When the rough grinding mechanism 5 crushes and grinds the clay raw material, the reaction force of the clay block on the rough grinding roller 52 can be transmitted to the buffer sleeve 54 through the connecting frame 53, the buffer sleeve 54 transmits the impact to the shock-absorbing spring 553, and the shock-absorbing spring 553 absorbs it, realizing the elastic grinding of the rough grinding roller 52, protecting the rough grinding mechanism 5 and improving the stability of the device.

[0025] Refer to Figure 2 , specifically, the screening plate 51 is connected to the inner wall of the grinding box 1, a transfer track 511 is provided at the edge of the screening plate 51, rollers 521 are provided at both ends of the rough grinding roller 52, and the rollers 521 are connected to the transfer track 511 in a matching manner.

[0029] Working principle of the utility model: The clay raw material enters the coarse grinding chamber 4 through the feeding hopper 3 and falls onto the screening plate 51. The fine clay particles fall through the screening holes 512 and are gathered into the grinding cylinder 74 through the material gathering port 75. The large clay lumps are screened out by the screening plate 51. Driven by the power provided by the coarse grinding motor 56, the connecting shaft 55 rotates. Due to the cooperation between the slide rail 551 and the connecting groove 541, the connecting shaft 55 drives the buffer sleeve 54 to rotate, and the connecting frame 53 rotates synchronously, thereby driving the coarse grinding roller 52 to roll and crush the clay lumps screened out on the screening plate 51. During this process, the rollers 521 arranged at both ends of the coarse grinding roller 52 rotate along the transfer track 511 on the edge of the screening plate 51 to ensure the stable operation of the coarse grinding roller 52. When the coarse grinding mechanism 5 crushes and grinds the clay raw material, the reaction force of the clay lumps on the coarse grinding roller 52 can be transmitted to the buffer sleeve 54 through the connecting frame 53. The buffer sleeve 54 transmits the impact to the shock-absorbing spring 553, which is absorbed by the shock-absorbing spring 553, realizing the elastic grinding of the coarse grinding roller 52, protecting the coarse grinding mechanism 5, and improving the stability of the device. Synchronously, the fine grinding motor 71 drives the fine grinding shaft 72 to rotate rapidly, thereby driving the fine grinding roller 73 to rotate rapidly. The fine grinding roller 73 and the grinding cylinder 74 finely grind the small particle clay falling from the screening plate 51, thereby improving the grinding effect and the uniformity of the clay particles.
