Abstract: A ballistic projectile arrester having a regeneration and/or recovery system for the impact material, and which is particularly suitable for the recovery of projectiles fired by small arms or the like in indoor firing ranges or shooting galleries is disclosed. The projectiles are fired into a quantity of granular material which is preferably fireproof and capable of dissipating the kinetic energy of projectiles in a safe way. The granular material is supported so as to provide a sloping surface having a maximum thickness at the point of penetration of the projectiles into the granular materials. The mixture of materials and projectiles is kept circulating in such a manner that the projectiles absorbed by the granular materials can be removed and the granular materials can be continuously recycled back into the separator to replenish the materials which have been removed from the impact area.
