This shredder is used to convert plastic waste into flakes that can be used in Precious Plastic projects.

We have a small selection of perforated metal plate (Lochblech) that could be adapted (cut and perhaps re-drilled) to be the "sieves" determining the particle size that comes out of the shredder.
