These systems include:

  • All storage silos fitted with screening, feeding and extraction systems

  • Anode covers material distribution to potroom

Pots and GTC interfaces integration

For customers, the integration of the whole network between GTCs and pots in a global offer reduces the number of interfaces and provides a global guarantee.
