Ammunition has a service life, and after the ammunition reaches a certain storage life, the ammunition can be retired due to the fact that the quality and the performance of the ammunition are reduced, and tactical technical indexes do not meet the requirements any more. For retired ammunition, the propellant powder and explosive are required to be treated in a direct destruction or reuse mode.

For small and medium caliber shells, a fixed setting mode is generally adopted, namely, a projectile and a shooting cartridge are normally combined together, the projectile is loaded into the shooting cartridge, and the opening of the cartridge is closed to clamp the projectile. To remove the propellant charge from the propellant canister for a loaded projectile, the projectile is first pulled out of the mouth of the canister. The cartridge case oral area has certain binding off clamp force, only needs certain pulling out elasticity can separate the pellet. At present, the shell is decomposed on a shell decomposing machine, a bullet and a cartridge case are respectively clamped by a clamping device, and the clamping device is driven by hydraulic pressure or air pressure serving as power, so that the bullet and the cartridge case are separated.

Six parallel hinge connecting rod structures are uniformly arranged on the inner wall of the sleeve in a circle. When the projectile is inserted into the sleeve rightwards, the six projectile clamping plates are pushed rightwards, and the springs are compressed, so that the projectile clamping plates tightly press the projectile.
