Abstract
A method for obtaining the explosive charge in dry granular form as well as a device suitable for implementing the method. The method includes: filtering the suspension, by passing same through a static filter in order to obtain a cake containing the granular explosive charge agglomerated by residual liquid; dewatering the cake by subjecting the cake to pressurized gas; splitting the dewatered cake and obtaining a fluidized bed of the desired explosive charge by exposing the dewatered cake to at least one stream of gas; at least one stream of gas being injected, under the dewatered cake to impinge said dewatered cake, according to two consecutive modes and the gas having a humidity height below that of the dewatered cake and a dew point temperature higher than the injection temperature thereof; and stopping at least one stream of gas and recovering the explosive charge in dry, granular form.
