My Shredder

27/02/2017 at 01:18

It’s been a while since I started my Shredder project but didn’t have the time to actually finish it, but I can now say that my shredder is 99% complete (I say 99% because I have not attached the power cable yet, but I already have it)

Here are a few tips:

*Don’t use a motor that is less than 2hp. I purchased a 1/2HP motor and it does shred plastic, but the threaded part of the bottles makes the motor halt. A 2HP or more motor should not have this problem, and if possible, get a triphase one.
*I did not want to buy a perforated sheet of metal because I only needed a small square piece and the hardware store would not sell the amount I needed, so I grabbed a perforated metal sheet I found in an old speaker and it worked just fine (see pictures below)
*On my Shredder’s frame I soldered 4 small pieces of square tube that I can use to put a piece of wood, that will serve as a base for a trash can that will collect all the shredder plastic
*Get a DPDT rocker switch, that will allow you to reverse your shredder motor if the shredder gets jammed

Hi Guys, I have a burning question in mind.

What if I add extra blades and make the shredder longer, will it give higher capacity/output of the plastic that will get shredded?
and want about the engine? can the same capacity work well if we add more blades?

Does anyone have ever try it before?

I would really appreciate it if someone can reply to me about it.
thank you very much in advance.

Cheers, Nila from Nijmegen.

@nonanoplastic With more blades and more plastic, you will need alot of power from your Motor. If you have that, then go for it, but as you see on the video that @xxxolivierxxx shared, then it has a hard time just shredding one bottle-button. I would advise to just go for the set 14 blades, and make it work with a motor that fits.
That would be most efficent and low cost, as i see it 🙂

@vk7dy yes but it might be too complex for humanity to understand 🙂
My motor had 6 wires and 2 of these wires are connected directly to the starter coil/capacitor (Wires 5 and 6 on my drawing). I used a simple DPDT switch, when the switch is in the middle position, the starter coil is powered but the motor does not spin.
This is not the most efficient/elegant solution, but it works just fine and it’s extremely cheap

Hello @xxxoliverxxx,

I have a motor with similar specifications to the one you used in your build however on the gear reducer tag it says max output hp is .75 and the torque is around 560 lbs/in with an rpm of 68. I am curious if this sets my motor apart from yours? Unfortunately I have already purchased it and am hoping I didn’t waste money on something that won’t work. Any input you can offer is appreciated!

Thanks
