Ahh yess! Horsepower! There is one facility like that here in Hamilton at the foot of Parkdale Ave that I was in, and its pretty impressive to see when its running... Motor is only 6000 HP 4160V and only draws about 150A when its running, roughly 600A for a few seconds when they drop in a honda or similar, but a full 1200A when they drop in a handful of tired old North American automobiles... It was quite interesting to just be in the motor room/ change house whan the mill was running as the whole building shook... I have heard stories as well as Peter said the operator sits in a bombproof control room... There have been incidents where a stray propane cylinder or gasoline vapour has been present in such quantity to explode and completely clear everything out of the shredder and off one section of conveyor line!

For a size comparison, I posted some unique technical pics / info in April 2005 of USS BB-43 'Tennessee', of Pearl Harbor fame- see Iwire's link kindly added below- thanks Bob. The motor pics are of a rotor and stator during construction in 1920-22[?] 4 off x 3270v ; coincidentally 7000hp each.
Alan N, that will be some shelf too!

At least those look like Motors instead of big boxes. Alan--

I was at an machine vision presentation and happened to be talking with the engineer from a scrap yard. He was interested in improving the ability to sort coins that they were currently retrieving from automobiles that were then ground into tiny pieces. I had to remove my foot from my mouth when I laughed at trying to even justify doing such things.
He told me they are pulling about $80,000 per year in loose change from the cars they shred. He wanted to improve the ability to sort out coins from stamped metal slugs that were caught in various parts of the frame.
I recall the shredder this guy ran was running something like 15-20 cars per hour.
This thing sounds like it's got more bite...
7000HP. That's just silly. I'd like to see the motor starter on that baby.
There's money in the trash....

http://kd4dcy.net/tmi/pri.html Here it talks about 9000hp pumps for the primary reactor loop at Three Mile Island unit #2 (the melted one). And it also says there are four pumps per reactor, two primary and two backup, times two reactors - that's eight total on the island. These pumps can move 136,000 GPM - that's right, gallons per minute at a pressure of over 2000psi. They keep the water under that pressure to keep it form boiling. Of course only four of them are still usable! This is one of the most detailed engineering reports of what happened in 1979 I have read. [This message has been edited by Gus99 (edited 05-15-2006).]

I saw this shredder on Modern Marvels last week, I think it is still on the air.
BTW, GE has a 50,000hp motor, they use it to suck air out of a huge building to test aircraft engines.
