Abstract
An apparatus to allow manufacture of fine particle PETN (penetaerythritol tetranitrate) having a sensitivity to propagate in thin layers in slurry and having a particle size which presents advantages in safety of handling and ability to obtain higher solids loading in slurries and flexible explosive binder systems due to a lower surface area, and a wider particle size distribution, compared to previous PETN of similar sensitivity to propagation in thin layers, i.e., as the major explosive ingredient in flexible sheet explosive formulations, and to propagation as a high velocity detonation in small core loads, i.e., 1 grain/ft., in mild detonating fuse, confined detonating fuse, and the like.
