N2 - The processing of gun propellants can be carried out using the continuous shear roll milling process, which consists of two counterrotating and grooved rolls that are run at different speeds and temperatures and that exhibit different surface roughnesses. During the shear roll milling process, the water content of the propellant is decreased upon heat transfer with the rolls and upon the viscous energy dissipation generated, especially when the propellant is subjected to the shearing action at the nip regions between the two rolls. The propellant can also be granulated. In this process the propellant needs to stick to one roll and detach from the surface of the second roll. Here a mathematical model of the process is developed and is used to explain the experimental findings collected during the shear roll milling of a live gun propellant formulation.
