Sep 08, 2014· Pelletization Prosess Pelletization is the process of making spheres of high carbon contains uniform quality iron ore. Necessity of pelletization - The configuration of iron ore powder in the blast furnace is more tightly packed and restricts the air flow .For free air flow the powder of iron ore should be in spheres. The majority of iron ores must be ground to a fine particle size to allow the iron oxides they contain to be concentrated, and the concentrate must then be agglomerated back into large enough particles that they can be processed in blast furnaces. The most common agglomeration technique is pelletization, which requires the use of binders to hold the iron oxide grains together so that the ...

Peridur CMC Cellulose ethers – Nouryon

Peridur is a long chain polyelectrolyte based on cellulose and is non-contaminating to iron ore pellets. Substituted on the cellulose molecule are polar avid groups capable of immobilizing large quantities of water during the pelletization process. Being organic in nature, Peridur is eliminated during the pellet induration process. In 2010, world iron ore pellet production was 388 Mt. It could be argued that the current pellet production process has been enabled by the use of binders – practical experience has shown that it would be nearly impossible to agglomerate iron ore using rotary drums and discs without using a binder.

Pelletization -

Pelletization is the process of transforming iron ore fines into spherical pellets through agglomeration and induration. These pellets are then used as feed to a blast furnace or direct reduction systems to produce iron. Waste Management By Pelletization Of Iron Ores Fines In Indian Context 122 prior to induration with the help of an electronic mass balance (for accurate reading). Once weighed, the pellets were indurated in a pre-heated muffle furnace at varying temperatures, each for duration of 45 minutes.

Effect of Bentonite on the Pelleting Properties of Iron ...

The pelletizing process consists of three stages: (1) mixing of the raw material to produce the raw pellet, (2) pellet enlargement, and (3) pellet hardening. During the pelletizing, the atomized water was added in the area of disc pelletizer. The water was deionized to avoid the effects of water chemistry on pelletization performance. Iron Ore Pelletizing Aids Iron Ore pelletization is a tumble/growth agglomeration mechanism for solid particulates, which must comply with two key points. The first point is to reach, during the balling stage, the capillary state without exceeding it.
