That looks downright medieval. Like some horrific torture device.
Sorry, my mind goes to dark places sometimes.
:-)
That certainly made to tear something up ! Gives me the creeps.
presume it's some form of shredder - for fibrous materials - too coarse for carding
Looks to be exactly what I need for a plastic shredder I need to build someday so I can prepare to melt down over 200 lbs of drink bottles
I like the high tech weight system! Is the guy at :07 only wearing socks?
The teeth are not fixed to the shaft must be for rippping cardboard or plastic ( or fingers).

They will be made into individual circular blades...
Not sure how that would be accomplished since the tooth pitch is wound around the drum as a spiral helix from a continuous ribbonQuote:

Here's the full set of 22 GIFs, in the order that I found them, including the two above. The first one will autoplay. Click the others to play.

Is that felt?
We used rolls like that at a company I used to work for. The company I worked for made the molded acoustic panels that go inside the trunk of a car.
Raw fiber is dumped into a hopper (like thick cotton candy) and then goes through a series of rolls with varying amounts of pressure and through rolls like this to process the material before it goes into a massive loom. Those teeth will cut you to shreds. It's very similar to razor wire. They have to be replaced whenever they show excessive wear or get a lot of build up (think melted plastic). They are wound onto the rolls with a lot of tension and fastened into place as one continuous thread. The rolls we used were well over ten foot long (or wide, depending on how you look at it).
If you want to see a mess, let something go through there (like a lost wrench or someone's keys) and break that wire while the machine is running. It goes everywhere and is a terrible chore to remove, not to mention the obvious cut hazard.
Nice welding job on #6 .
Now you wouldn't be going to make pyrolized plastic, diesel would you?Quote:

200#s of plastic bottles would pay to take them to a state that gives you nickel for a bottle return.
