[0013] Beneficial effects of the utility model:

[0014] The grinding, screening and mixing machines are integrated into one, which simplifies the structure and forms an integrated machine, eliminates the conveying equipment, simplifies the operation and saves costs. At the same time, it also pays attention to environmental protection and energy conservation, uses red mud as raw material, realizes the effective utilization of resources, reduces costs, and promotes environmental protection. It alleviates soil alkalinization and reduces environmental hazards by reducing the accumulation of red mud. The device is more energy-saving and convenient for production and manufacturing. It helps to reduce environmental protection costs and promote the sustainable development of the ecological environment by effectively utilizing red mud resources, while promoting the resource utilization of bulk industrial solid waste. It can process red mud efficiently and quickly, thereby quickly promoting the large-scale comprehensive utilization of red mud. At the same time, other materials are added according to the raw material ratio for stirring to make the materials fully and evenly mixed for subsequent processing, effectively realizing the resource utilization of red mud and reducing the harm to the surrounding environment caused by the red mud stacking process.
