rotary kiln improve ore processing

Rotary Kilns — Reaction Engineering International

Reacting two-phase flow within the firing zone of a rotary kiln used to process raw ore was simulated in order to predict and improve kiln performance. The REI combustion simulation tool GLACIER was used to model the combustion at the burner end of the kiln and to predict the heat flux to the ore bed.

Rotary kilns - Metso Outotec

The rotary kiln provides constant mixing of the pellets, bringing all the pellets to the same temperature. In a straight grate, the pellets at the top of the bed are “over cooked” and those at the bottom are “under cooked”. Higher quality means fewer fines, better reducibility and less variation in compression strength.
