Precious Plastic - Build a PRO plastic shredder (part 3.5)

[@thymark]

As a manufacturer of shredders, I can say a nice job done. About the coupling. You can use 2 the same chain sprocket gears connected with duplex chain. Using taperlock system, you can find the right size very easy and its dirt cheap. The number of tooths on the gears need to be divisible by 2. For the spur gears. Knowing the bearing center distance to each other it is simple to make a table what gear combination for each gear modul can be used. That way there are many more possibilities and biger chance to find some online. . As the file is nearly 700mb, I don´t have time to download and go through, but if somebody want, i can write all the possible gear combination here, just let me know the distance between shafts ( center to center )

[@ainguyen7350]

hi sir, as you are a manufacturer of shredder, i have a question that which things invole productivity of the machine ( i mean the types of motor, the speed of the shredder shaft or the types of knife) if i have the input information that i want to shred 40kg of plastic per hour, how can i define the power of the motor? please help me

[@TechBuild]

We use the same method of coupling in our factory.

[@marshallcruz7979]

@Keegan Grant I really appreciate your reply. I found the site on google and I'm trying it out now. Looks like it's gonna take a while so I will get back to you later with my results.

[@OlivierCR]

17:02 Step #1 should be: Ensure that your shredder is unplugged before attempting to disassemble the hopper

[@Robinproof]

Or Step #1 make sure the safety is on or there is a lock on the round power switch

[@Robinproof]

unplugging a 3phase plug is way too hard ;)

[@Danirio96]

Step #0 never put your f***ing hand inside the hopper while the thing is plugged

[@robk5969]

im glad this is here, paused to write a similar comment. was gonna say make sure estop is pressed as well, the cord/plug can be out of sight, you never know if some idiot is around the corner plugging it back in / turning the switch back on estop is right in front of you, you will see if someone is mucking with it

Don't worry guys, i have a button " pause" on my browser just in case

[@phildodd9942]

Congratulations on your skilled design and assembly of this industrial grade machine that should last for many years with the correct maintenance ! Brilliant - keep up the excellent work - thank you !

[@artantme]

I just can't believe they didn't have to file everything after cutting so it fits. It's just a straight fit. amazing.

[@TheCharls8]

Thank you guys🤯 we appreciate all his time for teach us how to recycle plastic in an efficient way🙌

[@virsavp]

a real bread and butter winning technology provider.

[@handdancin]

this is a very good design. much improved from old versions. i personally like the idea of using a cycloidal reducer, or planetary reducer, instead of helical bevel (which i assume is what you are using) because they are more suited to run in reverse, and in the cycloidal case, they are very tolerant to shock loading.

[@samengsberg875]

Great explanation and visuals. I'm looking forward to building it! Maybe ease off on the stock banjo and harmonica music in between operations, some of us like hearing the machines work!

[@PlanetarySymbio]

[@ProlificInvention]

Very cool! One of my long term projects is an engine that runs on a variety of recycled plastics. A machine like yours would allow me to compact the fuel greatly and reduce the "fill up" of the reaction chamber and the associated downtime. Great video btw

[@dmithsmith5880]

Oh man !! Great stuff. I would be interested in what you are up to. I am converting a pellet stove to run on HDPE and PP.. I need a good shredder to feed my hot extrusion feed with nice consistent chips of plastic. What are you pyrolizing the plastic directly into a modified internal combustion engine ? Plastic is great isn't it 👍

[@emanuelmp-ce7440]

Congratulations my friend! Your videos are the best I've watched on KZbin. Thank you so much for sharing your knowledge, skills and creativity with everyone.

[@ZirraAdalisk]

The 4:10 lathe is exactly the same model that I used to work on. I didn't think they were anywhere else. It is ancient.

[@Tomasz_Piekarski]

I have almost built this wonderful device and when I was attaching the last screw to finish it, I have realised I don't have 3-phase current at home so I have to disassemble it now. ;-)

[@hansdegroot8549]

Very interesting video. Thanks for sharing. I think the shredder is quite a complicated machine to build. Better to leave it to professional machine makers. I was surprised by the low RPM which is needed. (before, or was the for the V3 machine), I heard 70 RPM, now only 25-30. I have to study the technical specifications. When I downloaded the starters' kit yesterday, I was looking for the financial side of it. I found the files but the files seemed to be (only) estimations. I could not find the company which was mentioned in it. Does it really exist? They had an estimation for about 5000€ for the machine, Is there a parts' list available with prices how much which part costs?

[@katefarber5637]

Hello, I am a student looking into building a shredder. Do you have a list of parts, tools, and skills that you used in this process as well as the total time of labor that went into it? Thank you so much this would be very helpful!!

[@lens4006]

Cool de voir un francais dans le programme

[@firewzerihun6860]

thank you for sharing your experience would you share us the exploded drawing of the shredder machine

[@sampyter]

I LOVE the precious plastic project. Thanks for your contribution for a more sustainable world and all the work you are putting in. Just some food for thought, don't you guys think that by creating these videos in which you are showing kind of "complex" manufacturing techniques and expensive tooling, in a way you are kind of reducing your real target audience to just a few? Think that not many people knows how to use a lathe or even have one. Is there a way you guys think that we could redesign the machine a bit so it can be a more diy project? Then perhaps more people can actually build one. Cheers!

[@hansdegroot8549]

For 99% of mere mortals is this machine far too complicated to build.

[@sanaru02]

This. I would love to get into plastic shredding, yet I have the difficult choice of buying an overpriced low end shredder online or going back to school for a two year degree in order to even have a chance at building this right.

[@hansdegroot8549]

@@sanaru02 I think the double shaft is the most difficult and crucial part of the whole machine. I was surprised by the fact that the measurements of the shredded plastic is determined by the type of sieve you mount under it. Already some years ago (I know the precious plastic KZbin channel and web-site only for 7 months) I saw all kind of (home-made?) double axis shredders for plastic (which were not open source) but I have no idea what they cost and what their capacity is.

[@sampyter]

To add on this, I think if you're gonna buy a shredder, but then you are not thinking of melting all those pieces back together, then you might be even polluting more even if all that plastic takes a considerable less ammount of space. Why? Well, if they ever spill, small pieces of plastics are far harder to pick up and have a worse environmental impact.

[@sampyter]

Again, I love the precious plastic project, but I don't think it will have a huge impact (considering how much plastic is thrown away every day) unless it finds out the recipe for scaling up. Why not building a proper recycling plant with a big twist in branding and social awareness? Have you mapped the space recycling plants are taking in the market currently? To give you an example, here where I live, there are tens of brands that sell water in bottles right? But there is one that said that for each bottle you buy, x percentage goes to provide water in third world country areas. And just like that, because people now want things to be meaningful, this water bottle brand is growing like crazy. Anyway, just an idea vomiting. I hope you don't mind. Cheers!

[@jeepjeeping1229]

thanks so much for this video, exactly what i was looking for :)

[@petergarcia8225]

Great start...for the better world. Great Innovative Design. Small and Mobile.

[@havoc158]

The best way I found to clean the machine after use was to use the air compressor and blow it through and the best way to unjam the plastic was to turn it backwards you can get a power switch to do this

[@hansdegroot8549]

Did you make this PRO version already? Can you share how much you paid for the parts and for the assembly (or how many hours you spend working on it yourself)?

[@havoc158]

@@hansdegroot8549 I made the previous version but the Pro looks a lot better

[@beansprouts113]

ALWAYS use safety goggles when working with a grinder, especially with a cut off disk. ESPECIALLY when you're making a video showing people how to make the machine as an example. Love what you do but throughout the years I've seen a real lack of basic precautions and its only a matter of time.

[@urrick33333]

would be cool to surface grind the blades also... i've made a small shredder and that was the main issue. you can never have too much precision.

[@urrick33333]

...and spacers!

[@danjones9999]

I really love what you are doing and I was super excited to be involved and start a plastic recycling centre where I am, hoping that I could build these machines in my workshop inexpensively. I have a thousand ideas for things to build with recycled plastic. Problem is, they are great machines and to build them properly costs thousands! It's all totally prohibitive unless you have a spare £20k kicking around, which I don't. I started to collect the parts to build a plastic extruder and realised that the motors are hard to find and really expensive and the original plan of using a cheap auger bit instead of an expensive extrusion screw just doesn't really work. Such a pity, but good on everyone who can afford to jump in and build these machines! Great project. If you could find a way of using readily available, affordable, recycled components to build these machines, then you would be on to a revolution! In the meantime, it's actually just easier to go on ebay and buy commercial equipment - it's cheaper and a whole lot simpler!

use a hand jack to "power" your extruder

That is quite a lot of torque. Are you sure the two square tubes in the frame are enough in the long run? That is the weakest spot, I think, and the frame might end up slightly crooked and weld cracks appear. Otherwise, super-impressive work!

I dont want to mess up the build right from the start so i really need some advice. Im afraid its a long shot getting some info here :( Also the flatbars where you cut 2 holes into each is nowhere in the starter kit
