the solution to this is a small hydraulic piston.you don't need all of the complicated gears, and the whole thing is more compact.

What I think would be most applicable would be a pneumatic piston. With enough space between the piston and the can, you could use a compact air cylinder to easily crush a can. Try looking around mcMaster and surplus center. Also a two way cylinder would be WAY more awesome.

The hydraulic system does seem a more efficient way to crush the can. I do not have enough experience with it to say with any authority. I do think, however, that automating the feed system will effectively negate the need for high speed crushing.
I have attached a quick sketch of my idea.
The system would be a fairly simple gravity fed hopper, of a type I have seen coupled with Arm-Strong can crushers. A hopper positioned above the crushing piston and would have the cans prearranged in a manner that would facilitate the crushing process.
A can would fall in place before the crushing piston and prevent any further cans from falling in. This is very very much like the ammunition feed system in a original Gatling Gun. The piston would begin to crush the can, pushing it out of the way of the waiting cans. The piston itself would prevent the cans from loading until the piston has returned. Again, much like the bolt in a Gatling Gun.
On the other end of the containment cylinder, a crushing bulkhead would provide the resistance necessary to crush the can. I understand this differs from Ben's design and would require that this bulkhead be firmly mounted to the super structure of the device.
Once the can comes in contact with a pressure sensor, the bomb-bay style doors would open allowing the crushed can to drop out once the piston begins to retract. This would need to be on some kind of delay to prevent jamming. Once the piston retracts, the crushed can can fall into the recycle bin.
The piston will then return to the original position, allowing the next can to drop into place.
I was thinking of the same thing, but you seem to formulate your idea more into a pratical design.
A hydraulic cylinder would work, but it would be overkill for just a can. I'm building one with a pneumatic cylinder that has a 5" long rod and has a 2" bore. Plus hydraulics you need a pump, reservoir, relief valve, and hydraulic oil. While pneumatics you only need the cylinder, air compressor, and a manual valve
