The green pellets produced in a pelletizer are too weak to withstand any type of severe handling; further processing at elevated temperatures is required to strengthen them before the pellets are shipped to a customer. The high-temperature processing protocol depends on the type of pellet. For RHF-based operations (self-reducing iron oxide/carbon composite pellets), the pellets are dried in ...
