The protective cover 14 is opened to facilitate feeding of the grinding device 2. The bottom of the protective cover 14 is fixedly connected with a plurality of grinding columns 15. When the grinding device 2 moves downward, the distance between the sieve plate 16 and the protective cover 14 is shortened, so that the barite is extruded and ground. The grinding columns 15 connected to the protective cover 14 can further grind the barite. In particular, when the amount of barite on the sieve plate 16 is less than the distance between the sieve plate 16 and the protective cover 14, the grinding columns 15 can still grind the barite on the sieve plate 16.

[0028] With reference to Figure 1 , Figure 2 , Figure 3 The driving device comprises a hydraulic cylinder 3, the output shaft of which is fixedly connected to the top of the protective cover 14.
