Introduction Silica is an artificially synthesized amorphous silicon dioxide (SiO₂) powder, with chemical formula SiO₂·nH₂O. It is an important functional material, widely used in fields of rubber, coatings, pharmaceuticals, etc. The performance of silica is closely related to key parameters such as particle size distribution (PSD) and specific surface area (BET), making efficient classification technology critical for optimizing its industrial applications. Air classifier produced by Qingdao

Introduction As important strategic resources, rare earths are widely used in the field of high-tech due to their unique physical and chemical properties. The particle size distribution of rare earths powders directly affects their magnetic, catalytic and optical properties, and traditional classification technology is difficult to meet the needs of high purity and narrow distribution. As a professional air classifier manufacturer,

Silicon Carbide (SiC) is an inorganic non-metallic compound formed by covalent bonding between silicon and carbon. Due to its exceptional properties of high hardness, high temperature resistance, corrosion resistance, high thermal conductivity, and wide bandgap semiconductor, SiC has a wide application in multiple industries. Additionally, its powder processing technology also indirectly influences the performance of end products. Applications

Introduction Aluminum hydroxide (chemical formula Al (OH)₃) is an important inorganic compound. It is widely used in medicine, ceramics, lithium battery precursors, etc. In this article, we will discuss the application of aluminum hydroxide as a precursor of lithium battery positive electrode material. The application of aluminum hydroxide in the precursor of positive electrode materials

1. Introduction of coal gangue Coal gangue is a solid waste by-product generated during coal mining and washing. Its main components include silicon dioxide (SiO₂), aluminum oxide (Al₂O₃) and iron oxide (Fe₂O₃). Coal gangue has characteristics of low calorific value (usually < 12 MJ/kg), high sulfur content, and easy spontaneous combustion. Long-term storage of coal gangue
