  • Introduction to Iron ore Pellets and Pelletizing processes

    There are several iron ore pelletizing processes/technologies which are available for the production of the pellets. Some of these are (i) shaft furnace process, (ii) straight travelling grate process, (iii) grate kiln process, (iv) cement bonded processes (Grangcold process, MIS Grangcold Process, and char process etc.), and (v) hydro-thermal

  • Iron ore pellets and Pelletizing processes Vale

    Iron ore pellets and Pelletizing processes. Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel. It is the process of converting iron ore fines into “Uniformed Sized Iron Ore

  • Iron Ore Pelletizing Process: An Overview IntechOpen

    10.07.2017· The iron ore pelletizing process consists of three main steps: Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives—anthracite, dolomite—and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process;

  • Iron Ore Pelletizing Process: An Overview

    50 Iron Ores and Iron Oxide Materials Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s. Bentonite promotes the forma- tion of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing.

  • Beneficiation Plants and Pelletizing Plants for Utilizing

    Among iron ore products, fines and pellet feed are so fine that they cannot be charged as-is into a blast furnace or into a direct reduction furnace. The processes for agglomerating them into chargeable material are sintering and pelletizing; the main raw material for the former is fines and for the latter, pellet feed.

  • 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. The fine particles are reconstituted into moist pellets about 1 cm in diameter, and then indurated by heating to temperatures approaching 1300 °C. This is

    The process comprises four steps: Raw material preparation and mixing ; Green pelletizing ; Pellet hardening (indurating) Hearth layer and product screening ; In order to adjust the moisture content, water is added in the mixing step. The ore is then mixed with small amounts of binding agents. Fluxes such as limestone, olivine, and dolomite give the pellets the necessary physical and metallurgical properties
