25.1 Introduction
Ammonium nitrate with advanced porous surface, so-called porous ammonium
nitrate (PAN), is a necessary component of simplest industrial explosives. A
promising method of PAN producing is combination of heat treatment method and
hydration of granules in small vortex granulators [1, 2].
Hydrodynamic conditions of continuous and dispersed phases motion in the
vortex granulator workspace were described in detail in [3, 4], while the model
of moisture removal process from the granule to form a porous surface layer was
described in studies [5, 6].
Estimation of granulated porous ammonium nitrate (PAN) quality, which is
generated for mining industry, is carried out by the following factors [7–10]:
1. Absorptivity – amount of diesel fuel distillate (in percentage terms from granule’s total weight), which is absorbed by PAN after humidification with the diesel
fuel distillate
