Zato | Blue Devil shredding entire cars with engine 

Not no more!

lmao, good one!!!

Hammer shredder is faster

I just came

Nope, engines go straight through...np

Nope. Shredding allows the metals to be magnetically separated from the non-metal like plastics and rubber.

@@kansasthunderman1 For sure one can do better materials separation after shredding. But the shredding process needs huge amounts of energy and does have high maintenance costs. And where do the very mixed plastic and rubber fractions go to after? In the classic non shredding process these materials serve as an additional fuel source in the blast furnace. For one can not separate all foreign matter by shredding (for example the car paint), all up-to-date blast furnaces have by definition exhaust filters to cope with the potential toxic gasses created by the "polluted" steel source. These filters can easily take care of some extra pollution. I still wander about the added value.

@@tuttebelleke In the U.S., car shredding is done with "Hammermills" which use a combination of direct impact and another phenomenon called "interactive abrasion" to shred and "scrub" the metal of any deposits like paint and undercoating. Most hammermill shredders have a rotor which creates a turbulent vortex like a tornado where the metal swirls around and cuts rubber and plastics. The nonmetallic debris is removed by large vacuum cleaners and the steel and nonferrous metals are then removed by magnetic separation. The final output of a shredding plant is typically about 95% pure metal without any contamination and ready to go to the electric arc furnace. Hammermill shredders also have a very high production rate and a 6000 horsepower machine can process over 300 cars per hour. Despite the huge energy consumption, shredding plants produce steel and aluminum scrap at the lowest cost per ton than any other method of processing. In fact, all scrap metal processing techniques are engineered using cost-per-ton as the metric of performance and mathematical models of the shredding process have also been developed to predict how parameters such as rotor diameter and RPM affect the throughput of the machine. For more information about how these shredding plants work, do a search for "Scott Alton Newell" who is the son of the original inventor of the car shredder in the 1960s. Newell has written many technical papers on how the shredding process works.

@@kansasthunderman1 Thanks for your reply. I couldn't find a hammermill shredder where entire cars are fed in? So the hammermill shredder comes after the classic shredder, I suppose? If yes, one has to calculate the recycling costs with 2 shredders?

I believe it's driven by a hydrostatic transmission instead of a gear reduction.

Bullshit! Your foot would jammed that crushing Zato machinery 😊👍

but there was millions of cars less in the 1960`s that needed shredding / scrapping.. maybe the next 60 years time there will be no cars

I remember once in car the park stopped behind cars waiting for a car to back in and right window 3-4 feet next to a wood chipper going full rpm blast. And this idiot guy throw in a cut 1-1/2 foot x 1 foot stump. I was wtf. That gear is going to emplode right next to me. It kept chewing it round then both top and bottom open up 1 foot and it swallowed it without it shredding it. What a great good surprise. You never want to be that close to a steel gearing& high rpm doing 10,000 rpm and a big log ,something going to give.

So just watch one. Kind of mesmerizing watching a few cars go down the old porcelain convenience...

NO! That's MY CAR a CTS Sport!

You can see an engine bouncing around at 1:15 I think.

@@ottopartz1 You right, i am sorry

Except for the Volvo which has its engine...

These are a lot less maintenance than a hammer mill

Are you kidding. You think you know more than the engineers that built this thing?

The scissor action where the rotors come together is the magic.
