I had the privilege of building a shredder for our office at the Native Shoes headquarters in Vancouver. The idea was just a pipe dream months ago, but after several weeks of work, I was able to finish it off. Features and photos below:
-2hp 3-phase motor
-Variable frequency drive (forward/reverse and speed control) – 30-60 RPM
-30:1 gear reduction
-interchangeable shredder screens
-keyed power switch
-emergency stop switch
-fire extinguisher
-powder coated parts
-6″ pivoting casters
The big add on’s to add a level of safety to the project were the e-stop, the hopper lid, and a keyed power switch. This will prevent anyone from using it without the proper key.
I am a new member of this project and super impressed by the shredder you built, Bravo! Would it be possible to come by and see it working ? My hope is that we can build one in this area, North Burnaby and learn more about this while providing an answer to the incredible amount of plastic, eventually taking this concept to Mexico. Hope to hear back from you
Hi @nic0, the screen I built has holes that are about 1/2 and inch in diameter. However, with the material we are using (EVA), it was jamming up, and we’ve actually switched to using no screen at all.
Thank you all! I felt like the safety features were a must have for such an aggressive machine (massive blades). Perhaps @davehakkens can work some of these into the 3.0 plans!
