Rotochopper Shredder vs. Tires Showdown

[@clydeacor1911]

At our yard we take the rims off first, you're losing 100% of your aluminum and just from looking at your steel pile and all of the steel wheels you put in I'd say that you're losing 90% of your clean prepared steel. We separate the tires from the wheels by using either a mini excavator with a thumb or a big 320 excavator with a thumb, it peels the tires right off and can easily do close to 1,000 per day. As strong as the cables are in the tires those rims are sucking a lot of power and slowing your shredding production down quite a bit.

[@mariofilippi3539]

You are correct that tires stored outside are breeding grounds for mosquitoes. I used to work for my county's Mosquito Control Commission and sprayed lots of tire dumps. Plus they're an eyesore. Your shredding is doing a lot of good so thank you.

[@paulciampa]

You can increase your metal yield by lowering the magnet closer to the discharge conveyor and running the spoils a second pass....it is a learning curve for sure.

You may want to shred tires on a rainy day. Just a little water will make the tires easier to eat. The rubber has less traction on the rotor blades. I used to work at a Goodyear store. We had to cut the junk tires. We would use a little water on the cutter blades to make it easier.

[@HarrisPropertyMaintenance]

In the computer you can set where every 5 minutes or so it’ll run the rotors backwards for 30 seconds automatically. Whenever you’re running material really stringy like the steel cords in tires it really helps to run the rotors backwards for a extended period every so often to unwrap the cords and free up material that is just robbing power and productivity.

[@steveswartout7408]

I was thinking that it had the wrong blades for that job I've seen other shredders turn tires into 1 x 1 pieces

Landfill i used to frequent a lot had us all dump in a transfer station on site on week days and shredded everything going up to the landfill first. I think they had a big non mobile shredder and a sort line first for recyclables. This was 15 years ago though on the other side of the country from you ...

So I've worked on these machines before on the engine side. From several different brands in fact. For that matter I'm pretty sure I've met the Rotochopper salesman that was out during start up of this machine a few times before. But in regards to the torque output of these machines. I was working on a Lindner brand machine once, with a CAT C-18, and I asked their service manager what the torque output was on their gear box. I was told that for the machine I was on, which is about twice the size of the 75 dk, it was somewhere around 350,000 lb ft if I can recall. I also love your attitude of trying to think far ahead instead of being reactionary.

Those cutters seem to have a large surface area to them for brute force for general material. I believe you can change them out to have a smaller surface area for a more tailored knife like shear cutting which would slice through rubber better and make smaller pieces. Understand this is just a demo unit but they can be tailored more to a specific product.

[@TheRealMrDiGG]

Think you’re right

[@jt9498]

You're exactly right. The cutters that are in there now are way too big for what he's trying to shred. And another thing....they're overloading the hopper with too many tires at once. Those cutters aren't designed to shred (into small pieces).

[@flanjo.NZ.]

For years used tires have been a big 'PITA', these machines have solved that problem to a degree. Start-up looked simple, initially l thought you may have to employ a rocket scientist. As for the alloy rims you may need to set up a tire machine nearby and remove them to be recycled, but you already know that. Interesting video, keep up the good work.

[@GARDENER42]

Is it not worth separating out the tyres with aluminium rims & cutting the tyres off for the rims' scrap value?

Here in Australia we use these shredders to shred mattresses, cushions, couches etc and the product is called flok, which the landfill will then use on the turn pad when it taints to soak of moisture and allows trucks to move without getting stuck, then just take a skim off when the places dries up and you are good to go, plus as one landfill operator to another, mattresses suck ASS to pack!

if you added a screener to the mix I bet you could get it to shake out the aluminum rim chunks. those tire shreds have value too if they are clean I think somewhere around 200$ a ton it would probably take a another pass through smaller grinder to really separate the belts from the rubber though

I'll weigh in with some calculations on size reduction. A 16-inch auto tire is approximately 32" in diameter x 8" thick. (3.72 cu ft.) Of course because they're round they won't fit perfectly tight against each other in the roll-off. A 32" square that is 8" thick is 4.74 cu ft. I averaged them together to get 4.23 cu ft. A 20 yard dumpster is 540 cu ft. I'm guessing that approximately 128 tires would fit in a 20-yard dumpster. *Should have had Aaron count how many tires that monster had for lunch, when the bin was finally full! Awesome machine!

[@OfficeMackerel]

For aluminium recovery, you might want to run the ground up rubber and alu rims through an eddy current separator, then you'll get a saleable alu product at the end. Only problem is a fire risk from still-present ferrous wires in tire fragments heating up as they pass through the eddy current separator due to rapidly alternating magnetic fields. Could be something to investigate though?

[@TheRealMrDiGG]

That’s a very cool idea!

The total surface area of tyre chips or crumb particles may also be large compared with the volume occupied. The combination of permeability to air-flow and a high exposed surface area means that that a combustible material such as rubber is potentially susceptible to spontaneous combustion.

They were disappointed with it's initial performance. The tires would just bounce around in the grinder. Then water truck come by and wet the area down. Some water sprayed into the tub, and wow the tires started going down. You might find faster production with a little water on your pile. Good luck!

I think, with an aluminum rim tire setup, cut with jaws-of-life-type scissors, rubber falls off, and the aluminum rim easily separates thus, a quick aluminum pile, that sells for more than average.

Doing the aluminum wheels separately will pay off much more than you would think. Old school aluminum 15 inch wheels are good for about $20 each. I have never seen that type of cutters.
