Mathematical model for a straight grate iron ore pellet

01/12/2008 Two types of systems are usually used for induration of the iron-ore pellets: (a) straight-grate and (b) grate-kiln process. A hearth layer of fired pellets is used in the former to protect grate bars from excessive heating. Fresh pellets are charged onto a hearth layer of the fired ones. Hot gas is blown through the layer to dry-out and fire the pellets at about 1300 °C. In the grate-kiln

LKAB’s Straight Grate Process Examining new CORE

Mining and processing iron ore are energy intensive processes with considerable energy related emissions. The final heat treatment of the iron ore pellets, done in a straight-grate or grate-kiln furnace, is the most energy intensive part of the process. A collaboration between LKAB and the Division of Energy Technology at Chalmers aims to improve the energy efficiency of the heat treatment in

Introduction to Iron ore Pellets and Pelletizing processes

Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
