Have you ever seen Breaking Bad? The AMC tv series? It’s the same idea, obviously different products/machines.
OnTopic: It’s a very good idea, I think it could be feasible.
Flo, what a great answer. May I ask if there’s a mid-situation? I mean not ‘home based method’ but not this one of 100k volts.
I’ve heard something related to their floating properties, can anyone please confirm this?
@javierrivera, I’ve a question! I’ve understood -almost- all you’ve mentioned; if you have a nozzle of 50mm diameter it would be -mathematically- enough to fulfill the area he needs to have because of the final size of the ‘product’, but: Is there a possibility to vary the speed and, because of that, get the some output but with a smaller nozzle? Please let me show to you my idea with an example:
– Speed: 1
– Nozzle: 50mm diameter
– Output: perfectly covering the area needed (output of 1960 mm^2, needed: 1660 mm^2)
– Speed: 0.5
– Nozzle: 25mm diameter
– Output: the same as above
Sorry for my english, I hope you can undestand which is my question: Is it possible to ‘play’ with the speed in order to have the same result?
Very good job, but as mentioned, I would make some little changes:
– The gearing in the other way round (the bigger one in the shredder, the smaller one near your feet.
– The bigger one has to be even more big. You need a 1:5 ratio (at least)
– You could add a Flywheel in order to create a ‘momentum’ during the shred; if you don’t, the shredder could jam frequently.
Not a change, but a question for everyone that can help. Is that chain tight enough? I am not sure, but it seems to me that it is loose.
Hello, very impressive work and also thank you for sharing every step of the process until you’ve reached the ‘final method’.
I have 2 questions:
-1- How do you get that uniform colour? Do you have to sellect the bags one by one and only use the ones that have the very exact colour?
-2- Can we get this result (fabric/textile) with other plastics? For example melting plastic bottles and then while using a rolling pin create a thin uniform piece of plastic sheet.
Thank you, and sorry for my english!
In addition to olivier’s post, there are some plastics such as PVC that in any chemical process (melt at correct Cº and also when burned) releases toxic fumes. Others, such as the ones you’ve mentioned, only release toxic fumes WHEN BURNED. If you are working at correct melting degrees, you will have no problem.
In all the cases is highly recommended to work in a ventilated area.
Truly happy for the news, as I said, I always thought that it would be much more difficult. Thank you very much sonik.
Really interested in this. Also it’s kind related to the real mission, going greener, so in the long term it will always be more positive.
If it’s helpful, a 3HP electric engine (for the shredder) consumes approximately 2,1 Kw per hour, so here’s my question. Do you have information about the size of the solar panel in order to obtain, at least, 2,1Kw?
Wow, I did not think of that, in fact I thought for sure It was something we needed. Alright, bare ambient temperature water then? Or hot water would be helpful?
Thank you sonik,
P.S: Then, only by staying in the water for some hours and a little bit of movement (like the picture of the ancient method posted above) its fine?
Very good video, already liked in YouTube. Also, very good project, please keep us updated.
At the end of the term, what results are you expecting? It’s only a one-year project, or are you planning to continue it?
Once again, really good project.
Awesome idea man, it’s a big improve in the power. Question: What about the consumption in general? I mean, the idea is to know which is cheaper in an industrial application, gas or electricity.
Keep us updated,
sonik, I am a newbie, but I think if there are lots of sources where the plastic can come from, It’s a waste of time and money to select the ‘type of dirt’ and where to clean. Not only water, but also soap/detergent is needed in every process of cleaning.
But I am still with my previous question: What comes first, the cleaning or the shredding? (It’s like the chicken or the egg).
Thank you All,
Great news hugonator, always going forward. Yes please, I’ll come by soon to see if there are more news. Good luck!
rafa, what a great way to help, honestly. Question: Have you considered (or maybe you’ve already done it) donating to Dave? I mean, to the original Precious Plastic proyect.
Why? Maybe he will be able to do greater things, and then we will all be able to get benefits from that donation. (p.e. a more efficient or quick V4 of Precious Plastic).
Once again, what a worthy way to help. Keep it Up.
This is the most important part of the question (for me): Wash before or after shredding?
Before: You can wash and then select the type of plastic in order to store. Some parts may NOT wash propertly (p.e. a closed bottle, or a tiny piece). It’s more difficult to fully dry.
After: You will wash it propertly, but it is complex as you have to wash them in groups (by color, by type of plastic, etc).
So, my question: Before or after Shredding? In industrial size, in order to wash I would have a big recipient full of water + chemical [detergent] and a slow but continuous movement (with a rotating propeller/helix).
After X time (to determine according the detergent used, the movement and the source of the plastic) I would take the plastic to another container where I would apply centrifugal force.
It’s done, plastic clean and dry.
(Sorry for my english)
@davehakkens, related to previous comments, I have my own:
– I don’t think its a mistake to have .nl/community/forums/forum/precious-plastic (its a bit redundant, but its OK).
– I DON’T think you should create a new forum (like preciousplastic.com/forum or similar) because many people won’t understand what it’s happening and maybe won’t re-register. Its no good to lose some friends, is it?
– It is a good idea to enhance the ‘search button’ in order to avoid lots of posts of the same topic.
– I DO recommend to add a litter green button (or an envelope) in the general area of <u>topics that we have already posted</u>. Why? I have already commented in 4 or 5 topics and I don’t remember on which of them. Related to the next bullet, I can’t see (and can’t check them all every hour) If there’s a new response or not.
– I DO recommend to create a ‘recently updated posts’ widget (or similar) in the TOP of the forum (.nl/community/forums). It has to be similar to ‘Activity’ but only with new messages (including new topics, of course). That will significatively increase user engagement and you know, more activity = more precious plastic.
– I DO recommend to add a ‘Report’ button. Why? Not trying to be mean or aiming to issue sanctions, but there are posts that need to be replaced (for example they are about ‘how to build a shredder’ and are posted in ‘General ideas and suggestions’ and not in ‘Machine development’.
P.S: I’m a webmaster, so let me know if I can be of any help.
I have a question about moulding plastic with compression and its temperature. If you apply pressure into a piece of plastic at its 80% of molding temperature, does it efectively mold?
I am interested on this in order to know if it can be used in industrial production; if you always work at 80 or 90% of the moulding temperature (but apllying pressure), it will be much more complicated to get a piece burned.
@jegor-m This is a really great story, full of details. I have a question, for big pieces of plastic recicled by extrusion (bigger than the aluminium can) you mentioned that it has to cool down slowly (p.e. in the oven), right? If we apply some pressure and always with a controlled temperature (I mean avoiding overheating), do we still need to cool it down slowly?
