1 Introduction
Porous ammonium nitrate is a valuable agrotechnical fertilizer. It is one of the components of the common explosive ANFO, widely used in the mining industry [1]. The
quantitative and qualitative indices of the porous structure of ammonium nitrate
granules (namely, porous ammonium nitrate PAN, according to [2–5] is the most
effective component of ANFO) have a decisive impact on the properties of common
explosive ANFO. The larger the number of pores, the greater the absorptivity of the
PAN granules toward diesel fuel. The balance between macropores and mesopores
affects the retentivity of PAN granules.
The multistage process of the ordinary ammonium nitrate granules humidification
with various humidifiers and the subsequent heat treatment stages in vortex granulator
is one of the most promising ways to obtain porous ammonium nitrate (PAN) as well
as multilayer granules [6, 7].
The pore structure of the finished PAN granules is effected by such indices as
the type of humidifier, the degree of granules humidification and the heat treatment
mode. In [8–10], the dependence of the qualitative and quantitative features of the
PAN granules porous structure on the type of humidifier is investigated. For laboratory tests, a laboratory a vortex granulator unit is used (Fig. 1). The batch of the
initial ammonium nitrate granules is heated to a predetermined temperature, then the
granules are moistened (humidifier—water) and subsequent heat treatment is carried
out (8 min at a temperature of a layer—108° C, thermodynamic parameters are taken
according to the results of studies [11, 12]). Samples of finished PAN granules are
studied using microscope. (scanning electron microscope eTescan Vega 3, formation
