 3 and preventing the high temperatures generated during grinding from oxidizing the tea leaves and causing the loss of aroma.
[0027] Specifically, the grinding bowl 2 is rotatably installed inside the outer support sleeve 1. The lower end of the outer support sleeve 1 is equipped with a drive motor 201.

At the same time, the heat generated by the grinding ball shell 3 when grinding the tea leaves is carried away to prevent high-temperature oxidation of the tea leaves and loss of aroma.
[0029] Furthermore, a set of ball bearing seats 101 are fixedly arranged in a circumferential array on the inner bottom surface of the outer support sleeve 1. A hemispherical ball groove 101a is opened on the upper end surface of the ball bearing seat 101. A ball bearing 101b is rolled and sleeved in the ball groove 101a. The lower end surface of the grinding bowl 2 is attached to the ball bearing 101b, so that the grinding bowl 2 and the ball bearing 101b roll and rub against each other.
[0030] Furthermore, a ball sleeve 101c is fixedly sleeved on the upper outer side of the ball seat 101, and the upper end face of the ball 101b penetrates the ball sleeve 101c.
[0031] The operation process in this embodiment is as follows:
[0032] The dried and coarsely chopped tea leaves are placed into the grinding bowl 2. The lifting component 4 lowers the grinding ball shell 3 into the grinding bowl 2. The drive motor 201 drives the grinding bowl 2 to rotate within the outer support sleeve 1, so that the grinding ball shell 3 can finely grind the tea leaves in the grinding bowl 2. Cooling water is injected into the water-proof cover 301c from the water inlet pipe 301a. Cooling water is also injected into the gap between the water-proof cover 301c and the grinding ball shell 3 from the water outlet pipe 301c-1 until the gap between the water-proof cover 301c and the grinding ball shell 3 is filled and discharged from the water outlet pipe 301b. At the same time, the heat generated by the grinding ball shell 3 during the grinding of the tea leaves is carried away to prevent high-temperature oxidation of the tea leaves and loss of aroma.
