hi..
precisation: from gearmotor to shredder i have a 30:21 chain reduction…. so (i think) it is near 57rpm and 250Nm torque.
teorically….!
keep in mind i have a very aged motor… i suppose it have a very low efficiency.
now i’m only testing it…
I tried shredding a few bottle cap
It reduces them shattered very easily.
Now I…[Read more]

Hi all, people,
Unfortunately i can’t upload pictures (server sayd i can’t 🙁 )
However you can see pictures in my google album: https://goo.gl/photos/pwUaB9SaTPEce7V4A
I’m near the end… but not finished yet

Bye bye

Hello, unfortunately on the plate of the hoist is only written: 1400 rpm and 2 hp.
But turning it by hand I saw that the reduction ratio is 36 or 37 … so the final shaft should be about 40rpm. Maybe there are few … but to get started okay.

I’ve some problem uploading photos. .. pls wait 🙁

I finally found the way to power the shredder: I found an old hoist and I’ve eliminated everything I did not need. Still under construction. Look at the photos

To Jegor:
I do not know yet. But I think I would build a 25 / 30mm iron tubular frame. It should not be difficult. I have to find the gearmotor first … then build the frame … of the right size. As soon as I realize it, I will post some photos

To Trent:
I made it by laser cut (my friend have a very big machine)

It was very hard to grind the various pieces because the project needed 5mm and 6mm thicknesses … but my dimensions were thicker. They should have a thickness of 149mm … instead I had 153 !!! I have sanded well 3mm of steel! Twice!
