Bauxite powder is made from bauxite ore through processes such as crushing, grinding and calcination. It has good refractoriness and chemical stability. As a ceramic raw material, it is used to make various refractory products and applied in the production of alumina, aluminum metal, etc., which are widely used in industrial production. With the development of intelligence and automation, the bauxite powder making process adopts advanced control systems and automated equipment. The process is energy-saving and environment-friendly, the production efficiency is continuously improved, and the finished powder is uniform and pure, meeting the needs of high-end markets.
The project was carefully designed and constructed by Zenith. After the project was put into production, its technical advantages were transformed into remarkable resource utilization results. Through the core process of independently developed grinding equipment, Zenith has promoted the utilization rate of bauxite tailings resources in the jurisdiction from the original 10% to over 90%, achieving an industrial upgrading from "low-efficiency rough processing" to "full-value deep processing". This breakthrough not only taps the potential of bauxite tailings resources, but also constructs a green processing industrial model with low input and high output.
Equipment: LM Vertical Mill
Material: Bauxite
Application: Refractory materials
Shanghai Zenith has fully leveraged its full industrial chain service advantages in the project's production capacity construction. The lean layout of the bauxite tailings grinding production line not only improves the utilization rate of production space but also ensures tight connection between processes, effectively reducing production time waste and achieving efficient collaboration throughout the entire process. In terms of environmental protection, the project integrates low-carbon concepts and is equipped with advanced dust removal equipment, providing dual technical and environmental protection guarantees for the stable production of 300,000 tons of high-value-added bauxite-based homogeneous materials per year. The implementation of this project has truly opened up a new path of sustainable development for enhancing the value of the refractory material industry chain.

Recycling Process Flow of Bauxite TailingsFor medium/low-grade high-alumina bauxite and crushed ore, appropriate amounts of high-grade raw materials are added to produce homogenized materials with predetermined composition. The blended raw materials are then fed into Zenith vertical roller mill for dry grinding, followed by homogenization in a blending silo. Finally, water or binders are added for mixing, and the mixture is shaped using hydraulic presses or rolling ball methods. This dry process features simplicity and low moisture content after forming. Compared with natural raw materials, the products exhibit stable mineral phases, uniform composition, and consistent density.
Comprehensive Tailings ManagementScientific treatment of bauxite tailings not only promotes circular economy development in the mining industry, creating new growth opportunities for mining enterprises, but also fundamentally mitigates environmental damage caused by tailings accumulation. As a key player in the grinding equipment manufacturing industry, Zenith adheres to the belief of green and sustainable development, continuously exploring and innovating in tailings treatment to achieve a win-win situation for environmental protection and economic benefits in the mining sector.
