Iron ore pelletizing - Metso Outotec

Both straight grates and grate kilns dry the pellets out in a drying section, then bring the pellets up to a temperature of about 800-900 °C in a preheat zone, then finish the induration process at roughly 1200-1350 °C.

The process starts with up- draught drying (UDD), followed by down- draught drying (DDD), a preheating zone, a burn zone and a cooling zone. The zone for burning is called firing on traveling grates and in great kiln for kiln.

Introduction to Iron ore Pellets and Pelletizing

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

Iron Ore Pellet - an overview ScienceDirect Topics

Raw material for pellets is produced by crushing and grinding low-grade iron ores—typically of the taconite class and finer than 325 mesh (0.044 mm)—and magnetically separating the iron oxide (magnetite, Fe 3 O 4) from the siliceous gangue.

Iron Ore Pelletizing Process: An Overview

2018-7-17  Pellets are obtained byadding an appropriate amount of water to the iron ore concentrate; this is a fundamental factor in the formation and growth of pellets, which creates a surface tension that holds the mineral grains cohesive, thus allowing their handling [6, 8].

PROCESS OF PRODUCING SPONGE IRON PELLETS ...

The oxidic iron ore pellets which have been fired are usually charged to the rotary kiln together with carbonaceous admixtures and are reduced to sponge iron at temperatures below the softening temperature (Printed German Application No. 1,199,296). Numerous efforts have been made to simplify and improve this mode of processing iron ore pellets.
