Abstract
An improved process for the manufacture of water resistant dry blasting agents. Powdered, solid, water blocking agent and solid fuel, if required, is added as a suspension in a liquid non-hydrating fuel phase to porous ammonium nitrate prills. The process thus avoids unevenness of coating with water blocking agent of prior art processes and is particularly suited to on-site truck mounted manufacturing of water resistant blasting agents.
