13.  Recycling industry

Recyclable materials can be brittle (glass, ceramics, cast iron), ductile (metals or plastics, polymers, etc.) or elastic (plastomers). Mineral crushing and grinding equipment, working in the brittle fracture domain, is often ineffective in fragmenting recovered materials, for which shear and attrition forces must be brought into play. It is therefore necessary to use cutting equipment .

The materials to be fragmented are characterized by an extreme variety, resulting from their heterogeneous constitution, their mixture, their inconstancy of supply resulting from their diverse origins. Scrap...
