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 )
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
I know im randomly asking but does someone know of a method to log back into an Instagram account..? I somehow forgot the login password. I would love any assistance you can give me
@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.
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
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 !
Congratulations my friend! Your videos are the best I've watched on UA-cam. Thank you so much for sharing your knowledge, skills and creativity with everyone.
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.
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!
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
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 👍
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. ;-)
Hebaaaat...tehnik...bukan bidang sy...tapi seneng liat cara kerja yg rapih...kenapa kalau kita tempat kerjanya jadi jorok ...berantakan ya...semoga orang tehnik kita belajar cara kerja yg rapih seperti ini.
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!!
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
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)?
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.
Hello, thank you very much for your contribution. I wanted to ask where I can find the files to cut the laser blades, I can't find them Greetings from Colombia thank you
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!
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.
@@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 UA-cam 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.
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.
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!
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?
I have bought all the parts in the BOM and am building the machine as we speak. Im stuck at the beginning as the frame 2d drawing is incomplete. Like the 80x40 where you´re drilling the cable management hole. Where does it sit exactly? what is the length of these 2 90 degree rotated 80x40? 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
Thanks for this amazing video. Can you please tell me how can I manage to make the blades if I don't have access to a laser cutter? In some areas of different countries with a lot of waste generated there is not access to this technology.
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!

Hello! Which version of Solidworks should i have in order to open the CAD files, because with my 2016 it can not? Or what program did you use and which year, to create all CAD files?
hi There , i have started to build this shredder and is going ok. But where can i buy the gears from in Australia, is there any one out there who can point me to where i can get them.
I never watched that type of video before but today i was at a fab-lab meeting and "precious plastic" was discussed during the round table discussion. I guess google's listening...
What kind of cold chop saw was that you are using? The green one at the beginning of the video. I used to work at a fabrication shop many moons ago that had the same saw.
@@thymark still not going to limit the toque input to the gearbox if the output of the gearbox stops you still have a massive rotor spinning around 1750 rpm which will break the gearbox. a torque limiting clutch between the motor and gearbox is a tried and true way with noon hydraulic setups.

@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.
17:02 Step #1 should be: Ensure that your shredder is unplugged before attempting to disassemble the hopper
Or Step #1 make sure the safety is on or there is a lock on the round power switch
unplugging a 3phase plug is way too hard ;)
Step #0 never put your f***ing hand inside the hopper while the thing is plugged
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

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 !
a real bread and butter winning technology provider.
I just can't believe they didn't have to file everything after cutting so it fits. It's just a straight fit. amazing.
Thank you guys🤯 we appreciate all his time for teach us how to recycle plastic in an efficient way🙌

Have you made a label removing machine for recycled plastic bottles? For home use?
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.
...and spacers!
