shredder is done in junkyard style. it’s nice to have structure to hold it. is working fine, can maybe grind ~10kg of PET bottles / hour. 5 mm mesh is not s ideal as it could get jammed at the bottom and blades get hot real quick. got good result without using mesh, just straight thru the box twice. 10 mm and removable mesh seems like a good idea for now.
on the motor:
In precious plastics the rpm is much slower and seems to work just fine.adjustable motor could be nice? lets say a 3 kw servo motor with gear. for example we might want something faster when grinding something softer like styrofoam or we want something slow when grinding harder stuff.
injection machine is a bit messy, the tubes get rusty and the tip doesn’t get heated nicely. also some ideas for molding.
thanks for the info, do you think it’s a good idea to shred PET bottle without taking the caps off ? and separate them after during washing?
that machine looks very powerful in the video. how did you wire your motor? im connecting power directly to a 220v 1.9 kw motor. seems like a wrong way to do so . would be nice to get some tip from you .
