The shredder build .
Some things to consider before building the shredder.
1 what power do you have, eg single phase or 3 phase
2 will u use a reversing switch. if so you will have to have a 3 phase motor.
3 the speed or the shredder , using belts and pulleys or reduction gear box.
4 what will you use to melt your plastic , Gas or electric heating.
these are some of the challenges i had to deal with to get my unit up and running and reliable.
also i fitted a fly wheel on my shredder to give it good momentum
I welcome any questions re the building and running the shredder.
do you have any pictures???
im verry intrested
Single phase is enough, I think 750w it’s enough but there are 1100w and 1500 too and is possible to reverse without problems.
Gearbox is safer than pulley but more expensive, the flywheel must be put on the motor shaft because is faster, putting it in the shredder shaft has no sense.
thanks, no, Fly wheel has to be on the shredder end not motor side . It is the momentum of the flywheel that takes some of the load off the motor.
A single Phase motor will fail with a reverse switch . What wiring diagram did u would u have used.
Yes, flywheel needs to be on the motor-side, but 750W is definitely not enough. I would go at least for 2,2kw motor. And pulley and belt is maybe a less good idea than a chain (motorcycle…).
Yes, you can change direction with a single phase motor, but if you have three_phase-current available i would take a three-phase-motor.
Thanks for your valued inputs..
