Activated Alumina 5-8MM Dryer Activated Alumina Activated Alumina is also called Activated Alumina.Silica gel desiccant,Mineral desiccant,Active desiccantIt is a kind of solid material with porous and high dispersity. It has a large specific surface area and good absorption.The adsorbent has good pressure resistance, wear resistance and heat resistance, so it is widely used as an efficient adsorbent and desiccant.And the catalyst carriers for various reactions.

According to the physical properties of alumina, alumina can be divided into three types: sandy, flour and intermediate. The physical properties of these three types of alumina are quite different. Sandy alumina has smaller bulk density, larger specific surface area, slightly smaller resting angle and less content.a-Al2O3Coarse grains are more uniform and have higher strength. Flour-like alumina has larger bulk density, smaller specific surface area and higher content.a-Al2O3There are many fine grains and poor strength. The physical properties of intermediate alumina are between them.
