The alumina red mud drying project of Wanbo New Materials Co., Ltd. was put into operation today, with an investment of approximately 20 million yuan. Through this project, the company can dry the red mud from 28% moisture content to 4%, achieving a daily production capacity of 5,000 mt, effectively addressing the issue of sludge stickiness. The dried red mud can be widely used in fields such as cementitious materials, brick making, metallurgy, and as a raw material for cement. This project adopts a suspended-state circulating drying system, with an overall process route of drying + mixing mode, achieving energy savings of 30-40%. The system consists of feeding, drying, finished product collection, mixing, and hot air systems, which operate in coordination to ensure orderly and efficient production. The core technology of the project was independently developed by Beijing CAS Leading Environmental Protection Research Institute Co., Ltd.
