Building The Precious Plastic Shredder 

Thanks bro! Yeah same, i should see if i can get some more infos of where plastic waste in germany goes and what the percentage is :)

Thanks mate! Really appreciate your input. Already working on the extruder machine, the first test on sunday was successful 😃 Thanks for your support!

@@ARTVENTUREFILMS Subscribed with the bell on!

@@vexirrational5045 you legend! Thanks heaps!😃

Thanks a lot 😃👍

Sorry for the late reply! The motor and gearbox is alright for a shredder but not strong enough for extrusion. If i remember correctly this is what i got: The motor I'm using has 2.2kW, 230V and around 75rpm output speed, 35:1 might be the gear box but not sure about that.

Thanks man! I was looking on the official precious plastic website for the amount of torque and rpms i need. You can find details to every machine and version on the page. That's how i knew which gearbox to get with the coupling. and when you know the torque of your gearbox, you can find the right coupling for it. I got the coupling from maedler. Just send them an email and they can help you out. The exact coupling i got from them was: 2x 60520502 - Kupplungsnabe RNT Größe 48 Ausführung AS für Taper-Spannbuchse 1615 1x 60509848 - Zahnkranz standard 98 Shore A rot Baugröße 48 Außendurchmesser 105mm 2x Taper-Spannbuchse 1615 Bohrung 40mm (Die Bohrung muss natürlich zu deiner Welle passen) LG :)

That's true, but mine would only help people living in Germany or Hamburg.

Hey thank you so much ! Yes i know, that was close. I wouldn't dare to go anywhere near this thing :) I will build in some security upgrades soon. Thanks for mentioning though. I bought the motor from a local electric motor shop with the gearbox included. I couldn't find many secondhand and i got some good advice on what would fit my needs. It's not super quiet but the most noise is coming from the crushing of the plastic anyways. It's a 2.2kw motor and it so far it's been crushing everything. It only struggled when feeding in too much plastic so that it had many layers of plastic to chew at once, if that makes sense. Might post an update video on how it performs if you're keen :)

Hey vielen Dank😃 war sehr schwer zum Teil aber jetzt wo er fertig ist bereue ich es keinesfalls!

@@ARTVENTUREFILMS Das glaube ich dir, gut das du so Hilfreiche Freunde hast!

@@clypeum5063 Auuu jaa! Ohne die wäre es schwierig geworden !

Hey Marvin, sorry für die späte Antwort. Ehrlich gesagt kam die Idee von meinem Mitbewohner. Wir haben nach einer günstigen Alternative zum Frequenzumrichter gesucht und dann das Ding gebaut. Wenn du Geld hast, dann würde ich dir empfehlen einen solchen VFD oder Frequenzumrichter zu kaufen. Die Dinger sind der Hammer! Hätte mir so viele Probleme erspart. Aber egal. Wenn du ein kleines Budget hast, dann schreib mir nochmal, vielleicht finden wir ne Lösung. Ich brauche nämlich diese Elektrobox nicht mehr.

Thankyou !!😃

Hey sorry for the late reply, you can see it in the video. I stopped the timelapse to show exactly where I put how many extra spacers. You might have to watch it in slower speed but you should be able to see it.

Thanks mate! Sure, the motor has 1450rpm and the gearbox output is 35rpm.

If you need any more details, just shoot me a message

I don't really know. But you can look up all the specs on the precious plastic homepage. They have the blueprints for all the machines and what torque is needed.

Yeah but I like how they make it look easy though. A crucial part to get more people involved i guess.

@@ARTVENTUREFILMS Well, I got her built and it works. I used a 1.5KW 240VAC motor driving a 20/1 worm drive gearbox all mounted on an old Rover Chip and Shred frame. I put a reversing switch on the motor and it works pretty well as long as you don't try and jam the chute full of milk bottles. Working on the melting arrangements now. Using a C Rex 100 PID driving five heater cuffs around a bit of water pipe. Melted HDPE will then be squeezed into a 150 mil long, 75 mil ID hydraulic pipe with a polished bore. Technically it should work but it probably won't on the first try. But if it don't, I'll try something else.

@@ARTVENTUREFILMS Could you please tell me how much tour per minute do the axis of your shreeder? the axis is the hexagonal barbell that rings and blades are fixed to it.

Thank you for asking! I'm working on an update video for the shredder and my process:)

What do you mean by hardbox? The shredder blades, shaft and the box, is that what you mean? I had to re-assemble it so often because you have to make it run smooth. You don't want any gaps and if it's too tight, it won't turn easy anymore.

😃 thanks!

depends if you buy everything secondhand or brand new. but between 500 and 1000 probably.

no i don't, i got it from a local dealer. You can find the specs on motor and gearbox on the technical sheet from precious plastic

Yeah man, where exactly? :)

around 1500 i think. but i bought a brand new motor. Right now i'm working on a new machine with more power. The bigger 4kw motor only cost 35€. the shredder kit already assembled was like 300 from the precious plastic bazar and the coupling 150.

@@ARTVENTUREFILMS500 euros for a shredder, not bad

@@davidgruty but then you also need a variable-frequency drive to power the motor. that one is another 500. forgot about that one

@@ARTVENTUREFILMSok... then shredder for 1000 euros. Not bad but also not good ;)

haha yeah, a lot of money @@davidgruty

Hahaha 😂😂 Gebe ich dir vollkommen recht! In Zukunft habe ich aber einen richtigen pusher ;)

Good point, I will watch out next time. Thanks for your thoughts!

Moin! Klar kann ich helfen, ich habe dünnes verzinktes Blech aus dem Baumarkt genommen. Die größe habe ich wie die anderen Ringe gemacht. Wo genau die allerdings hin müssen, ist viel ausprobieren. Das ist halt echt schwierig, weil du das Ding ja immer komplett festschrauben musst um zu sehen wie es sich dann verhält. Aber im Video habe ich auch genau meine Anordnung von den extra Ringen mit drin, musst nur genau hinschauen :)

Moin! richtig cool, wie kommst du voran? Ich habe meinen Motor mit Schneckengetriebe bei Motor-Mauer gekauft. Der Service war genial!

@@ARTVENTUREFILMS Naja nicht so wirklich weil ich nicht weiß wieviel leistung und Drehmoment ich brauche. Hast du mir bitte die Daten von deinem Motor , oder einen Link wo man den kaufen kann. Du würdest mir sehr helfen. Danke

@@patrickweber1168 Die genauen Werte kann ich dir auch nicht sagen. Das kommt darauf an wie groß deine Maschine werden soll, wie viel Kraft sie haben soll nd was du ausgeben willst. Auf der Precious Plastic Seite wird zum Schredder eine richtlinie an Newton gesagt, welche man erreichen sollte. Je mehr, desto besser. Aber ich kann dir natürlich genau das Modell und Getriebe sagen, welches ich gekauft habe. Am besten schicke ich dir nen Screenshot von meiner Rechnung. schreib mir am besten ne mail an reimer (at) rejell.com.

thanks müll 😃😃

sure, what's the issue with your machine?

There is failure in Coupling can you tell me the particular type of Coupling you used

@@spidy480 yeah for sure! I bought an elastic coupling by the company maedler. The item is called: elastic couplings RNT for taper-clamping bushes. I got size number 48 with two different sized taper bushes one 35mm of the the gearbox and the other one 20mm for the shredder. Hope that helps 🙂

Thanks man your information is precious for me 😊

@@spidy480 no worries man :)

Thanks a lot Henrik! Didn't think about selling it so far but I could definitely build another one. Where do you live though? 3 grand and it's yours 😉

@@ARTVENTUREFILMS Hey, I live in Stockholm Sweden, what about you?

@@henrikjohansson2279 Hamburg Germany. Stockholm sounds nice !

U

🙏

search for precious plastic bazar.

That's a great idea! Would love to see a video of how it works, do you have any?

@@ARTVENTUREFILMS nah there is a couple on here though you have to send it through twice but I think you can obtain one for fairly cheap

@@phuckyoutube5927 alright, thanks for the tip

@@ARTVENTUREFILMS your welcome anytime
