DEFINITION

Classification: 75/479

Any part of the charge is consolidated by agglomerating, compacting, indurating, or sintering (e.g., pelletized ore, flux, or reductant, etc.):

(under subclass 477) Process wherein any or all components of the material charged into the rotary kiln are consolidated by agglomerating, compacting, indurating, or sintering.

(1) Note. The components such as ore, flux, or reductant may be separately consolidated or several ingredients may be combined and consolidated together (e.g., pellets of combined ore and coke, etc.).
