[0029] The transmission assembly 32 is provided at the rear side of the equipment rack 1;

[0030] The coarse grinding assembly 33 is arranged above the filter box 311;

[0031] The driving assembly 34 is arranged on the left side of the top of the equipment frame 1. The transmission assembly 32 includes a transmission plate 321 installed on the rear side of the equipment frame 1. The top of the transmission plate 321 is rotatably connected to the transmission rod 322. A fixed block is installed on the rear side of the coarse grinding box 331. The transmission rod 322 rotates inside the fixed block. The surface of the transmission rod 322 is fixedly connected to a transmission wheel 323. The transmission wheel 323 is an eccentric wheel. The top of the transmission rod 322 is fixedly connected to a transmission bevel gear 324. The coarse grinding assembly 33 includes a coarse grinding box 331 installed on the top of the filter box 311. The bottom of the coarse grinding box 331 is fixedly connected to the top of the filter box 311 through a conduit. The coarse grinding box 331 The surface is fixedly connected to the inner side of the equipment frame 1, and the internal rotation of the coarse grinding box 331 is connected to a symmetrical coarse grinding roller 332. One end of the coarse grinding roller 332 is fixedly connected to a rotating bevel gear 333. The surface of the rotating bevel gear 333 meshes with the surface of the transmission bevel gear 324. The surface of the coarse grinding roller 332 is provided with a linkage component 4, which includes a linkage gear 41 installed on the surface of the left coarse grinding roller 332 and a rotating gear 42 installed on the surface of the right coarse grinding roller 332. The surface of the rotating gear 42 meshes with the surface of the linkage gear 41. The driving component 34 includes a driving motor 341 installed on the left side of the top of the equipment frame 1. The driving motor 34 1 is a three-phase asynchronous motor and is connected to an external circuit through an electric wire. One end of the output shaft of the driving motor 341 is fixedly connected to the driving wheel 342 through a coupling. The surface of the driving wheel 342 is connected to the rotating wheel 343 through a transmission belt. The other end of the left coarse grinding roller 332 is fixedly connected to the inside of the rotating wheel 343. A feed bin 5 is installed on the top of the coarse grinding box 331. By providing a filter assembly 31, the filter frame 312 is driven by the driving motor 341 and the elastic influence of the return spring 315, so that the filter frame 312 slides back and forth inside the filter box 311 to achieve a shaking operation, and the coarsely ground material is filtered and screened through the filter frame 312. , filter and collect materials that do not meet the size standards, facilitate subsequent secondary coarse grinding operations, and introduce composite standard materials into the fine grinding device 2 through the connecting pipe for fine grinding operations, so as to achieve rapid preparation of ultrafine materials. By providing a coarse grinding component 33, the material is driven by the drive motor 341 to perform preliminary coarse grinding operations, and the larger materials are ground and crushed, so that subsequent fine grinding operations can be better carried out, and rapid preparation of ultrafine materials can be achieved. By configuring a set of drive motors 341, costs are saved. At the same time, the contents not described in detail in this specification belong to the existing technology well known to those skilled in the art.

[0032] During operation, the material to be ground is first put into the coarse grinding box 331 through the feed bin 5. At this time, the driving motor 341 is started to drive the driving wheel 342, the rotating wheel 343 and the coarse grinding roller 332 on the left to rotate. When the coarse grinding roller 332 on the left rotates, it will drive the linkage gear 41 and the rotating bevel gear 333 to rotate synchronously. The rotation of the linkage gear 41 makes the rotating gear 42 rotate synchronously in the opposite direction. The rotation of the rotating gear 42 makes the coarse grinding roller 332 on the right rotate synchronously. In this way, the two sets of coarse grinding rollers 332 perform a preliminary grinding operation on the material. The coarsely ground material enters the filter box 311 through the conduit and falls into the interior of the filter frame 312. At this time, the rotation of the rotating bevel gear 333 drives the transmission bevel gear 324, the transmission rod 322 and the transmission wheel 3 23 rotates synchronously, and the rotation of the transmission wheel 323 causes the connecting plate 314 and the connecting rod 313 to slide forward, thereby compressing the return spring 315. The sliding of the connecting rod 313 drives the filter frame 312 to slide, causing the filter frame 312 to slide inside the filter box 311. With the continuous rotation of the transmission wheel 323 and the influence of the elasticity of the return spring 315, the filter frame 312 slides back and forth inside the filter box 311, and the coarsely ground material is filtered through the filter frame 312, so that the composite size standard material falls through the filter hole and the connecting pipe into the fine grinding device 2 for subsequent fine grinding operation, while the unqualified material will slide out through the dropout port opened on the rear side of the filter box 311 and be collected by the external collection frame for secondary coarse grinding.
