[0002] The heavy calcium carbonate powder sorting system is usually used to separate and classify calcium carbonate powder according to particle size or density. Such a system generally includes the following key components and steps: Feeding system: introducing the original calcium carbonate powder into the sorting system through a conveyor belt or other feeding devices. Dust collection system: collecting the separated powder during the sorting process and controlling the dust emission in the system. Tailings treatment: treating the tailings after sorting, usually by re-screening or other treatment methods to reuse or safely dispose of them. The design and operation of such a system generally depend on specific application requirements and treatment objectives, and can be adjusted and optimized according to different powder characteristics and required sorting accuracies.
[0003] In the prior art, some powder sorters use multiple layers of sieves for screening. During the screening process, the powder on the top layer flies around, resulting in a deterioration of the overall working environment. During the sorting process of some powder sorters, it is impossible to avoid the caking problem caused by static electricity or moisture, so that the powder aggregates into small pieces and cannot be screened, and it still needs to be redispersed and then screened, which is very inconvenient.

A sorting door 14 is rotatably connected to the right side of the sorting bin 2. A door body 15 is rotatably connected to the front of the coarse material bin 3. A feeding platform 4 is fixedly connected to the upper side of the feeding bin 1. A feeding port 5 is opened on the upper side of the feeding bin 1. A motor 6 is fixedly connected to the rear of the feeding bin 1. An output end of the motor 6 is fixedly connected to a feeding rod 7. The feeding rod 7 is located inside the feeding bin 1 and is rotatably connected to the feeding bin 1. A rotating shaft 8 is fixedly connected to the front of the feeding rod 7. A connecting rod 81 is arranged in the middle of the rotating shaft 8. Scrapers 82 are fixedly connected to the four sides of the connecting rod 81. The scrapers 82 are located inside a sorting mesh 9 and are in close contact with the inner wall of the sorting mesh 9. The scrapers 82 are rotatably connected to the sorting mesh 9. A first fixing groove 10 is fixedly connected to the rear inside of the sorting bin 2. A second fixing groove 11 is fixedly connected to the front inside of the sorting bin 2. The rear of the sorting mesh 9 is in close contact with the inner wall of the first fixing groove 10. The front of the sorting mesh 9 is in close contact with the inner wall of the second fixing groove 11. A front fixing ring 83 is fixedly connected to the front inside of the scraper 82. A rear fixing ring 84 is fixedly connected to the rear end of the scraper 82. The sorting mesh 9 is arranged inside the sorting bin 2. A fixing frame 91 is fixedly connected to the front of the sorting mesh 9. Openings 92 are opened on the upper and lower sides of the fixing frame 91.
