I think the http://www.amazon.com/Northern-Industrial-Tools-Automatic-Crusher/dp/B0000AXDY9/ref=pd_sim_k_2 is a nice idea as are a lot of the ideas with pneumatics but this is over complicating a simple device. Just use a linear actuator to either operate the existing leaver of the can crusher os simply use the actuator to crush the can on any one of the feed mechanisms listed above.
