They are pictures of the largest metal shredder in America. The machine is 500 feet long and four stories high. The primary service is 138 KV, 400 amp. It steps down to 4,160 V for the different parts. The major drive motor is 7,000 Hp It shreds whole automobiles, tires and all, at the rate of six a minute or 16,000 a week. The residue is sorted by blowers and electromagnets for salvage. It is the largest project that I have ever had the opportunity to inspect. They started the project last fall and it is now in operation.
Unfortunately the motor is not very impressive looking. It doesn't even look like a motor. It is enclosed in a box shaped housing about eight feet wide and high and about twelve feet long. It is about as fancy as looking at a walk in cooler. It is a 4,160 volt. Originally it was supposed to be an 8,000 Hp but,the company building it had a problem so they found the 7,000 Hp sitting on a shelf somewhere and substituted it. The neighbors are happy that the three story stack of junkers has been reduced to below the landscaped berm. Alan--
There is a facility similar to this one located off of Rt 91 in North Haven, CT (for anyone who is familiar with the area). It has a tiny 4000 HP motor by comparison.
The operartor of the shredder sits in a "bomb proof" control room because of the occasional propane tank that slips through, which does happen with such a high feed rate. (I am sure the facility pictured is no different.) I was told the shredder operator of the North Haven facility has been knocked on his keester a few times because of such mishaps.
