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.

Dependent claims

A ballistic projectile arrester, comprising:

granular material for absorbing the kinetric energy of projectiles;
supporting means for supporting a quantity of said granular material and said supporting means including at least one supporting surface in a sloped relationship with a horizontal plane defined as being essentially parallel to the path of the projectiles;
first driving means for placing said supporting means in motion such that the motion of said supporting means results in the movement of the quantity of granular material supported by said supporting means in a specific direction;
receiving means for receiving a mixture of granular material and projectiles departing from said supporting means;
second driving means for transporting the mixture received by said receiving means to a separation zone;
separating means found within the separation zone and providing the means for separating the components of the mixture of granular material and projectiles;
delivery means for delivering the granular material separated from the mixture back to the supporting means and thereby acting to replenish the granular material lost to the receiving means;
and collecting means for collecting the projectiles separated from the mixture.
