Abstract
According to this process, there is used a granulator (10) employing a rotary drum and a fluid bed which is usually employed for producing dense granules for the production of porous granules, For this purpose, the process comprises spraying in this granulator ammonium nitrate in solution and effecting a combined cycle of granulation and drying which causes the formation of pores in the mass of the granules. The drying is then terminated in a drier (20) and the product thereafter is screened and cooled.
