PURPOSE: A system for breaking metallic can such as aluminum can or steel can used for food and beverage is provided to recycle and re-use the can by finely crushing and grinding the can. CONSTITUTION: The system is for separating breaking velocity and size of broken material in multi-stage breaking processes; and finely grinding impurities (such as steel beads) contained inner/outer portion of the can, thereby to increase breaking efficiency thereof. Additionally, by removing the steel beads and residual gas during an initial process, prohibited are a breakdown of blade in the breaking system and fire and/or explosion and reduced is a vibration of the system by physical separation of the multi-stage breaking processes.
