Hello guys!

I am building a shredder and now I just have to attach the motor and start shredding plastic … I hope.

I found an electric motor from a washing machine and I want to make sure that it will work.

So, can anybody help me with some questions?

What’s the minimum torque? I will recycle mostly ABS but is preferable to be able to shred other plastics. I am using the same blade configuration as Dave.

Is there any recommended maximum speed? Dave used 70 rpm but I have seen some projects using 200 rpm.

I will study the influence of the flakes dimension on the mechanical properties of the material. Do you have any suggestion of 5 different maximum dimensions to study?

Thank you so much for everything! I have made some change in the shredding chamber and I will share it when finished. Hope that it can help someone.

Hugs!
