The copper and aluminum chopping lines work basically
the same. The material is loaded into a MTB pre-processor and chopped into
smaller pieces to be moved to the first step of the granulator. The
smaller pieces are then checked for foreign material by hand before it goes into
the chopping phase. The material is then moved through a series of steps,
using air, magnets, gravity and movement to separate out insulation and other
small foreign material. During the complete process, each customers
material is kept separate in order to verify accurate recovery percentages.
Here are a few photos of the process and the final
material.
