ABSTRACT OF THE DISCLOSURE A can crusher is provided with a can feed hopper having an open inlet at the top of the can crusher through which opening a plurality of cans may be inserted one after another to fill the hopper. Sequentially, each can falls by gravity into a crushing compartment where a power-driven ram crushes the can axially to crumple the can's cylindrical wall thereby reducing the can's length to about one-fourth or less of its original length. The crushed can falls by gravity through a discharge chute to be automatically discharged. Each can in the hopper automatically falls in succession into the crushing compartment to be crushed and discharged. To prevent human fingers from being inserted through the hopper inlet or the discharge chute and into the crushing compartment, the guiding chute paths are non-linear and/or tortuous to reduce the length thereof and to block a straight finger insertion into the crushing compartment. To remove an uncrushed can from the crushing compartment, the can feed hopper may be detached; and this detachment operation automatically operates an electrical switch to disable a power drive for the ram to thereby prevent crushing of the human fingers removing the uncrushed can. The preferred can crusher can be mounted on a vertical wall or it can be seated on a counter or table support. The cans are fed into the top of the can crusher, and travel in A straight vertical fall through the can feed hopper, the crushing compartment and the discharge chute to discharge at a lower portion of a front wall of the can crusher housing.
