1. Selecting High-Quality Raw Materials
High-purity aluminum hydroxide and pseudo-boehmite are typically used as the primary raw materials for producing activated alumina. The purity, impurity content, and crystal structure of these materials directly affect the specific surface area, pore volume, and adsorption performance of the final product.
Zibo Xiangrun Environmental Engineering Co., Ltd. follows strict raw material selection standards and conducts quality inspections on every batch of incoming materials, ensuring stable product performance from the source and providing a solid foundation for subsequent production processes.
2. Mixing and Forming
After the raw materials have passed inspection, they enter the mixing and forming stage. Based on the requirements of different industrial applications, the raw materials are scientifically proportioned and processed using advanced ball-forming and particle control technologies, resulting in products with uniform particle size, excellent sphericity, and high mechanical strength.
Zibo Xiangrun offers activated alumina in a variety of sizes, including 1–2 mm, 3–5 mm, 4–6 mm, 5–7 mm, and 6–8 mm, and also provides customized specifications according to customers' operating conditions to meet the requirements of compressed air drying, natural gas dehydration, water treatment, air separation units, and other applications.
3. Drying Process
Freshly formed activated alumina particles contain a certain amount of moisture and must undergo a carefully controlled drying process to remove internal moisture evenly, preventing cracks, deformation, or powdering during the subsequent calcination process.
Zibo Xiangrun adopts a scientifically controlled drying process to ensure a more stable particle structure, creating ideal conditions for developing a uniform pore structure and high mechanical strength.
4. High-Temperature Calcination
Calcination is the most critical step in the entire production process and plays a vital role in developing the adsorption performance of activated alumina.
By precisely controlling the calcination temperature, holding time, and heating and cooling rates, the raw materials gradually undergo dehydration and crystal phase transformation, forming a well-developed pore structure and a large specific surface area. This gives the finished product excellent adsorption capacity and regeneration performance.
5. Screening and Dust Removal
After calcination, the product undergoes multiple screening and dust removal processes to remove fine powder, broken particles, and off-spec materials, ensuring uniform particle size and a consistent appearance for every batch.
Zibo Xiangrun strictly screens every batch of products to ensure that customers receive activated alumina with stable and consistent quality.
6. Quality Inspection
Quality inspection is carried out throughout the entire production process. Before shipment, activated alumina is tested for multiple performance indicators, including specific surface area, bulk density, static water adsorption capacity, compressive strength, abrasion loss, particle size distribution, and moisture content.
Zibo Xiangrun has established a comprehensive quality management system and conducts rigorous inspections on every production batch to ensure that all products meet customers' technical requirements and provide reliable long-term performance.
7. Packaging and Storage
To prevent moisture absorption during transportation and storage, activated alumina is typically packed in jumbo bags and palletized with moisture-proof and contamination-resistant protection.
Zibo Xiangrun provides different packaging solutions according to customers' export and transportation requirements, ensuring that the products maintain excellent performance and appearance throughout the shipping process.
