High Alumina Ball
Activated Alumina has the advantages of large surface area, many mciro-pores, well disperser, so it has a high affinity for water/impurity and activated catalyst. According to the applications of balls, there are 3 types of Activated Alumina Sorbent, Activated Alumina Desiccant and Activated Alumina Catalyst carrier. Meantime interior composition of the crystal phase was divided into mode Y and X-P.

Overview of High Alumina Grinding Ball
Activated Alumina is an important type of ceramic packing material that has the advantages of large surface area, many micro-pores, well disperser, so it has a high affinity for water/impurity and actived catalyst. According to the applications of balls, there are 3 types of Activated Alumina Sorbent, Activated Alumina Desiccant and Activated Alumina Catalyst carrier. Meantime interior composition of the crystal phase was divided into mode Y and X-P.

KA401: is for as adsorbent
KA402: is for defluorinating
KA403: is for absorption in producing hydrogen perixide (H2O2)
KA404: is for catalyst carrier
KA405: is for dehydrating and drying in air seperation etc.
Application of High Alumina Ball
The activated balls are widely utilized in the drying agent of multiform gas and liquid, also function is used as sorbent, desiccant, catalyst support in reactors for petrochemical industry, chemical industry, fertilizer industry and so on.
