[0002] Desulfurized gypsum is a byproduct of wet desulfurization of industrial flue gas. my country is a major coal-fired power producer, and the amount of desulfurized gypsum emitted is enormous, accumulating in thermal power plants and posing a potentially serious environmental impact. In cement production, it is usually used as a retarder. Before using gypsum, it needs to be crushed, and different sizes of gypsum need to be screened.

[0003] The existing Chinese utility model patent with announcement number CN211051607U discloses a clean and efficient crushing and screening device for desulfurized gypsum production, including a batching silo and a quantitative feeder; the batching silo is an inverted pyramidal cavity; a screening mechanism is detachably connected below the discharge port of the batching silo; the screening mechanism includes a screen basket with open upper and lower ends; a screen plate is movably arranged inside the screen basket; a crushing mechanism is also arranged in the batching silo above the discharge port; the crushing mechanism includes a first rotating shaft and a second rotating shaft; a first crushing rod is arranged on the first rotating shaft; a second crushing rod is arranged on the second rotating shaft; when the first crushing rod or the second crushing rod rotates to the lower position, the first crushing rod or the second crushing rod contacts the upper surface of the screen plate; the technical solution adopted by this utility model solves the problem that the crushing efficiency of the crushing auger is low, and some small clumps of material remain on the screen plate after crushing, which are difficult to transfer and clean, and after a period of time, the screen plate accumulates and blocks, resulting in poor material discharge.

[0004] Based on the aforementioned patent searches and the findings of existing equipment, it was discovered that my country is a major coal-fired power producer with a huge amount of desulfurized gypsum emissions.
