Shanghai Jiuzhou offers spherical activated alumina in a wide range of conventional particle sizes, from 0.4mm to 8mm, to meet application requirements under various working conditions. So, how do you determine the most suitable particle size during actual selection?
The key lies in finding the optimal balance among adsorption efficiency, airflow resistance, and compressive strength:
Particle Size and Adsorption Kinetics: The smaller the particle size, the larger the specific surface area, and the shorter the path for gas or liquid molecules to reach the internal adsorption sites. Therefore, smaller particles typically offer faster adsorption rates, higher bed utilization, and enable more thorough deep drying.
Particle Size and Pressure Drop: Given the same adsorption tower size and constant airflow velocity, smaller particles result in smaller gaps between particles, leading to greater pressure drop (resistance) as air flows through. This can increase energy consumption for fans.
Particle Size and Mechanical Strength: Generally, larger particles exhibit higher single-particle crushing strength, better withstand the impact of high-velocity fluid flow and the pressure from upper material layers, and are less prone to pulverization and wear.
For most industrial dryers and adsorption equipment, JOOZEO 3-5mm activated alumina is the ideal choice that balances performance and stability. This particle size range achieves a good equilibrium between adsorption efficiency and mechanical strength—meeting drying requirements under conventional working conditions while ensuring reliable compressive resistance for long-term operation.
