Abstract
Procedure for granulating black powder with different grain sizes, characterized in that a cone mill of a type known per se is used with a grinding mechanism consisting of a conical rotor, spiral teeth, and a conical stator with Opposite taper, spiral teeth, adjustable for continuous variation of the degree of fineness of grinding, with a signal to read the gap width adjusted in each case, the rotor and stator consisting, for safety reasons, of materials that do not give off bishops, the adjustable stator having a stopping system to prevent any possibility of contact with the rotor, and a safety clutch also being inserted to separate the rotor from the grinding mechanism of the propulsion motor in the event of overload by the action of foreign bodies, and the propulsion motor being arranged below the grinding mechanism in a a surround box ventilated from the outside and armored in a dust-tight manner.
