[0002] Phosphogypsum is an industrial byproduct of wet-process phosphoric acid production, and its main component is calcium sulfate dihydrate. Large stockpiles of phosphogypsum not only occupy land but can also pollute the environment. However, phosphogypsum contains essential elements for plant growth, such as sulfur and calcium, and after proper processing, it can be used as a high-quality soil conditioner for improving saline-alkali land and providing nutrients.
[0003] In the process of preparing phosphogypsum into a soil conditioner, it needs to be thoroughly and evenly mixed with other additives and water. Existing mixing equipment is usually single-function and has difficulty breaking up clumps of phosphogypsum, resulting in uneven mixing with other materials and affecting the effectiveness of the conditioner. Conventional paddle mixers have insufficient mixing capacity for powdered materials and require a long mixing time. Summary of the Invention
