The gypsum powder in the flow channel 9 is guided into the collecting box 6, two sets of crushing rollers 16 are arranged in the middle of the base 1, a feeding hopper 15 is arranged in the middle of the top of the crushing bin 2, a conveying cylinder 4 and a guide groove 9 are respectively opened on both sides of the fixed bin 5, a filter plate 8 connected with the guide groove 9 is arranged on the top of one side of the conveying cylinder 4, a motor 3 is arranged at the bottom of the inner side of the conveying cylinder 4, a spiral conveying rod 10 matched with the conveying cylinder 4 is arranged at the output end of the motor 3, a return pipe 11 connected with the crushing bin 2 is arranged on the top of the conveying cylinder 4, and a dust removal component is arranged on one side of the top of the collecting box 6.

[0023] Furthermore, the dust removal assembly includes a vacuum cleaner 7, a dust removal pipe 12, a dust suction hopper 13, a filter screen 17, a filter box 18, a feed pipe 19 and an electric valve 20. A filter box 18 is provided on one side of the top of the collection box 6, and a vacuum cleaner 7 connected to the filter box 18 is provided on the other side of the top of the collection box 6. A dust suction hopper 13 is provided on one side of the bottom of the top plate 14, and a dust removal pipe 12 connected to the filter box 18 is provided on the top of the dust suction hopper 13. A filter screen 17 is provided on one side inside the filter box 18, and a door is provided at one end of the filter box 18 for convenient opening of the door to clean the filter screen 17. A feed pipe 19 connected to the collection box 6 is provided on one side of the bottom of the filter box 18, and an electric valve 20 is provided on the inner side of the feed pipe 19, which can absorb the dust generated when the gypsum is crushed and collect it in the collection box 6.

[0024] Furthermore, the dust hopper 13 is located directly above the feed hopper 15. When the dust generated by the crushing of the gypsum blocks floats out of the feed hopper 15, it can face the dust hopper 13, thereby preventing the dust from scattering outward and polluting the environment.

[0025] Furthermore, guide plates are provided on the tops of both sides of the crushing chamber 2 , and the guide plates can guide the gypsum blocks and the gypsum particles transported by the return pipe 11 .

[0026] Working principle: When processing plaster gypsum, the device can add gypsum blocks from the feed hopper 15, and then start two sets of crushing rollers 16 to crush the gypsum blocks. The crushed gypsum powder can enter the conveying cylinder 4 through the diversion of the diversion pipe. At this time, the motor 3 is started to run, and the motor 3 can drive the spiral conveying rod 10 to rotate, and then the spiral conveying rod 10 can convey the gypsum powder upward in the conveying cylinder 4. When the gypsum powder reaches the filter plate 8, the gypsum powder that meets the standards can pass through the filter plate 8 and flow into the diversion groove 9, and then enter the collection box 6 through the connecting pipe through the diversion of the diversion groove 9 for collection, while the gypsum particles that do not meet the standards can continue to be transported upward in the conveying cylinder 4. After reaching the top of the conveying cylinder 4, they can enter the return pipe 11, and enter the crushing bin 2 again through the diversion of the return pipe 11 for secondary crushing, so that the device can ensure the quality of the gypsum powder after crushing the gypsum blocks;

[0027] When the gypsum blocks are crushed, the vacuum cleaner 7 can be started to operate, and the crushed dust floating out of the feed hopper 15 can be sucked out through the dust hopper 13. After the gypsum dust passes through the guidance of the dust removal pipe 12, it can enter the filter box 18, and then the gypsum powder can be intercepted by the filter net 17. The airflow can be discharged through the vacuum cleaner 7. When a lot of gypsum dust is collected in the filter box 18, the electric valve 20 can be started to open the discharge pipe 19. At this time, the gypsum powder can fall into the collection box 6 through the guidance of the discharge pipe 19 for centralized collection, saving the waste of gypsum materials.
