cars from high temperatures. Green pellets are loaded onto the hearth layer to form a packed bed of pellets. Straight grate induration machines are typically designed such that pellets pass through updraft-drying (UDD), downdraft-drying (DDD), pre-heating (PH), firing (F), after-firing (AF), and cooling (C1 & C2) zones.
