    摘要: A process for the production of explosives grade ammonium nitrate prill (EGAN) comprises the steps of

    (A). producing seed ammonium nitrate prill as substantially monosized prills; and then
    (B). fattening using melt/solution of ammonium or mixed nitrates, with drying and thermal treatments, the seed prill in an inclined rotating jacketed pan granulator or a cascade of such pans to produce a final fattened EGAN prill product preferably having at most about 4 mm diameter.

    摘要: Explosive grade ammonium nitrate (EGAN) prills are made by a process that comprises the steps of:

    a. continuously spraying a 95 to 98% by weight solution/melt of ammonium nitrate (or a mixture of ammonium nitrate and minor proportions of one or more other EGAN - acceptable nitrates) in/with water under spray-head conditions causing the emergent jets to break into cascades of substantially mono-sized droplets;
    b. allowing the formed droplets to fall within a vertical duct;
    c. continuously feeding a stream of cooling gas upwards through the duct to effect cooling and solidification of the falling droplets and some removal of moisture so as to form substantially mono-sized EGAN prills of up to about 4 mm diameter, and
    d. continuously withdrawing the EGAN prills collecting at the base of the duct (such EGAN prills then optionally being further cooled and/or dried in a forced draught regime),
       the process being further characterised by intensification of the upward gas flow regime in the duct such that:

    (i) the temperature difference of the gas flow between its inlet to the duct and its outlet from the duct is at least about 60°C; and
    (ii) the falling velocity of the prills in the duct is at most about 3 metres/second relative to ground (i.e. a stationary observer external to the duct) the upward gas flow velocity being e.g. 6 m/s relative to ground for 2 mm prill and 9 m/s for 3 mm prill and, optionally,
    (iii) recycling the gas stream after washing and cooling and addition of any required make-up gas.
