  • Introduction to Iron ore Pellets and Pelletizing processes

    Raw material preparation During the process for pelletization iron ore concentrate from iron ore beneficiation plant is dried and heated to around 120 deg C. The dried material is fed to the ball mill for grinding. Concentrate/ground iron ore of typical size 80 % less than 45 microns (0.045 mm) with a moisture content of around 9 % is required for the pellet

    21/3/2015· The process of enriching taconite ore involved grinding the ore to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high grade ore is in the form of fine particles, as small as 0.1 mm or less, which are not suitable for sintering. This issue led to the development of the pelletizing process.

    10/7/2017· 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 formation of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing. Despite its low cost, the inorganic compounds from bentonite are contaminants increasing the amount

    The preparation of iron ore pellets begins with the crushing and grinding of iron ore into a fine powder, and adding reducing additive coke (C) and binding agents and mixing. The mixture is added to a pelletizing machine or ball mill along with a pre determined amount of moisture to form green pellets. These green pellets are air dried and subsequently oven dried to harden the pellets. Green pellets are

    The plant has enrichment facilities that enable the silica in the concentrate to be reduced if necessary, according to customer requirements for higher quality pellets. After this optional stage, the concentrate is taken to one of the six grinding balls with water and additives. As they knock together inside the grinders, the balls made of a very hard alloy reduce the particles of concentrate to the size of a grain of dust.

Examination of the many load-deformation curves recorded during the constant loading rate tests on dry pellets showed a linear relationship between the force applied to the pellet and its resulting deformation. It was not surprising, then, to observe a similar result for tests on dry pellets performed at a constant rate of deformation: if the pellet is deformed at a constant rate, the force with which the pellet
