Consider a shredder as a kind of recycling machine that allows you to dispose of material, paper, wood, plastic, etc., without great effort.
This works as follows: They are carrying materials across a conveyor belt in the funnel of the shredder. This cuts the materials into small pieces, which makes it easier to recycle. After the mill has been shredded, you can recycle it via further recycling plants and finally recycle the recyclable material. There are different variations of these so-called shredders. On the one hand, there are single or multi-shaft shredders equipped with sharp, robust knives. On the other hand there are models that separate and crush objects.
