On April 18, Wanbo New Materials Co., Ltd., a subsidiary of Bosai Group, officially launched its alumina red mud drying project, which involved an investment of approximately 20 million yuan. After the project became operational, Wanbo New Materials Co., Ltd. could reduce the moisture content of red mud from 28% to 4% through drying, achieving a daily production capacity of approximately 5,000 mt of dried red mud, 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. The red mud drying project adopts a suspended-state circulating drying system, with an overall process route combining drying and mixing. This system is 30-40% more energy-efficient compared to conventional drying systems. It consists of a feeding system, a drying system, a finished product collection system, a mixing system, and a hot air system. These systems operate in coordination, with each link closely integrated to ensure efficient and orderly production. The core technology was independently developed by Beijing CAS-Leading Environmental Protection Research Institute Co., Ltd.
