agglomeration technique is pelletizing by which a mixture of iron ore, water, and binder is rolled up in a mechanical disc or drum to produce agglomerates (green or wet pellets) (Sivrikaya and Arol, 2010). A narrow size distribution in green pellets is an important criterion for the pellet
The balling section of the pelletizing plant at Hoogovens Ijmuiden consists of 7 balling drums. Each with an average capacity of 100 tons of green pellets per hour. In view of these results it was decided to equip one drum at the Hoogovens'' plant with a rubberlining although of a slightly different construction.
Jan 01, 2012· Green pellets are made by combining moist ore with a binder and rolling it into balls using either a pelletizing disk or a pelletizing drum. The green pellets are then dried, preheated, and finally heated to a temperature below the melting point of iron .
Mar 21, 2015· Understanding Pellets and Pellet Plant Operations. Pelletizing is an agglomeration process which converts very fine grained iron ore into balls of a certain diameter range (normally 8mm to 20 mm, also known as pellets. These pellets are suitable for .
agglomeration of iron ore Review of Organic Binders for Iron Ore Agglomeration. Iron ore agglomeration is a wet agglomeration process, and moist "greenballs" are subsequently dried and heat hardened at high temperatures to make pellets; the presence of binders affects the entire process from greenball formation to pellet hardening.
Jan 01, 2012· Green Pellets. The ore is crushed, ground, and concentrated in several steps to very small grain size—, over 75% less than 45 μm. Binder (bentonite or organic) and possible additives are fed in the slurry and mixed before filtering. The filter cake is transported to large balling drums or balling discs to be rolled to green ...
The formation of raw iron ore pellets, also known as pelletizing, has the objective of producing pellets in an appropriate band of sizes and with mechanical properties high usefulness during the stresses of transference, transport, and use. Both mechanical force and thermal processes are used to produce the correct pellet properties.
internally heating the ball [7]. 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].
Green ball preparation Dewatered or rewetted pellet feed is mixed with additives and then processed in the (green) ball preparation plant. This is typically equipped with 4 to 6 balling circuits consisting of a feed bin, balling drum, roller screens and conveyors for circulating the materials. The balling drum is inclined 6 to 8° to the
iron ore pellet plant wet grinding process. pellet plant wet grinding Process flow sheet for Pelletization using wet grinding process. A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in almost the same manner that one rolls a snowball,...
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; Balling process: the green pellet is the rolled pellet without any thermal process.
Iron ore agglomeration is a wet agglomeration process, and moist "greenballs" are subsequently dried and heat hardened at high temperatures to make pellets; the presence of binders affects the entire process from greenball formation to pellet hardening. In greenballs, binders interact with
If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help fire the pellets. This mixture is blended together in a mixer and fed to balling discs or drums to produce green pellets of size typically about 916mm. The green pellets are then fed to .
The powdery iron ore concentrate is mixed with a small amount of bentonite clay binder and then rolled into marblesized pellets in balling drums. The image below shows the inside of a balling drum, with thousands of round pellets within. Source: Photograph by Randy Schaetzl, Professor of Geography Michigan State University
